TBD-08-006 Page 7 of 56, Rev. 0 1.0 Executive Summary The Plum Brook originates in th e southwest corner of the 6400 acre NASA Plum Brook facility in Erie County, Ohio. It terminates in Sandusky Bay on the shore of Lake Erie northeast of the city of Sandusky. Cesium-137, Co-60, and possibly other radionuclides, entered the Plum Brook as a result of Plum Brook Reactor Facility (PBRF) operations from 1963 to 1973. The radionuclides were released in liquid effluents through a monitoring station into a man-made ditch that emptied into the Plum Brook near th e northeastern boundary of the PBRF. As part of the PBRF decommissioning, an investigati on was conducted of residual radioactive contamination in soil and sediment on the facility and in the Plum Brook. This included measurements of sediment samples collected from the Plum Brook north of the facility in the summer of 2005. From these initial measurements, it was determined that Cs-137 and smaller concentrations of Co-60 were present in the Plum Brook in areas accessible by the public.

An extensive campaign was conducted by NASA from 2005 through 2007 to determine the levels and extent of radioactive contaminants in the Plum Brook and environs. Samples of soil and sediments were collected from 900 locations along the four mile stream course from the PBRF to Sandusky Bay. The samples were analyzed by gamma spectroscopy for Cs-137 and other gamma emitting radionuclides. It was found that Cs-137 is the predominant man-made radionuclide in the Plum Brook with detectable concentrations measured along the stream course from the PBRF and into Sandusky Bay. Cobalt-60 was detected in less than 10 % of the samples and at average concentration of less than 1 pCi/g. Most of the Co-60 was measured in sediment samples collected from the Plum Brook near the PBRF. Detectable conc entrations of Cs-137 were measured in sediments deposited in the stream bottom, along the stream banks and in delta deposits in the stream mouth and surrounding we tlands. Detectable concentrations of PBRF radionuclides were not found in Plum Brook water.

The NASA, PBRF Decommissioning Program Manager directed that a study be performed to estimate radiation doses that could be received by members of the public from contaminated Plum Brook sediments and to obt ain derived concentration guid eline levels (DCGLs) for the sediments. Accordingly, the RESRAD © computer code developed by Argonne National Laboratory and approved by the NRC was used to perform an initial dose assessment. Exposure scenarios developed by the NRC for assessment of radiation doses to future occupants of decommissioned nuclear facility sites were used as the starting point. They were modified to describe exposure conditions for members of the public that could come in contact with contaminated Plum Brook sediments [NASA 2008].

Doses to members of the public were calculated for four exposure scenarios. The scenarios are based on potential exposure conditions representative of the major stream hydrologic regimes. Two residential scenarios were placed in the stream meander sections. Most of the near-stream residences are located in these sections. These include the stream and stream banks that run from the Northern PBRF boundary to the Plum Brook Country Club. These exposure scenarios are

the: TBD-08-006 Page 8 of 56, Rev. 0 Suburban Gardner. This scenario assumes that a resident grows vegetables in a garden on soil that is supplemented with (mixed with) contaminated sediments excavated from the

nearby stream bank. Radiation exposure is received primarily from direct exposure while working in the garden about 120 hours a year and from consumption of vegetables grown in the garden. Brook-side Resident. A residence is assumed to be constructed on land contaminated with sediments deposited in the vicinity of the stream during a large flood event prior to construction of the home. Exposure to the re sident is received primarily from direct exposure while inside the hous e (1096 hours per year) and while occupying contaminated outdoor areas while doing yard work (80 hours per year).

Two scenarios are set in the flood plain and estuary. Here, the principal means of public access to the stream are through the Plum Brook Country club golf course and the Putnam Nature Preserve. The scenarios are the:

Country Club Worker. The dose receptor for th is scenario is a worker at the Plum Brook Country Club, located on the Plum Brook about 2 1/2 miles downstream (north) of the PBRF. The worker is assumed to spend about 15 hours a week traveling on and maintaining landscaping adjacent to a cart path constructed on contaminated sediment

used as fill. Recreationist. It is assumed that the most likely means for public exposure in the estuary is through recreational use. The dose receptor is a fisherman who occupies the stream and stream bank while fishing in the stream m outh-estuary located between Us Rt. 6 and Sandusky Bay. The fisherman spends about 10 h ours a week for 10 weeks a year at the stream and consumes game fish caught there.

The initial dose assessment was performed under the assumption that a final status survey would subsequently be required to ensure that members of the public would receive less than 25 mrem/y. The dose assessment focused on the exposure from Cs-137. It also used a simplified source term description consisting of a single-layer source volume for each scenario and assumed an average Cs-137 concentration of 1 pCi/g throughout the Plum Brook. The highest dose from exposure to Cs-137 was obtained for the Brook-side Resident, 0.17 +/- 0.17 mrem/y per pCi/g (average dose +/- one standard deviation). This result was used to calculate DCGLs corresponding to a range of dose criteria that could provide an acceptable basis for evaluating potential corrective actions. It was determined that the DCGL for Cs-137 could be as high as be 144 pCi/g average concentration without exceeding the 25 mrem/y dose criterion [NASA 2008]. These results were presented to the NRC and the Ohio EPA in a public meeting in September 2008 [USNRC 2008]. Alternative approaches were discussed for demo nstrating that areas of the Plum Brook accessible to the public that were impacted by contaminated sediments satisfy the 25 mrem/yr dose criterion. The alternative approaches are:

Establish DCGLs and perform final st atus survey using MARSSIM guidance Characterize and perform a dose assessment.

TBD-08-006 Page 9 of 56, Rev. 0 It was agreed that the latter approach was the most practical and was acce ptable to all parties. The NRC identified requirements for an acceptable dose assessment [USNRC 2008]. Subsequently NASA determined that additional information and evaluation were required. Two tasks were identified. A detailed description of the distribution of radionuclides of PBRF origin in the Plum Brook and environs was to be developed followed by a revised dose assessment. The results of the present dose assessment are summarized:

The dose to members of the public from Plum Brook sediments contaminated with Cs-137 and Co-60 was calculated for four exposure scenarios. The scenarios represent a range of possible conditions whereby member s of the public could receive radiation doses from contaminated sediments. The cal culated dose to indivi duals exposed in the four scenarios range from 0.65 to 1.17 mrem/

y. The average of the doses to the four scenario receptors is 0.88 +/- 0.22 mrem/y.

This result shows that the dose to an individual is well below the 25 mrem/y dose agreed by the principal stakeholders as being acceptable for the Plum Brook areas impacted by contaminated sediments. This conclusion is further supported by direct measurements of radiation doses and dose rates at locations on the Plum Brook selected to represent settings similar to those of the exposure scenarios. The measured doses are less than the calculated doses at three of the four locations and in close agreement with the calculated doses at the fourth location.

Additional perspective is provided by comparison with the dose to the public from the Cs-137 fallout from atmospheric weapons testing that remains in the environment. The annual average dose to individuals in the northern hemisphere from fallout Cs-137 is reported to be about 0.5 mrem/y (with an estimated uncertainty of +/- 100 %.). Thus, the calculated doses from exposure to Plum Brook sediments are indistinguishable from the "background" dose received from the fallout Cs-137 burden in the Plum Brook watershed.

TBD-08-006 Page 10 of 56, Rev. 0 2.0 Introduction

The Plum Brook is one of several surface streams that drain the 6400 acre NASA Plum Brook facility in Erie County, Ohio. It originates in farmland south of the facility and terminates in Sandusky Bay on the shore of Lake Erie northeast of the city of Sandusky. Cesium-137, Co-60, and possibly other radionuclides, entered the Plum Brook as a result of Plum Brook Reactor Facility (PBRF) operations from 1963 to 1973. The radionuclides were released in liquid effluents through a monitoring station into a man-made ditch that emptied into the Plum Brook

near the northeastern boundary of the PBRF. As part of the PBRF decommissioning, an investigation was conducted of residual radioactive contamination in soil and sediment on the facility and in the Plum Brook. This included measurements of sediment samples collected from the Plum Brook north of the facility in the summer of 2005. From these initial measurements, it was determined that Cs-137 and Co-60 were present in the Plum Brook in areas accessible by the public.

This report presents an assessment of radiation doses to members of the public that could come in contact with sediments contaminated with ra dionuclides of PBRF origin. The objective is to demonstrate that the doses are less than the NRC 25 mrem/yr dose criterion. The present report is a revision of an initial dose assessment performed in 2008 [NASA 2008]. It is based on a recent and more complete description of sediment characterization [NASA 2009].

3.0 Background

An extensive campaign was conducted by NASA from 2005 through 2007 to determine the levels and extent of radioactive contaminants in the Plum Brook and environs. Samples of soil and sediments were collected from 900 locations along the four mile stream course from the PBRF to Sandusky Bay. The samples were analyzed by gamma spectroscopy for Cs-137 and other gamma emitting radionuclides. It was found that Cs-137 is the predominant man-made radionuclide in the Plum Brook with detectable concentrations measured along the stream course from the PBRF and into Sandusky Bay. Cobalt-60 was detected in less than 10 % of the samples and at an average concentration less than 0.5 pCi/g. Most of the Co-60 was measured in sediment samples collected from the Plum Brook near the PBRF. Detectable conc entrations of Cs-137 were measured in sediments deposited in the stream bottom, along the stream banks and in delta deposits in the stream mouth and surrounding wetlands. Detectable concentrations of radionuclides of PBRF origin were not found in Plum Brook water.

An initial dose assessment was performed in 2008 to determine derived concentration guidelines (DCGLs) for the sediments. It was performed under the assumption that a final status survey

would subsequently be required to ensure that members of the public would receive less than 25 mrem/y. It used a simplified source term description consisting of a single-layer source volume for each scenario. The highest single nuclide doses for unit concentration were obtained for the

TBD-08-006 Page 11 of 56, Rev. 0

Brookside Resident. They were: 1.7 +/- 01.7 E-01 and 6.79 +/- 7.08 E-01 mrem/y per pCi/g (average dose +/- one standard deviation) for Cs -137 and Co-60 respectively. These results were used to calculate DCGLs corres ponding to a range of dose crit eria that could provide an acceptable basis for evaluating potential corrective actions and a final status survey. It was determined that the DCGL for Cs-137 could be as high as be 144 pCi/g average concentration and Co-60 up to 36 pCi/g without exceeding the 25 mrem/y dose criterion [NASA 2008]. These results were presented to the NRC and the Ohio EPA in a public meeting in September 2008 [USNRC 2008]. Alternative approaches were discussed for demonstrating that areas of the Plum Brook accessible to the public impacted by contaminated sediments satisfy the 25 mrem/yr dose criterion. The alternative approaches were: Establish DCGLs and perform final st atus survey using MARSSIM guidance Characterize and perform a dose assessment. It was agreed that the latter approach was the most practical and was acce ptable to all parties. The NRC identified requirements for an acceptable dose assessment [USNRC 2008].

The doses calculated in the initial dose assessment for Plum Brook sediment DCGLs were obtained from dose modeling performed with the RESRAD computer code [NASA 2008]. 1 This was accomplished following guidance issued by the US Nuclear Regulatory Commission (NRC) for dose assessment and development of site-specific DCGLs [USNRC 2003]. The NASA PBRF Project Manager requested that similar methods be used in a revised dose assessment to demonstrate that the 25 mrem/y dose criterion is satisfied in lieu of a final status survey. 2 It would take into account a more detailed source term description for from Plum Brook sediments.

Principal steps for performing environmental dose assessments within this framework and followed in the present assessment are:

a. develop a conceptual site model

b. select appropriate exposure scenarios

c. determine values for key dose modeling parameters and

d. calculate the dose to individuals most likely to be exposed using an NRC-approved computer code such as RESRAD.

Conceptual site models are representations of the environment at a contaminated site that describe the physical, chemical and biological processes that determine the transport of contaminants from the points of release through environmental media to exposed individuals or 1 The RESRAD code was developed by Argonne National Laboratory for the US Department of Energy [ANL 2003]. The NRC has approved it for use by licensees to determine compliance with the NRC Decommissioning license termination rule [USNRC 2003]. 2 Per this request, the dose assessment utilizes the RESRAD code and has adapted exposure scenarios identified by the NRC for use at urban sites to simulate conditions at the Plum Brook. TBD-08-006 Page 12 of 56, Rev. 0 groups [ASTM 1998]. The conceptual site model provides a framework for assessing doses or risks from the contaminants released from a facility.

The exposure scenario incorporates the contaminant source characteristics 3, environmental transport pathways and human dose receptor characteristics into a dose calculation model. Exposure scenarios for environmental dose modeling describe: how the radioactive material moves from the source through the environment where and how humans are exposed to the environmental concentrations (and to direct radiation from the source) individual habits that determine exposure [USNRC 2003].

A scenario is "constructed" by identifying pathways and selecting values for parameters in the equations that describe the transport of radionuclides. The parame ters are classified as physical, metabolic (or biological) and behavioral. Physical parameters include site characteristics and the area, thickness and depth below the surface of the contaminated soil. They also include geologic, hydrologic and meteorological parameters that describe the site and the movement of radionuclides through the physical environment to intermediate (food chain) pathways and direct pathways to the receptor. Metabolic parameters describe the transport of radionuclides through food-chain pathways. Finally, behavioral parame ters describe the physi cal occupancy, dietary habits, drinking water intake a nd breathing rates of individuals exposed to direct radiation, contaminated food, water and air.

The Resident Farmer scenario was used by NASA to derive DCGLs for the principal radionuclides of concern in PBRF soil [NASA 2006]. In this scenario, a farmer moves onto a site that has been released for unrestricted use, grows and consumes food and uses water drawn from an aquifer under the site. The Resident Farmer scenario is illustrated in the schematic in Figure 1. The exposure pathways include: external exposure from contaminated soil inhalation of suspended soil ingestion of soil ingestion of drinking water consumption of plants and plant products grown in the contaminated soil and irrigated by water from the aquifer consumption of products from animals fed by plants grown in the contaminated soil and water from the aquifer consumption of fish from a pond supplied with water from the aquifer [USNRC 2003]. The Resident Farmer is a standardized generi c scenario used to obtain soil concentration guidelines (DCGLs) for release of sites for unrestric ted use. It is expected to yield conservative predicted values of dose per unit concentration of radionuclides in soil [ANL 2001]. "The 3 The terminology used by the US NRC to describe radiation source characteristics in environmental dose modeling is "source term abstraction" [USNRC 2000].

TBD-08-006 Page 13 of 56, Rev. 0 generic models and default parameters are intended to estimate the upper range of the dose that an individual could receive and are expected to overestimate th e dose at most sites" [USNRC 1998]. Dose assessments using this approach estimate prospective risks (dose) to reference individuals. Assessment of doses from contaminated sediments th at have been transported to publicly accessible areas in the vicinity of the Plum Brook requires some modifications to this approach. This suggests the use of exposure scenarios that are more re presentative of exposure conditions in the Plum Brook environs. In this li ght, other scenarios have been identified by the NRC. They include an urban or suburban residen tial scenario which is described as "a subset of the Resident Farmer scenario", for urban or suburban settings where farming is not a realistic projected use [USNRC 2003]. Other scenarios identified by the NRC fo r urban and suburban settings include:

Recreational User - at a site wher e only recreational use occurs Maintenance Worker - similar to a r ecreational user scen ario, but involves groundskeepers or building maintenance workers [USNRC 2003].

The RESRAD code can accommodate exposure scenarios such as those identified above by selecting appropriate pathways from the total set of pathways and by adjusting values of parameters in the equations that calculate th e transport of radionuclides through the pathways [ANL 2001]. This is the approach taken in the present dose assessment.

TBD-08-006 Page 19 of 56, Rev. 0 5.0 Site Description - Plum Brook Conceptual Site Model

What follows is a conceptual site model for the Plum Brook and environs. It includes a description of the geology, hydrology, and environmental characteristics that determine how Cs-137 and other radionuclides entered and were transported downstream in the Plum Brook. The model includes a description of demographics and land use to identify exposure pathways. To provide perspective on estimated doses from contaminated Plum Brook sediments, the impact of the co-existing environmental burden of Cs-137 from nuclear weapons fallout is discussed. 5.1 Overview

Plum Brook is one of several streams that drains the NASA Plum Brook Facility It originates in farmland south of the facility and empties into Sandusky Bay, a total stream course distance of about 6.5 miles. The portion of interest is the stream and its nearby environs that contains or is impacted by sediments contai ning Cs-137, Co-60 and possibly other radionuclides released from the PBRF. This portion of the stream course comprises the Plum Brook watershed that lies be tween the juncture of Pentolite Ditch and Sandusky Bay, a stream-course distance of about 4 miles. In its course from PBRF to the Bay, the stream passes through farmland, residential areas, commercial areas, municipal land, a country club and a protec ted conservation area (a wetl and). The entire drainage area (or watershed area) associated with the Plum Brook and its tributaries, comprises an area of about six square miles. Only a portion of the watershed, an area of 1.6 square miles comprises the area potentially impacted by the contaminated sediments. This is the area drained directly by the Plum Brook that lies between the northern PBRF boundary and Sandusky Bay. The watershed includes porti ons of Perkins and Huron Townships on the outskirts of the city of Sandusky.

5.2 Geology of the Plum Brook Drainage Area

The Plum Brook watershed terrain is nearly flat with a gentle slope that trends from south to north dropping in elevation from 620 feet above sea level at Pentolite Ditch to 570 feet at Sandusky Bay. The Plum Brook drainage area consists of surface glacial till underlain by shale, mudstone and limestone formations [Hatfield 1988]. The glacial till comprises dense clay and unconsolidated sand, silt and gravels. The glacial till typically ranges from 10 to 20 feet thick and lies above fractured-weathered shale and limestone beds. The stream ravine is largely confined to surface deposits. It occasionally contacts thin beds of shale and limestone above the underlying water-bearing formation, the Delaware Limestone. Figure 2 shows a cross section view of the geology in the Plum Brook watershed. Note that the vertical scale is exaggerated.

The Delaware Limestone is a bedded, fractured water-bearing limestone formation ranging from 15 to 20 meters thick in the vi cinity of Sandusky. It is underlain by older

TBD-08-006 Page 20 of 56, Rev. 0 limestone formations up to several hundred feet thick. The water table, or potentiometric surface, 4 in the vicinity of the PBRF is encount ered at two levels. A shallow, unconfined water table is observed in permeable surface deposits, at typical depths of 10 feet below land surface (BLS). An artesian or confined potentiometric surface in the Delaware Limestone is encountered at a typical depth of 20 feet BLS near the PBRF. The top of the regional aquifer (a confined water-bearing zone) associated with this potentiometric surface is observed at about 50 feet BLS in the vicinity of the PBRF [Haag 2008d].

5.3 Stream Hydrology and Surface features

The Plum Brook watershed is divided into drainage areas for purposes of flow estimation as shown in Figure 2 [Haag 2007b]. For the simplified conceptual model, three major surface drainage regimes are described - each has been modified to varying degrees by human activities. Modifications include culverts, highway overpasses, storm drain outfalls and dredging. From its origin at th e southwest corner of the NASA Plum Brook Reservation to the juncture with Pentolite Ditch near th e northern PBRF site boundary, the stream comprises a series of channels and ditches, some of which have been modified and straightened. From the PBRF northern boundary to the interior of the Plum Brook Country Club (PBCC), the Plum Brook is characterized as a narrow meandering stream and from the PBCC north to Sandusky Bay, the stream widens into a floodplain-wetland [Haag 2007b]. There are no known public uses of the water, except for irrigation at the PBCC [USACE 2004].

Stream flows are not measured in the Plum Brook watershed, but average flows have been estimated using techniques develope d by the US Geological Survey [Haag 2007b]

5. As would be expected, the flow increases as one proceeds downstream from the PBRF to Sandusky Bay. Average estimated annual stream flows at key stream junctures are:

3.3 CFS, where a small tributary empties into Plum Brook just south of US Rt. 2. 5.5 CFS at US Rt. 6 where the upper flood plain merges into the Stream Mouth wetlands. 4 The water table is defined as the upper boundary or top surface of the zone of saturation in a soil profile or geologic formation. In some cases, subsurface water may be "confined" by impermeable formations surrounding the water-bearing zone and the water level will rise above the confined layer when it is penetrated by a tightly cased well. The term "potentiometric surface" is used to designate the level to which the water rises above its nominal level in a cased well or other constriction. In an unconfined aquifer, the potentiometric surface is the water table [OSU 2008]. 5 This method is based on the following assumptions: 1) the main water source is precipitation surface runoff, 2) there are no significant other sources such as groundwater (springs) or man-produced sources (storm drains or other outfalls - there are some storm drains, but these are not considered to be significant sources under normal flow conditions), 3) there is no significant loss to the underlying water table and 4) that the natural surface runoff patterns in the watershed have not been significantly altered. Also note that the estimated flows are annual averages and significant variation occurs with seasonal precipitation patterns. The upper stream sections (from its origin south of the PBRF to near Bogart Rd.) exhibit intermittent flow [NASA 1959].

TBD-08-006 Page 21 of 56, Rev. 0 Under normal flow conditions, stream channel cross sections at water level in the meandering sections range from two or three feet up to about 10 feet in width. Stream average water depth is typically one foot or less, but the stream depth in a typical meander will vary from several inches deep at the inner radius (point bar) to one-to-two

feet deep at the outer radius (cut bank). In the meandering sections, the stream banks are steeply pitched and thickly vegetated with natural growth vines, bushes and trees. The vertical distance from the water course to the bank tops is approximately 4 to 6 feet under normal flow conditions. Most of the banks along the section extending from Route 2 north to the PBCC are heavily overgrown. However, in the residential area between US Route 2 and the PBCC, the stream banks are la ndscaped at several st reamside residences.

North of the PBCC, the stream flood plain and estuary surface features are quite different from the meandering sections. The present stre am channel is considerably wider and the stream banks are much less pronounced. The water depth at mid-stream increases from about two feet to four feet (in "scoured areas") at the US 6 highway bridge to 4 to 5 feet (or more) at the stream mouth in the Plum Brook estuary. Wetland with marsh vegetation extends several hundred feet from the stream on either side. 5.4 Land Use Land use in the Plum Brook watershed is characterized as suburban low-to-medium density development. Land use is controlled by local zoning. Division of the Plum Brook watershed into zoning categories is shown in Table 1.

Table 1, Plum Brook Watershed Zoning (from PBRF to Sandusky Bay) Zoning Category Area Residential Agricultural Commercial Government-Municipal Recreational Square Miles 0.56 0.3 0.21 0.19 0.36 Acres 361 191 134 120 230 Fraction of total watershed area 0.35 0.18 0.13 0.12 0.22 Table 1 Note. Areas of the watershed zoning apportionment were calculated from electronic property tax maps maintained by the Erie County Auditors Office [Erie 2008]. Thirty five percent of the 1.6 square mile watershed land area, 0.56 square miles, is zoned residential. The resident population density in the Plum Br ook watershed is lower than the Erie County average of 312 persons per square mile and the popul ation density in the immediate vicinity of the stream is much lower. As of late 2006, 42 residences bordered the stream between the PBRF and Sandusky Ba

y. All but two of thes e are located south of the PBCC. Most, if not all of the residences bordering the stream appear to be single

TBD-08-006 Page 22 of 56, Rev. 0 family residences. It is estimated that th e average population density, in the residential areas that border the stream is only 10 to 20 persons per square mile [Case 2007].

Eighteen percent of the waters hed land area, or 0.3 square miles is zoned agricultural. The agricultural land is located between the PBRF and Bogart Rd and north of the Plum Brook Country Club. There are only two stream-side residences between the PBCC and Sandusky Bay. From examination of satellite photos and tours of the watershed, it is observed that most of the land zoned as agricult ural is planted in row crops or is fallow (2007 growing season). No dairy pastures or commercial-vegetable truck farms are observed in the watershed.

Thirteen percent of the waters hed land area, or 0.21 square miles, is zoned commercial. Most of the commercial-zoned land lies be tween Bogart Road and US Rt. 2. This includes the Milan Ave. (US Rt. 250) crossing (bridge over large culvert) proceeding to just north of US Rt. 2, a stream distance of slightly less than one mile. The commercial properties bordering the stream include motels , a large gas station, restaurants and several small store-front businesses. While no census count data is available for the

commercially zoned area, the occupancy is of a transient nature. The highest average occupancy is estimated to be 50 hours a week for employees of the businesses and none of the employees of these businesses or motel guests are expected to be in proximity to the stream for more than a few minutes per day. Much of the stream that borders commercial properties is lined with riprap, co ncrete channels and is bordered by fences and guard rails. In view of these conditions, public contact with contaminated sediments is highly unlikely in the commercial-zoned areas.

Twelve percent of the watershed land area, or 0.19 square miles is zoned government (mostly municipal). All of this property li es between the PBRF north boundary and Rt. 2. This land includes a school bus maintena nce facility and parking lot, a school administrative building, the site of a former sewage treatment plant and the US Rt. 2 highway right-of-way. None of the occupied buildings are in close proximity to the stream (all are more than 200 ft distant).

Twenty two percent, or 0.36 square mile (230 acres) of the watershed land area is zoned

recreational. About 140 acres of this land area is occupied by the Plum Brook Country Club, which is traversed by the stream. The stream crosses several fairways and the maintenance-storage area. Three ponds that at one time were connected to the Plum Brook are located on the PBCC. A small pond is located on the golf course and two larger ponds are located near the maintenance and storage area in the northwest portion of the PBCC. The Plum Brook within the Count ry Club is accessible by employees and recreational golfers.

The remainder of the watershed zoned as recr eational, about 70 acres north of US Rt. 6, lies within the Putnam Nature Preserve, ow ned by the Erie Metro Park district. The portion of the Preserve occupied by the Plum Brook flood plain and wetlands is undeveloped and public access is limited for portions of the year because it is protected

TBD-08-006 Page 23 of 56, Rev. 0 species habitat. Access to about 50% of the area has been restricted for about six months of the year due to Bald Eagle nesting [Haag 2008d]. 5.5 Stream Sections for Exposure Scenarios For the dose assessment, the Plum Brook is di vided into four sect ions. This division considers stream hydrologic characteristics a nd land use patterns. The division is chosen to match stream characteristics with land use patterns to construct the exposure scenarios. The four stream sections are summarized in Table 2. They are identified as:

1. Upper Stream - from Plum Brook Reactor Facility to State Route 2

2. Lower Stream - from State Route 2 to the approximate center of the Plum Brook Country Club property

3. Upper Flood Plain - from Plum Bro ok Country Club to US Route 6

4. Lower Flood Plain and estuary - fr om US Route 6 to Sandusky Bay.

Section 1 encompasses the larges t land area in the watershed, about 0.7 square miles. It is zoned 30% residential, 30 % agricultural, 30% commercial and 10% Government (Municipal). The stream passes through the largest commercial zoned area in the watershed, the commercial strip along Milan Avenue (US 250) between Bogart Rd and Rt. 2. The stream course in this commercial strip, about 0.5 miles in length, has been altered considerably by culver ts, underpasses and retaining walls. The residential zoned portion has the highest potential for members of the public to come in contact with contaminated sediments in this stream section. There are 15 residences adjacent to the

TBD-08-006 Page 24 of 56, Rev. 0 Plum Brook in this stream sec tion. Most of the residences are located between the PBRF northern boundary and Bogart Road, a distance of about one mile. The residences are typically modest ranch homes, a few of which are located fairly close to the stream. Several of these properties include small ve getable and flower gardens. As discussed above, the remainder of the watershed in th is section is agricultural, commercial and municipal government and offers minimal opportunities for contact with Plum Brook sediments by members of the public.

Section 2, lies between Rt. 2 and the mid-portion of the PBCC and encompasses a stream course distance of about one mile. It comprises the lower stream meander hydrologic regime. The surrounding watershed of this section is 0.59 square miles. It is zoned 60% residential, 20% Government (municipal) and 20% commercial-recreational (country club). There are about 25 stream-side residences (houses located within 50 to 150 feet of the stream) between Rt. 2 and the PBCC. Several of these homes are on lots that encompass the stream and the stream banks are landscaped. No vegetable gardens are observed in residential properties bordering the stream (som e have flower gardens). As discussed below, several of these homes are located on lots impacted by stream flood events, particularly the flood of 1969. Most of the homes were constructed after 1969. It is noted that the watershed area encompassed by this section contai ns the highest housing density of the entire watershed, even though the streamside housing density is low.

Section 3 comprises 0.85 miles of the stream course and 0.22 square miles of watershed. It includes the northern half of the PBCC and the upper floo d plain below US Rt. 6, is zoned 60% commercial-recreational and 40% ag ricultural. It contains two residences, located north of the PBCC. Occupancy of areas potentially impacted by contaminated sediments is predominately recreational use (golf)) and PBCC main tenance activities.

Section 4, the lower flood plain-stream mouth is located between US Rt. 6 and Sandusky Bay. It encompasses about 1/2 mile of the stream course and a watershed area of 0.11 square miles (70 acres). It is zoned 100% recreational with public access controlled by the Erie Metro Parks. The width of the stream increases and the width of the watershed - drainage area decreases as the stream approaches Sandusky Bay. 5.6 Sediment Characteristics Cesium-137 has been measured in Plum Brook sediments along the watercourse from the PBRF to Sandusky bay. This section summarizes what is currently known about the distribution of contaminated sediments. It is a summary of the detailed description of sediment characteristics in the compani on radiological characte rization report [NASA 2009]. Cesium-137 and other radionuclides were released from the PBRF via the facility liquid effluent pathway to the Pentolite Ditch

7. The cesium, mostly in soluble form when 7 A review of radioactivity releases from the Plum Brook Reactor Facility in liquid effluents to the Pentolite Ditch during the period of operation from 1963 to 1973 was conducted in 2006 [Crooks 2006]. From this review, it is estimated that a total of between 5 and 7.2 millicuries of Cs-137 were released. While the discussion focuses on the

TBD-08-006 Page 25 of 56, Rev. 0

released to the Pentolite Ditch, was believe d to rapidly adsorb onto suspended clay sediment particles in the ditch. From Pentolite Ditch, it was transported downstream in the form of suspended solid particulates [Crooks 2006, Haag 2007a]. Over time, contaminated sediments were transported to the Plum Brook estuary and into Sandusky Bay where it was deposited in bottom sediments.

Sediments in the Plum Brook comprise a mixture of particles derived from the surrounding soils and the formations through which the stream passes. It includes silt, sand, clays and organic particulates. They range in size from a few 10's of microns in diameter (silts and clay fines) up to several millimeters in diameter (sands). In the stream mouth and lower flood plain, sediment layers are deposited on or adjacent to peat deposits. The movement of Cs-137 adsorbed onto clay sediments is controlled by physical processes. The Cs-137 is predominantly associated with smaller sediment clay size fractions and its movement is controlled by fine sediment transport [Perk 2002].

Sediment transport and deposition in the Plum Brook is a complex process strongly affected by stream flow conditions. Deposition and transport in the meandering stream sections is controlled by changes in stream velocity. This process dominates during normal flow conditions when the stream is c onfined to the channel. During periods of high flow, but at less than flood conditions, sediment is deposited onto the stream banks. It is also resuspended from previous deposits and carried downstream. Under flood conditions, large scale suspension and redist ribution of sediment occurs. Sediment deposits are laid down adjacent to the stream banks and beyond, depending on the magnitude of the flooding. When major floods occur, backwaters are created which slowly recede, leaving sediment deposits at some distance from the stream.

It is important for dose assessment purposes to consider the "fate" or long-term behavior of radionuclides released from the PBRF to the Plum Brook environs. As indicated above, Cs-137 was rapidly adsorbed onto clay mineral particles once the Cs-137-bearing water effluent was released to the Pentolite Ditch. This waterway was constructed as an open excavation six to eight feet deep. Even though the soils on the Plum Brook Facility have been highly disturbed over time by va rious construction activ ities [USACE 2004], the native soils include an abundance of clay minerals identified as illites [USDA 2006]. This type of clay strongly binds Cs-137 in a nearly irreversible manner [Perk 2002]. Over time the contaminated sediments tend to be covered with "new" sediments which are continually added to the stream through soil erosion. The buried sediments are a sink for the Cs-137 and Co-60 which become less available with time for transfer to environmental pathways.

A significant effort was made by NASA for the radiological characterization of Plum Brook sediments. Samples of sediment were collected from 900 locations along the 4 behavior of cesium-bearing sediments, the fate and transport of Co-60 is also of interest. In general, Co-60 behaves similarly to Cs-137 in aquatic environments; it is strongly associated with mineral sediments [Eisen 1997].

TBD-08-006 Page 26 of 56, Rev. 0 mile stream course from Pentolite Ditch at the PBRF and extending into Sandusky Bay. Cores were collected at each location to provide for determination of radionuclide concentration vs. depth. Over 3100 sub-samples (aliquots) from these cores were analyzed by gamma spectroscopy. Characteristics of the Cs-137-bearing sediments are summarized in Table 3. As seen in the table, Cs-137 concentrations are distributed non-uniformly along the stream from the PBRF to Sandusky Bay. Highest maximum and average concentrations are observed in the proximity of the PBRF and tend to decrease with distance from the PBRF.

Table 3 Notes.

1. The precision of measured concentration with depth is limited by the length of core sections used; typically (0 to 6 in and then 12 in. increments below 6 in.).

2. In the table, the minimum concentration reported is the MDA (minimum detectable activity concentration) when less than 100 % of samples are > MDA. For analysis of Cs-137 in soil and sediment samples under typical counting procedures, the MDA is ~ 0.02 to 0.08 pCi/g and for Co-60 it is ~ 0.05 to 0.2 pCi/g.

3. The estimated average concentrations reported in the table are averages of samples collected from locations selected from a systematic sampling plan, usually with a randomly selected starting point. The averages include results from all depths.

TBD-08-006 Page 28 of 56, Rev. 0 As indicated above, the samples collected in the 2005 - 2007 characterization survey were analyzed by gamma spectroscopy and Co-60 was detected in addition to Cs-137 (no other man-made gamma emitting radionuclides were detected). Cobalt-60 was measured above minimum detection levels in 7% of the samples. The fraction of both Cs-137 and Co-60 "detects" (sample concentration >MDA) decreased with distance downstream from the PBRF. To illustrate, Cs-137 was measured >MDA in 90% of the samples collected from stream sections 1 and 2 and in 42% of samp les collected north of the Plum Brook Country Club (flood plain, stream mouth and Bay). Cobalt-60 was measured in 11% of the samples collected between the PBRF and the PBCC and in only 1% of samples collected north of the PBCC. The overall average concentration of Co-60 is 0.076 pCi/g (the maximum concentration measured was 1.7 pCi/g). No significant difference in the average concentration was observed versus downstream distance from the PBRF. Nor was any

consistent relation observed between Co-60 and Cs-137 concentrations (activity ratios) in individual samples or in samples grouped by stream section. Examination of Co-60 concentrations versus depth shows that most of the Co-60 is associated with sediments at depths greater than 6 inches. Sediment samples were also sent to a vendor laboratory for gamma spectroscopic and analysis for tritium, Sr-90 and isotopic uranium. They were selected to represent the entire stream course. The samples included a sample from the Pentolite Ditch, the Plum Brook near Columbus Avenue (stream section 1) and Plum Brook near US Rt. 6 (stream section 3). Only uranium was detected above environmental MDA levels, but at concen trations consistent with background concentrations [STA 2005].

5.7 Impact of Fallout Cesium-137 Cesium-137 (and other long-lived radionuclides including, H-3, C-14 and Sr-90) have been deposited world-wide from nucl ear weapons fallout. A large fraction of Cs-137 bomb-debris was injected into the upper atmosphere from above-ground weapons tests. The Cs-137

attached to particulates and aerosols which circulated in the upper atmo sphere and eventually deposited on the surface of the earth; most was carried down in rainfall. A total of 26 million Curies of Cs-137 was produced by atmosphe ric weapons tests [Beck 2002]. Most was deposited in the northern hemisphere between 1949 and the mid 1960's. The 1986 Chernobyl reactor accident in the Ukraine released considerable Cs-137 as well (about 2.3 million curies), but most was deposited in Eur ope and the European Artic [Izrael 2007].

Cumulative Cs-137 deposition on the earth's surface at the latitude corresponding to Sandusky, OH (40 ºN) was approximately 140 millicuries per km 2 (360 mCi/mi

2) [NCRP 2006]. This equates to approximately 2.3 curies deposited on the entire Plum Brook watershed and 590 millicuries deposited on the 1.6 mi 2 area Plum Brook watershed impacted by Cs-137 from the PBRF. Most of this deposition occurred by the mid-1960's; more than

TBD-08-006 Page 29 of 56, Rev. 0

one Cs-137 half-life has since elapsed. None-the-less, a signifi cant Cs-137 inventory from fallout deposition remains in the watershed. 8 The Cs-137 deposited from fallout rapidly become s attached to clay and organic particles in the soil and becomes "essentially non-exchang eable" [Ritchie 1990]. Over 95% of fallout Cs-137 deposited on land surface is retained in undisturbed soil and sediments [NCRP 2006]. Movement of Cs-137 in the environment is primarily governed by physical processes, mainly related to fine-sediment transport [Perk 2002].The fate of locally deposited fallout Cs-137 is highly dependent on soil type, land use and precipitation. In temperate climates with soil types of northern Ohio, the Cs-137 inventor y is largely divided between the soil and sediments deposited in waterways. 9 Cesium -137 deposited on soil gradually moves downward in the soil column through leaching and precipitation at lower depths. In

agricultural areas, relatively uniform mixing of Cs-137 occurs to the depth of plowing or tilling, whereas in undisturbed land, the concentration decreases with depth. Cesium-137 in near-surface soil is also continually removed as soil particles are entrained and moved by surface water runoff and erosion. Over time, the waterborne Cs-137 bearing sediments are

transported downstream [Ritchie 1990]. The fallout Cs-137 deposited on the 6 square mile Plum Brook watershed is by far the major source of the current Cs-137 inventory in the flood plain and estuary.

Information on fallout Cs-137 concentrations in northern Ohio freshwater sediments is available from several research studies. Radionuclides in the environment, including Cs-137, Be-7 and Pb-210, are used to "measure" soil erosion and sediment transport. Recent studies provide information on current levels of Cs-137 in freshwater sediments in the vicinity of Sandusky. Ketterer and Matisoff reported Cs-137 concentrations in Old Woman Creek and its estuary at Lake Erie, about 15 miles east of Sandusky Bay [Kett 2002, Matis 2002]. A maximum concentration of 0.5 pCi/g was measured in undisturbed near-surface soil (at 7 cm depth in an island on the creek). Concentrations of up to1.3 pCi/g were measured in sediment deposits in the estuary (at a depth of 20 cm). Bernal recently measured Cs-137 concentrations from 3 to 8.8 pCi/g in Old Woman Creek estuary sediments [Bernal 2008]. In a study of sedimentation in a nearby reservoir (Ballv ille Dam on the Sandusky River, near Fremont, OH), Cs-137 concentrations of up to 6 pCi/g (at 30 cm depth) were reported [Evans 2002]. Everyone receives radiation exposure from fallout radionuclides in the environment. Exposure to fallout Cs-137 curren tly constitutes the largest co mponent of the average annual dose from fallout radionuclides in the US. However, it is a small fraction of the average annual dose received by individuals from background radiation, medical uses and other 8 The fallout deposition of Cs-137 in the 40 to 50 ºN latitude region resulted in an average concentration in soil of 0.7 pCi/g (0 to 15 cm depth) in the mid-1960's [NCRP 2006]. This translates to an average concentration of about 0.26 pCi/g at present and constitutes the source of Cs-137 that is readily measured as "background" in most soil. 9 When fallout Cs-137 is initially deposited in areas with growing vegetation, including livestock fodder (foliar deposition), a significant fraction may enter the food chain and result in dose to humans from consumption of contaminated milk and other foodstuffs. However, the fraction of the total environmental inventory that is in the terrestrial food chain rapidly decreases over time, after the initial growing season, as the uptake by plants from the soil is limited [NCRP 2006].

TBD-08-006 Page 30 of 56, Rev. 0 sources. The average dose to individuals in the US from all sources of radiation is about 360 mrem per year [NCRP 1987]. The estimated a nnual average dose to individuals (adults) in the US from Cs-137 was approximately 8 mrem in 1965. It had declined to about 0.5 mrem in 2000 [Bouv 2002].

5.8 Exposure Scenarios

Four exposure scenarios are established for the dose assessment. They are: Suburban Gardener, Brook-side Resident, Country Club Ma intenance Worker and Recreationist. Each scenario was developed by matching Plum Brook stream-environment characteristics with land use most representative of each section of the Plum Brook watershed. It should be noted

that while the exposure scenarios are considerably more represen tative of potential exposure conditions than the generic resident farmer scenario, they still involve conservative assumptions. To illustrate, occupancy time is found to be the parameter that most influences the calculated dose in three of the four scenarios. Most areas of the Plum Brook are inhospitable and difficult to access, with the exception of the Plum Brook Country Club golf course. In the absence of detailed information on human contact with contaminated Plum Brook sediments, occupancy factors from NRC studies of postulated scenarios for urban contaminated sites are used. The exposure scenarios are summarized in Table 4. Table 4, Scenario Summary Scenario Title Plum Brook Stream Section Dose Receptor Source Pathways Suburban Gardener Upper Stream

The Suburban Gardener scenario is suggested by the observation that several residences along the upper meandering stream section (between PBRF and Rt. 2) have gardens. It is assumed that the garden is located on near the stream bank and the garden soil was supplemented by sediment excavated by the resident from the banks of Plum Brook. The garden is assumed to be 186 m 2 (about 45 x 45 ft.)

10. The Suburban Gardener exposure pathways include direct exposure while wo rking in the garden (123 hours per year), ingestion of Cs-137 and Co-60 from eating ve getables grown in the garden, direct soil ingestion and inhalation. The contaminated sediment is mixed with uncontaminated soil by tilling. A conservative assumption is that the contaminated soil-sediment mixture lies on the surface of the garden in a three inch thick layer. The Suburban Gardner scenario is illustrated in Figure 3.

The Brookside Resident scenario is suggested by the observation that some houses in the lower stream meander section were construc ted after the 1969 flood event and are located near the stream. In this scenario it is assumed that a home was constructed on land where contaminated sediments were deposited. It is also assumed that the home is situated on an area of contaminated sediment that extends partially beneath the house. The house is assumed to have a 2000 ft 2 (186 m 2) footprint and the contaminated zone is 45.6 m 2 in area. The exposure pathways are direct exposur e to a resident inside the house (attenuated

by the house-structure), direct exposure to contaminated sediments outside the house (lawn mowing and landscaping maintenance), ingestion of contaminated soil and inhalation of suspended sediment (dust). 11 The resident is assumed to spend 1096 hours per year in the portion of the house located on contaminated sediment and 80 hours a year on the contaminated portion of the outdoor property. See Figure 4 for a schematic of the

Brookside Resident scenario. The Country Club Maintenance worker is base d on the observation that soil containing sediment from Plum Brook has been used as landscaping fill on the Plum Brook Country Club golf course. This material was taken from spoil piles that were excavated from two ponds impacted by contaminated sediments. These ponds were at one time connected to Plum Brook. They are currently used to store water pumped from the book for irrigating the golf course. It is assumed that contaminated sediment was used to fill-in an area 3 meters wide on either side of a golf cart path that extends for 100 meters. The sediment is in a three-inch thick layer on the surface and the maintenance worker spends an average of 15 hours a week during the 30 week gol fing season traveling along the path and performing landscape maintenance along the pathway. 12 The Country Club Maintenance worker scenario is illustrated by the schematic in Figure 5. 10 This is the area of the garden used in a sample problem evaluated by the NRC in NUREG/CR-5512 for a residential exposure scenario [USNRC 2001]. It is assumed that enough material was excavated to establish a three-inch layer of garden surface soil/sediment. This amount of material constitutes 18.5 cubic yards; a medium-sized dump truck load, 11 The area of the house and the area of the contaminated soil beneath the house correspond to those used in a sample problem evaluated by the NRC in NUREG/CR-5512 [NRC 2001].

12 The volume of soil/sediment assumed to be placed along the cart path constitutes 60 cubic yards.

TBD-08-006 Page 32 of 56, Rev. 0

The Recreationist scenario was developed to represent occupancy and exposure of a member of the public in the stream-mouth estuary. This individual is assumed to be exposed from direct radiation, inhalation and direct ingestion of contaminated sediments while walking and standing on the contaminated stream bank and alluvial deposits in the adjacent wetlands. The Recreationist is assumed to be a fisherman who spends about 10 hours a week for 10 weeks each year in the stream. He or she consumes game fish caught in the Plum Brook stream mouth. 13 The contaminated zone is assumed to be a band of sediment 1500 m 2 in area that underlies the stream bank in an area that is accessible to the public just north of the Rt. 6 overpass. The Recreationist scenario setting and pathways are illustrated in Figure 6. The size of the contaminated zone was established considering characterization information and the calculated Cs-137 inventory associated with contaminated zones of different sizes. Th is is discussed in Section 6.4, Sensitivity Analysis.

6.0 Dose Calculations with RESRAD

This section describes preparation and performance of dose calculations with RESRAD, Version 6.4, for the four exposure scenarios described in the previous section. This constitutes the following:

Selection of dose pathways Source term abstraction Establishing parameter values Sensitivity analysis Setup and performance of RESRAD case runs.

While outlined here as a series of steps, the dose assessment is actually an iterative process. This has required modifications to some of the initial assumptions and parameter values along the way. What is described here represents the fi nal setup used with RESRAD for the dose results reported in Section 7. 6.1 Pathway Selection

As described in Section 3.0, and illustrated in Figure 1, the RESRAD code has provisions for calculating doses to an individual from eight exposure pathways. Pathways for the present dose assessment have been established based on the Plum Brook conceptual site model and exposure scenarios as described in Section 5.0. The eight exposure pathways of RESRAD have been reduced to five that are applicable. They are: 13 A fisheries biologist was consulted who is familiar with the Lake Erie south shore and Sandusky Bay regional fishery habitat. Game fish enter Sandusky Bay each season and may occasionally enter the Plum Brook estuary. However the estuary is not a preferred habitat or a spawning ground. Fish typically found in the estuary and upper flood plain include carp and various minnows [Weimer 2008].

TBD-08-006 Page 33 of 56, Rev. 0 Direct exposure from radioactivity contamination in the ground (soil or sediments) Consumption of produce grown in contaminated soil Consumption of contaminated fish caught in nearby surface water Ingestion of trace quantities of contaminated soil or sediment Inhalation of airborne contamination suspended from contaminated surface soil or sediment.

The remaining RESRAD pathways: drinking water from a local well in contact with contaminated water, consumption of meat products from domestic animals fed with fodder grown on contaminated soil and radon inhalation are eliminated. No domestic water supply wells are identified in vicinity of the Plum Brook. 14 All residences and businesses in the Plum Brook watershed obtain domestic water from municipal water supplies, primarily from Lake Erie [OSU 1998]. While several farms are identified in the Plum Brook watershed, all of the land zoned for agricultural use that borders the Plum Brook is either fallow or plante d in row crops. None of the residences bordering the Plum Brook are on land that is zoned agricultural. Hence, the meat consumption pathway is not credible. Finally, the radon inhalation pathway is eliminated because radon precursors (uranium or radium) are not among the radionuclides that have been measured in PBRF liquid effluents, the original source of contamination in the sediments [NASA 2009]. The dose pathways that apply to each of the expos ure scenarios are identified in Table 5.

14 The primary ground water resource in Erie County is in the thick bedded limestone deposits that underlie the region (see Section 5.2). However, most of this resource has been impacted by underground disposal of storm wastewaters from nearby communities and is not considered acceptable for public us e [OSU 1998].

TBD-08-006 Page 34 of 56, Rev. 0 6.2 Source Term Abstraction

Results of the radiological characterization of Plum Brook sediments and the features of RESRAD are considered in developing source terms. Characterization results show that Cs-137 (and Co-60) contamination of PBRF origin are not distributed uniformly or continuously along the Plum Brook but tend to be located in small areas or "pockets" on a horizontal scale of about one meter (or less) in the stream meander sections and in larger lens-shaped deposits in areas impact ed by flood backwaters, the flood plain and estuary [NASA 2009]. Areas w ith detectable activity typically exhibit non-uniform vertical distribution. Often, the highest concentrations are found in subsurface layers.

The RESRAD code is designed to calculate doses from radioactive material uniformly distributed in a layer of soil called the "contaminated zone." This can be modeled as either a circular disk (cylinder) or as a polygon. The thickn ess and area can be varied without practical limits, but the dimensions are constant for a given case. It can be modeled as a surface layer or as a subsurface layer overlain by an uncontaminated covering soil layer of specified th ickness (the cover zone) [ANL 2001].

In view of the non-uniform distribution of contaminated sediments, source term models are developed comprised of multiple components. Source terms are modeled as a combination of volume sources of uniform contaminant concentration. 15 Each RESRAD case is limited to one source volume. Source terms with more than one source volume are implemented via multiple case runs. The operating assumption is that the doses are

additive; the total scenario dose is obtained as the sum of doses from individual source term elements. This is not always the case as discussed below. Scenario-specific source term models are developed. The source term models are summarized in Table 6.

(4) 15 Doses are calculated by RESRAD for each source term element with a input concentration of 1 pCi/g for a single radionuclide The scenario doses are then calculated with Microsoft EXCEL using the estimated concentrations of Cs-137 and Co-60 in each source term component.

Table 6 Notes:

1. The plant food pathway is suppressed for the Suburban Gardner local area elevated activity source dose calculation. It is assumed to be located on the nearby stream bank outside of the garden.

2. The local elevated area source is as described for Cs-137. No elevated area source is used for the Co-60 dose calculation. It is not assumed to be present in the Plum Brook flood plain [NASA 2009].

3. The principal contaminated zone source model as described is for the Cs-137 direct exposure pathway. For Co-60, a single layer contaminated zone source model is used. As explained in the text, a separate source model consisting of a single layer is used for the Cs-137 fish pathway dose calculation.

4. Modeled as described for the Cs-137 direct exposure pathway. No elevated area Co-60 source is used as only very low levels are measured in estuary sediments. As discussed in the text, a separate source model consisting of a single layer is used for the Cs-137 fish pathway dose calculation.

As seen in Table 6 the source term model for each scenario consists of two source volumes: the principal contaminated zone source and a localized small area source of elevated activity. Depending on the scenario, the sources are composed of either single or multiple layers or strata. Direct pathway doses from multiple sources including multiple layer sources are obtained as the sum of the doses calculated by RESRAD for each source term component. This is an application of the "superposition principle" used extensively in radiation shielding calculations [Shultis 2000].

Separate source term models are developed fo r the Recreationist scen ario direct exposure and fish ingestion pathways for Cs-137 dose calculations. As shown in Figure 7, the direct exposure pathway source term model consists of two source volumes, each composed of three strata. They are the principal contaminated zone source and the local elevated area source. This is the same approach as used for the other scenarios with multi-layer sources.

To provide a conservative estimate of the dose from the fish consumption pathway, the contaminated zone is placed in dire ct contact with the saturated zone. 16 The contaminated zone is placed immediately above the saturated zone by elimina ting the intervening unsaturated zone strata. All the radionuclides released (leached) from the contaminated zone to the saturated zone are transporte d to a nearby well or surface water body [ANL 2001]. For the hydrologic transport calcula tions in this scenario, the RESRAD mass balance model option is used. 17 These special provisions maximize the transport of 16 The conceptual source term model which places the contaminated zone in direct contact with the saturated zone closely simulates the physical setting in the Plum Brook estuary. Here the sediments are in direct contact with the stream and the local water table in the adjacent wetlands is at the same elevation as the surface water. 17 Use of the mass balance option was recommended by the ANL-EAD RESRAD team [Gnan 2008].

TBD-08-006 Page 36 of 56, Rev. 0 contaminants to the groundwater and hence to the Plum Brook surface water where it enters the aquatic food chain and is taken up by fish.

Modeling the source term for the fish consumption pathway as multiple-layer sources

was abandoned as it causes conflicts with competing requirements. The spatial relationship between multi-layer source elements cannot be preserved if each element is placed in contact with the saturated zone to maximize contaminant transport. To avoid this issue, the principal contaminated zone and local elevated area sources are modeled as

single-layer sources of 30 in. thickness. 18 The Recreationist scenario fish consumption pathway Cs-137 source term and hydrologic model are illustrated in Figure 8.

Sediment samples from the Plum Brook flood plain and estuary yielded a low frequency of Co-60 detection (~ 1%) measured at very low concentra tions [NASA 2009]. The characterization data does not suggest a multiple-layer Co-60 source term model. The Recreationist Scenario dose calculations for Co-60 can be accomplished using a source term model comprised of a single layer contaminated zone source. The conceptual source term and hydrologic transport model for Recreati onist scenario is illu strated in Figure 9. Uncertainties that attend the source term models adopted for this dose assessment contribute to the uncertainties in calculated doses. These arise from two main causes: inherent uncertainties in the RESRAD model and uncertainties in the source term descriptions. A separate source of uncertainty, model parameter uncertainty, is discussed in Section 6.4, Sensitivity Analysis). The RESRAD model and similar environmental radiological assessment models require that complex environmental settings be reduced to compartments of uniform characteristics with constant rate transfer processes. The first cause, model uncertainty, is outside the scope of this discussion, but it should be recognized as a contributor. Its' effect is difficult to quantif y, other than to state that it causes the magnitude of uncertainties in calculated doses to be underestimated.

Uncertainties in source terms arise from va riations in the physical distribution of contaminated sediments, the radionuclid es present at any location and their concentrations. These uncertainties are discussed in Section 5.6, Sediment Characteristics, and in the Plum Brook characterization report [NASA 2009]. 18 To obtain doses in mrem/y, the dose from unit radionuclide concentration (mrem/y per pCi/g) is multiplied by the estimated activity concentration of each source volume. The source volume concentration for the primary contaminated zone Cs-137 single-layer source is estimated as the average concentration in the 0 to 30 in. depth. The source volume concentration for the Cs-137 local elevated area single-layer source is estimated as the average of the maximum concentrations in the 0 to 30 in. depth layers [NASA 2009]

This section describes the sensitivity and uncertainty analysis. The first objective is to identify the RESRAD model parameters that have the most significant effect on the calculated doses. In this context "sensitivity" is defined as "the degree to which model outputs are affected by changes in input values". 19 The second objective is to obtain uncertainty estimates for calculated doses. Th e sensitivity and uncertainty analysis is described in detail in Appendix F. A summary is provided here.

A "screening analysis" is performed to identify the most sensitive parameters. First, the

most significant pathway contributors to dose are identified. This is accomplished by calculating doses from unit concentration (1pCi/g) of Cs-137 and Co-60 for each scenario using the parameter values developed in Appendix D. Then the total scenario and

pathway doses for each radionuclide are calculated using the concentrations of each radionuclide from the recent characteriza tion report [NASA 2009]. The results are evaluated to obtain a ranking of the pathways, based on their relative contribution to total scenario dose. The results are shown in Table 13. The ta ble shows that the direct exposure (ground) pathway is the domi nant pathway in all scenarios.

1. The pathway doses listed here may not be in exact agreement with those reported in Section 7 as the sensitivity analyses were conducted prior to some of the final dose assessment

RESRAD case runs.

2. Pathways are ranked by the ratio (fraction): pathway dose ÷ maximum pathway dose (Brookside Resident ground pathway dose from Cs-137).

The next step in the screening analysis is to screen input parameters, focusing on the most dose-significant pathways identified in Table 13. Principal parameters for each pathway in the four scenarios are identified in Section 6.3. The RESRAD sensitivity analysis capability is used to perform a comprehensive screening of the input parameters for two representative exposure scenar ios: the Suburban Gardner an d Recreationist scenarios. They represent all the pathways considered in the dose assessment: direct exposure to ground source, ingestion of garden vegetables, ingestion of fish, inhalation of suspended sediment-dust and direct ingestion of contaminated sediment. Sensitivity analysis reports are generated for each parameter. Non-significant input variables (parameters) are identified and eliminated from further consideration. Then, the parameters that show sensitivity effects are identif ied and ranked. Table 14 shows th e results of the sensitivity ranking for the representative scenarios. The sensitivity index is defined and calculated as described in Appendix F.

1. Parameters are ranked within the Suburban Gardner parameter set.

2. Parameters are ranked within the Recreationist parameter set.

The parameter sensitivity ranking is used as th e starting point for the uncertainty analysis. The main objective is to establish a consistent and reasonable basis for estimation of uncertainties in the doses calculated with RESRAD. By incorporating the parameters with the greatest sensitivity, the main sources of error from parameter uncertainties are included in the calculated doses. 20 The uncertainty analysis was performed using the RESRAD probabilistic mode. From the screenin g results listed in Table 14, a set of key-sensitive parameters was established fo r each scenario. Even though the Brookside Resident and Country Club Maintenance Worker scenarios were not screened directly, only the direct exposure pathway is significan t in these scenarios. The RESRAD direct pathway model parameters identified as sensitive for the Suburban Gardner and Recreationist were assigned to these scenario s for the probabilistic dose calculations in the dose assessment.

The probability sampling distributions assigned to the four scenarios are listed in Tables 15 through 18. The basis for selection of the probabilistic sampling distributions is provided in Appendix F. The parameter sets developed in Appendix D and the sampling distributions developed in Appendix F are then used in the RESRAD case runs for assessment of doses in the probabilistic mode.

20 See Appendix F, Sensitivity Analysis, for additional discussion of uncertainties in calculated doses.

6.5 Case Run Summary The dose assessment results are obtained from the RESRAD case run reports compiled in Appendix B. The appendix includes an index which identifies the run date, case title and

description, the report pages, the input file name and the dose calculation results. Single radionuclide sources of unit concentration were used as input for each source term component for each scenario. Each case was setup with the basic-deterministic mode parameter input values specified in Appendix D. Each case was run in probabilistic mode with input variable sampling distributions and defining parameters specified in Appendix F. The recorded results include deterministic dose, probabilistic dose and uncertainties all in mrem/y per pCi/g for the total dose and ingestion pathways as applicable. 21

21 Precautions are taken to avoid "double counting" of pathway doses for the Recreationist scenario. The Fish ingestion pathway is suppressed for the Cs-137 direct pathway source term model case runs and the direct pathway is suppressed for the fish pathway source term model case runs.

TBD-08-006 Page 45 of 56, Rev. 0 oses 7.0 Results

The RESRAD single radionuclide doses for unit concentration are reported for each component of the scenario source term models in mrem/y per pCi/g. Then the single radionuclide pathway doses in mrem/y for each scenario are calculated by multiplying the unit concentration doses by the radionuclide concentrations of each source term component. The total pathway doses are obtained as the sum of the single radionuclide dose

s. Total scenario doses are obtained as the sum of the total radionuclide pathway doses. Uncertainties in the resultant doses are calculated using standard error propagation formulae.

22 Age-dependent doses were also calculated and these are discussed. The calculated direct pathway doses for each scenario are compared to dmeasured at selected locations along the Plum Brook with thermoluminescence dosimeters and portable radiological survey instruments.

7.1 Dose from Unit Concentration

The calculated RESRAD results in dose per unit concentration for the four scenarios are reported in Tables 19 through 22. The doses are probabilistic results. the peak value of the mean doses (maximum dose is at time zero) and uncertainty as one standard deviation of the mean are reported. The dose calculation results are obtained from the RESRAD case run reports in Appendix B. It is seen that the scenario dose from Co-60 is greater than the dose from Cs-137 for unit activity c oncentrations. However, as discussed in the next section, when the actual (estimated) source term activity concentrations are considered, the dose contribution from Cs-137 greatly exceeds the dose from Co-60.

Doses for each source term component taking into account the source term concentrations are calculated for each scenario. The dose from each radionuclide is calculated as the product of the dose from unit concentration and the source term component concentrations. Total radionuclide doses for each pathway are obtained as the sum of the Cs-137 and Co-60 doses. The total dose for each scenario is then obtained as the sum of the total radionuclide pathway doses. To aid reviewers, the input radionuclide concentrations and results of these calculations are presented below in a pair of tables for each scenario.

Table 23 shows the source term component concentrations and Table 24 shows the calculated doses for the Suburban Gardner scenario. The source term component radionuclide concentrations are obtained from the recent characterization report [NASA 2009]. The total scenario dose is 7.96 +/- 3.87 E-01 mrem and Cs-137 contributes 90% of

TBD-08-006 Page 48 of 56, Rev. 0 the total. The table shows the effect of the local elevated area source components with their high Cs-137 concentrations. The elevated area source term components contribute 93 % of the total scenario dose. The contaminated garden source term contributes 7 % of the total dose and the plant consumption path way contributes only 2 % of the total dose (28% of the total dose from the garden source term component). This result is driven by the conservative assumption that the dose rece ptor is exposed to the elevated activity source 100% of the time that he or she is working in the garden.

The contribution from the elevated activity source is somewhat less relative to the other scenarios because the dose receptor only receives

exposure from this source when he or sh e is out of doors working on the lawn and landscaping. The source is assumed to be lo cated near to, but not underneath the house.

The default parameters for RESRAD models and exposure scenarios are based on adults. Information on the releases to the Plum Brook has been provided by NASA to the public on several occasions and questions have been raised about doses and potential risks to children. What are the effects on the calculated doses if age-dependent values of critical parameters are used to calculate the doses? As a result, NASA has requested that a technical evaluation be performe d to address this issue. An evaluation of age-dependent doses from Plum Brook sediments was conduc ted in 2008 [NASA 2008a]. This report is included as Attachment E and is summarized here.

The US EPA and NRC policy has been that use of an adult as the receptor for dose and risk assessments is generally acceptable and is protective of children [USEPA 1994, USNRC 2003]. Also, US Government-approved age-dependent dose factors were not available when this policy was established. And as a practical matter, no means existed to calculate doses to children using codes such as RESRAD. However, beginning in 1989 the International Commission on Radiological Protection (ICRP) issued age-dependent dose factors for assessment of doses to the public from intake of radionuclides, culminating in the issuance of ICRP Report No. 72 in 1996. [ICRP 1996]. The developers of RESRAD have incorporated ICRP-72 age-dependent dose f actors in version 6.4 of the code released in December 2007 [USDOE 2008]. It is now possible, using RESRAD to

calculate doses to individuals other than adults from exposure to Plum Brook sediments. Doses to members of the public of various age groups who could come into contact with Plum Brook sediments were calculated (age-d ependent doses). Thr ee exposure scenarios were selected to examine the effects of age-dependent dose model parameters and to obtain a reasonable upper-bound estimate of the dose to a chil

d. The highest calculated

TBD-08-006 Page 54 of 56, Rev. 0 dose was 0.13 mrem/y per pCi/g of Cs-137 for a sm all child who is in direct contact with contaminated sediments for 450 hours a year. This could be achieved by a child who

plays outdoors an average of 15 hours a week for 30 weeks a year in an area containing contaminated sediments. This is considered to be a bounding scenario as there are limited opportunities for any significant contact with Plum Brook sediments. The highest calculated dose to a child is less than the highest dose to an adult, 1.7 +/- 1.7 E-01 mrem/y per pCi/g calculated in the dose assessment reported by NASA in June, 2008 [NASA

2008]. 23 Overall, the doses from exposure to individuals from contaminated sediments are not strongly age-dependent. It is concluded that the use of a dults as dose receptors for calculated doses is reasonable for assessmen t of dose and risk. There is no age group

which receives a higher dose than adults.

7.4 Comparison of Calculat ed and Measured Doses

Direct measurements of radiation dose rate s in the vicinity of the Plum Brook were performed for comparison with the calculated doses. Measurements were performed at selected locations along the Plum Brook using Thermoluminescent dosimeters (TLDs) and low-range radiological survey instruments. The TLDs were placed for 15 weeks at

selected locations along the Plumb Brook. Locations were selected to represent exposure scenario settings used in the dose assessment and other locations of interest. These included locations representing typical or average exposure conditions and locations where higher than average concentrations of Cs-137 were measured in Plum Brook sediments. In addition, dose rate measurem ents were taken with low-range survey instruments at each TLD location at time of placement and again at removal. The TLD and survey instrument measurements and th eir results are described in Appendix C.

As discussed in results in the previous sections, the dose assessment predicts that most of the dose is received by the "d irect" exposure pathway. That is, whole body dose due to penetrating gamma radiation emitted from Cs-137 and Co-60 in the sediments. The measurement results are compared to di rect exposure pathway outdoor dose rates calculated using RESRAD results for the f our exposure scenarios. The principal conclusions from the environmental dose measurements are: The 95% upper confidence limit of the doses measured with TLDs are less than the direct pathway doses calculated with RESRAD for all measurement locations except at the location selected to represent the Brookside Resident scenario. In this case the calculated and measured doses are equivalent. 23 The assessment of age-dependent doses [NASA 2008a] was reported in a companion report to the initial dose assessment [NASA 2008]. Calculated age-dependent doses were compared to the adult doses from Cs-137 in the 2008 report.

TBD-08-006 Page 55 of 56, Rev. 0 Identical results are obtained from measurements using an independent method - dose rates measured with microR meters. This comparison shows that measured dose rates are less than calculated dose rates at a ll locations except the Brookside Resident scenario location where measured and calculated dose rates are equivalent. These results confirm that the dose assessment results are conservative.

7.5 Summary and Conclusions

The dose to members of the public from Plum Brook sediments contaminated with Cs-137 and Co-60 was calculated for four exposure scenarios. The scenarios represent conservative assumptions regarding a range of possible conditions whereby members of the public could receive radiation doses from the contaminated sediments. The dose to individuals exposed in the scenarios range from 0.65 to 1.2 mrem/y. The average of the doses to the four scenario receptors is 0.88 +/- 0.22 mrem/y.

This result shows that the dose to an individual is well below the 25 mrem/y dose agreed by the principal stakeholders as being acceptable for Plum Brook areas impacted by contaminated sediments. This conclusion is further supported by measurements of radiation doses at locations on the Plum Brook selected to represent settings similar to those of the exposure scenarios. The measured doses are less than the calculated doses at three of the four locations and comparable to the calculated doses at the fourth location.

Additional perspective is provided by comparison with the dose to the public from Cs-137 fallout from atmospheric weapons testing that remains in the environment. The

annual average dose to individuals in the northern hemisphere from fallout Cs-137 is reported to be about 0.5 mrem/y (with an estimated uncertainty of +/- 100%). Thus, the calculated doses from exposure to Plum Brook sediments are indistinguishable from the "background" dose received from the fallout Cs-137 burden in the Plum Brook watershed.

1.0 Introduction Measurements of radiation dose rates in the vicinity of the Plum Brook were performed using environmental thermoluminescence dosimeters (TLDs) and radiological survey meters. Thermoluminescent dosimeters designed for environmental radiation monitoring were placed for 15 weeks at selected locations along the Plumb Brook. Locations were selected to represent exposure scenario settings used in the dose assessment and other locations of interest. These included locations representing typical or average exposure conditions and locations where

higher than average concentrations of Cs-137 were measured in Plum Brook sediments. Radiological survey measurements were also taken at each TLD location at the time of placement and again at removal.

2.0 Background

The study was designed to complement the dose assessment for Plum Brook sediments. In the dose assessment, estimated doses to individuals are calculated using computer models and assumptions regarding physical, metabolic and behavioral parameter values. The objective of the measurements described herein is to provide independent confirmation of doses from direct radiation that could be received by individuals in the vicinity of the Plum Brook. The assessment of dose to individuals from Plum Brook sediments as reported in the main report, predicts that most of the dose is received by the "direct" exposure pathway. That is, whole body dose due to penetrating gamma radiation emitted from Cs-137 and Co-60 in the sediments.

Characterization surveys show that contaminated sediments are non-uniformly distributed along the Plum Brook [NASA 2009]. Two sources of di rect exposure are evaluated in the dose assessment. The predominant mode of exposure to an individual in the immediate vicinity of Plum Brook is long term exposure to low average concentrations. In the dose assessment, this is modeled as the contaminated zone. There is also th e possibility of contact with localized areas of elevated contamination from 50 to about 75 times the average concentrat ion. These are modeled as localized sources of elevated activity.

Measurements of gamma radiation dose and dose rates in locations impacted by contaminated sediments are performed with environmental TLDs and with survey instruments. 1 The expected range of outdoor dose rates in sediment-impacted locations, as determined by the dose assessment, is examined. Table 1 shows the doses calculated using RESRAD results converted to equivalent outdoor dose rates. The calc ulated outdoor dose rates range from 1.1 µrem/h at the Brookside Resident scenario property to 6.3 µrem/h in the immediate vi cinity of the Suburban Gardner scenario garden. Survey instruments used for confirmatory measurements must be capable of measuring net dose rates (above typi cal local background dose ra tes) in this range. 1 The survey instruments used for this study, Ludlum Model 10 microR meters, are calibrated and maintained in accordance with PBRF Instrument Procedures. This includes daily source-performance checks.

TBD-08-006, Appendix C Page 5 of 55, Rev 0 Low-range gamma and x-ray survey instruments are capable of measuring dose rates as low as a few µR (or µrem) per hour. 2 Environmental TLDs are capable of measuring integrated doses as low as approximately 5 mR [Mirion 2008]. The calculated integrated doses fo r 106-day exposures are also shown in Table 1. They range from 2.81 mrem (Brookside Resident) to 16.12 mrem (Suburban Gardner).

1. Scenario exposure hours are obtained from Section 5.6 of the main report.

2. Outdoor exposure rates are calculated as the quotient: total direct dose ÷ exposure hours (with units conversion). The uncertainty is estimated by error propagation.

3. The integrated dose is calculated for an exposure period of 2542 hours, the average duration of the TLD field-exposure in the present study.

2 The Ludlum Model 19 micro R Meter has a lower limit of detectability (LLD) of approximately 4.5 µR/h (fast response) and approximately 2 µR/h (slow response) [LMI 2009]. In this report, measurements of environmental gamma radiation doses and dose rates may be reported in units of Roentgens (R) or rem. For the purposes of this discussion they are considered equal (1R ~ 0.95 rem) [Turner 1995].

TBD-08-006, Appendix C Page 7 of 55, Rev 0 4.0 Dosimeters Standard environmental thermoluminescence dosimeters supplied by Global Dosimetry Solutions, Inc. were used for the measurements. 3 The dosimeters are manufactured by Panasonic. Each dosimeter is a three-element packet (or badge) comprised of one lithium borate (Li 2 B 4 O 7 , doped with copper) and two calcium sulfate (CaS0 4, doped with thulium) TLD chips (elements). The dosimeters are capable of measuring integrated doses from 5 to 5,000 mrem [Mirion 2008]. Representative dosimeters of similar specification have been "performance tested" against applicable performance standards [Prox 2001]. The vendor also maintains accreditation by the National Institutes of Standards and Technology National Laboratory Accreditation Program (NVLAP). The current NVLAP certificate is provided in Attachment Dose measurement results are reported in mR (m illiroentgen) as the average of the individual element doses. The total uncertainty in the reported dose for each TLD element is 26.4% [Cords 2008]. Dosimeters were mounted on steel posts for placement in the field. The posts were inserted into the ground adjacent to the stream. Each "station" consiste d of two TLD packOne dosimeter was attached at a height of one meter with a second dosimeter attached at a heightof 2/3 meter from ground surface. A dosimeter station mock-up is shown in Figure 1. The onemeter TLD was placed for measurement of the dose at the dose receptor point for a typical adultThe 2/3 meter TLD was placed to correspond to the dose receptor point for a 10 to 12 y C. . . ld hild.

5.0 Placement and Retrieval of Dosimeters Dosimeters were placed in two areas identified as the "study area" and the "background area". The study area includes selected locations downstream of the PBRF water effluent monitoring station (WEMS) at the Pentolite Ditch. The placement locations for the study area and background area TLD stations are shown on local area maps in Figures 2 and 3. All but one of the study area TLDs stations were placed in areas accessible to the public that are potentially impacted by contamination of PBRF origin. One was placed outside the main study area adjacent to the Pentolite Ditch just below the WEMS outfall, on NASA property. A Cs-137 concentration of 1000 pCi/g was measured at th is location in 2005. A station was placed along the Plum Brook just north of Columbus Avenue where a Cs-137 concentration of 72 pCi/g was measured in 2006. A station was placed about half-way between Columbus Avenue and Bogart Rd near the former Waste Water Treatment plan t outfall. Concentrations of Cs-137 between 20 and 30 pCi/g were measured in this vicinity. A station was placed on the Plum Brook Country Club (PBCC) and one was placed along the stream just north of the US Rt. 6 overpass. The dosimeter stations were placed in locations selected to represent exposure scenario settings. The stations placed between Columbus Ave. and Bogart Rd. represent "worst case" settings for the Suburban Gardner and Brooksid e Resident scenarios. The st ation placed in the PBCC was located adjacent to a cart path near the PBCC Ponds. This is in an area where contaminated sediment excavated from the PBCC Ponds was used as fill. It was selected to represent the PBCC Worker exposure scenario setting. The station placed in the Plum Brook Estuary just north of the US Rt. 6 overpass was placed in the wetlands next to the stream. It was selected to represent the setting for the Recreationist exposure scenario. Seven locations were selected for background measurements. All are within the 6400 acre Plum Brook Facility, but outside the PBRF. Background locations were selected at stream locations not impacted by PBRF operations. Four TLD stations were placed along the Plum Brook upstream (south) of the Pentolite Ditch. They covered the stream from its point of entry to the Plum Brook Facility to a point about 1/2 mi. south of Pentolite Ditch. Locations at three other streams that traverse the facility were also selected. These incl ude Pipe Creek, a large perennial stream and two smaller streams within the Facility: Ransome Creek and Lindsley Ditch. The background locations were selected to represent the range of hydrologic and geologic settings traversed by the Plum Brook. Dosimeter handling and placement were controlled under a Survey Request prepared in accordance with PBRF procedures. 4 The dosimeter locations and placement instructions are summarized in Table 2. The dosimeters were pl aced on July 15-17 and retrieved on October 30, 2008. Photos of each location were taken at the time of placement. Radiological survey measurements (dose rates) were also taken at each location at placement and retrieval. Attachment A, Dosimeter Placement Report, documents the date and time of placement and retrieval and the setting and conditions for each location. Control TLDs from the same batch supplied by the vendor were placed in a shie lded enclosure during the exposure period. 4 Survey Request, SR-117, Plum Brook and Environs (Plum Brook Environmental Dosimeter Study), issued July 15, 2008.

TBD-08-006, Appendix C Page 11 of 55, Rev 0 6.0 Analysis of Results Results of measurements with TLD and microR meters are presented. Doses measured with TLDs are first converted to dose rates using a simplified method without background subtraction for comparison with microR meter measurements at the dosimetry sta tion locations. Following this, the TLD results are evaluated to obtain the net dose from terrestrial gamma radiation sources for comparison with cal culated outdoor dose rates obtain ed for the exposure scenarios from the RESRAD dose assessment results.

Table 3 shows the reported dose results for the individual TLD badges - from the dosimetry vendor report in Attachment B. The table show s the reported doses from individual badge elements and the calculated badge element averages, which are the reported doses from each dosimeter. The uncertainty of each TLD badge dose is shown in the table as the standard deviation of the badge element doses. 5 5 The Dosimetry vendor states that the uncertainty is reported as 0.2643 x the average of the badge element doses in mR; equivalent to the two-sigma uncertainty [Mirion 2008].

A comparison is made of measured TLD doses with dose rates measured at each location at placement and removal. The TLD doses reported in mR in Table 3 are converted to µR/h by dividing by the number of hours that th e badges were exposed in the field. 6 Table 4 shows the

The individual field measurem ents are reported in Table 9 in Attachment A. This comparison assumes that th e TLD exposure prior to and after placement is small in comparison to the exposure from the field placement period. The total life cycle for the TLD batch was 148 days and the average field exposure was 106 days. Dose rates obtained from TLD measurements and from the microR meter measurements are in good agreement. A correlation coefficient (R

The TLD results are evaluated further for comparison with the calculated scenario doses. A statistical analysis of the TLD measurement data was performed. It is reported in Attachment D. From this analysis it is concl uded that the control badges provide a better estimate of the TLD

7 The survey instrument used was a Ludlum Model 19 microR meter. Three microR meter measurements were taken at each badge position (1 meter and 2/3 meters from the ground surface) at each TLD station at the time of placement and again at the time of badge removal.

TBD-08-006, Appendix C Page 14 of 55, Rev 0 measurement uncertainty for present purposes th an does the vendor's reported "generic" badge dose uncertainty. The Appendix D report evaluates the TLD background mean dose and associated uncertainty. These results are used in the evaluation of TLD measurements described below. A simple model is used for estimating the net dose measured with environmental TLDs. In this model, the net TLD dose is assumed to be due to gamma radiation from contaminated sediments.

The life cycle of the TLD badges comprises three main periods: pre-placement, field exposure period and post-placement. Pre-placement is the period from badge annealing at the vendor's facility to placement in the field. Post placement is the period from badge retrieval to badge processing (reading). The badges are designed to measure x, gamma, neutron and high-energy beta radiation. The badge packaging filters-out low energy electrons and beta rays. The principal measured exposure components are gamma rays of terrestrial origin a nd secondary radiation from cosmic radiation interactions in the atmosphere [Burke 1972]. Natural airborne radioactivity (of cosmic ray orig in and radon) also contributes.

The badges are divided into three groups. They are: 10 badges placed in locations in areas impacted by contaminated sediments (identified as MSA badges), 14 badges placed in areas not impacted by contaminated sediments to measure "background" (identified as BKG badges) and 7 control badges. The control badges were placed in a lead-shielded enclosure during the field-exposure period. The minimum thickness was 2 in. This is sufficient to shield-out gamma

radiation of terrestrial origin.

During the field exposure period the dose measured by MSA badges includes contributions from: background from terrestrial sources, cosmic rays, naturally occurring airbor ne radioactivity and contaminated sediment. The BKG badges receive dose contributions from terrestrial sources, cosmic rays and naturally occurring airborne radioactivity. The control badges are exposed to cosmic rays and possibly radon and trace concentrations of radioactive contamination in the lead during the field exposure period.

The model used to estimate the net dose to an individual MSA TLD badge received from contaminated sediments is expressed as:

BTNEEE, where: (Equation 1) E N = Net exposure from contaminated sediment, E T = Total TLD badge dose, B E = Average of the background badge doses. This model assumes the following:

All the badges receive the same dose prior to and after the field placement period

TBD-08-006, Appendix C Page 15 of 55, Rev 0 T he dose contributions to MSA and BKG badges from cosmic rays, terrestrial and naturally occurring airborne radioactivity are approximately equal. Uncertainties in calculated quantities are estimated by propagation of errors. Formulae for error propagation are given below. The calculated uncertainties are the estimated "standard error" in the calculated result:

a = constant or term with negligible uncertainty [EPA 1980].

The background dose term, B E is determined. First it is noted as shown in Table 3 that the measured background doses at several background locations are significantly higher than the average observed backgrounds. It is determined from observation that the Plum Brook crosses exposed shale outcrops in the central and southern portions of the Facility. These are members of the uranium-bearing Ohio Shale formation [Harrel 1991]. Shale is observed on the ground surface at background locations BKG-3, 4, 5 and 6. 8 Dose rate measurements performed at the time of TLD placement (and removal) showed higher than expected dose rates at locations BKG-4, 5 and 6. To reduce the influence of the exposed shale, BKG-4, 5 and 6 are removed from the

data set for calculation of the average background dose. From the analysis in Attachment D, it is concluded that there is no significant difference in the doses measured by TLD badges placed at one meter and 2/3 meter from the ground. Thus, the mean background dose, B E , is obtained as the average of the eight BKG badges from the b ackground locations not influenced by the shale outcrop. As shown in Appendix D, the mean b ackground dose is calculated to be 24.63 +/- 0.86

8 The presence of uranium-bearing shale in the vicinity of the Plum Brook is also a confounding factor for gamma dose and dose rate measurements at the study area locations in the steam meander sections. While visible outcrops were not observed by the study team between the Pentolite Ditch and the PBCC, it is known that the Ohio Shale is present such that the stream bed encounters the shale in multiple locations, including the dosimetry study area.

TBD-08-006, Appendix C Page 16 of 55, Rev 0 mR. The net exposure (dose) at the measurem ent study area locations is then obtained by subtracting the mean background dose from the reported TLD badge total doses The results are shown in Table 5. Since the background badges and the MSA badges are from the same batch sent by the vendor, they received the same exposure during pre-and post-placement time intervals in the batch life cycle. These dose contributions are removed from the MSA badge doses through the background subtraction. Thus, the net badge dose is a measure of the contribution (if any) from contaminated sediments.

As described in Attachment D, two-sided 95% confidence intervals are calculated for the estimated (mean) net badge doses as follows:

t (1 - .n) = the "t" statistic, 1 - = the specified confiden ce level (here set at 95%, = 0.05),

S = the uncertainty or error in the net dose and

n = the "degrees of freedom" of the measurements used to obtain the net TLD dose. 9 The comparison is shown in Table 6. It shows that the measured doses are all lower than the doses calculated with RESRAD. The mean doses calculated with RESRAD exceed the upper bound of the measured TLD doses for all except the Brookside Resident scenar io site. This test 9 Details of confidence interval calculations are provided in Attachment D.

1. Net µR meter dose rates are obtained by subtracting the average background dose rate (7.96 +/- 0.29) from the average gross

µR meter dose rate at each MSA badge location reported in Table 4. The average gross µR meter dose rates at each MSA badge location are the average of 6 individual measurements and the average background dose rate is estimated as the average of 48 background measurements (six measurements were taken at each background and MSA badge location - three at the time of TLD placement and three at TLD removal.

2. The uncertainty of each net

µR meter Dose rate is estimated to be 0.94 (0.944) µR with over 48 degrees of freedom. The value of the student's t statistic used in the construction of the confidence interval bounds is 2.0.

3. The results in this column are from Table 1.

7.0 Conclusions Dose rates were measured with TLDs and with microR meters at locations along the Plum Brook selected to be representative of exposure scen arios used in the dose assessment with RESRAD. These measurement results are compared to di rect exposure pathway outdoor doses calculated using RESRAD results from f our exposure scenarios. The principal conclusions are: The 95% upper confidence limit of the measur ed TLD doses are less than the direct pathway doses calculated with RESRAD for all measurement locations except at the location selected to represent the Brookside Resident scenario. In this case the doses are equivalent. Identical results are obtained from measurements using an independent method - dose rates measured with microR meters. This comparison shows that measured dose rates are less than calculated dose rates at all locations except the Brookside Resident scenario location where measured and calcu lated dose rates are equivalent. These results confirm that the dose assessment results are conservative.

TBD-08-006, Appendix C Page 21 of 55, Rev 0 This attachment describes the locations of dosimeter stations and documents the details of their placement for the environmental dosimeter study of the Plum Brook. Dosimeters were placed at five locations designated as measurement st udy area (MSA) locations and seven locations designated as background reference locations (BKG). Each dosimeter includes two TLDs. One is placed at one meter from the surface to correspond to the "dose receptor point" for whole body dose from external exposure to an adult. A second dosimeter is placed at 2/3 meters from the surface to correspond to the dose receptor point for a juvenile (11 to 12 year old). A summary description and photo of each location is provided followed by an index of the individual TLD badge numbers and a table showing microR meter measurements at placement and removal. Background Dosimeter Location, BKG-1. The dosimeter station is located on Ransome Creek at the Pentolite Road crossi ng about 50 yards west of the warehouse Buildings 9201. The TLD station was placed along the east side of the creek bank north of the road. Note. This creek is identified as Taylor Ditch on some maps. The station was set up and the dosimeters placed on 7/15/08 at 1340. The dosimeters we re retrieved on 10/30/08 at 1110. Dose rates measured at time of placement at the TLD badge positions ranged from 8 R/h (at one meter from the ground surface) to 9 R/h (at 2/3 meter from the ground surface).

This is near the intersection of Columbus and Taylor Roads, just north of the Plum Brook Facility entrance in Perkins Twp, Erie County. Th e TLD station was installed on 7/16/08 at 1545. This is a bias ed location selected to coinci de with the location (survey location OL4-2, EMA-1, sm-6 in SR-45) where a Cs-137 concentration of 72 pCi/g was measured in 2006. This location is where the highest concentration of Cs-137 in sediment was measured outside the Plum Brook Facility. At time of placement, the dose rate measured at the TLD badge one-meter position was 11 R/h. It was 12 R/h at 2/3 meter from the ground surface. The dosimeters were retrieved on 10/30/08 at 1030. Figure 12 shows the TLD station at the time of placement. Figure 12, Dosimeter Station MSA-2 as Installed

Review of Environmental Dosimetry Study Draft Report - TBD-08-006 Appendix C - Revised Review Report SummaryI have reviewed the subject draft report. Per your request, my review focused on thefollowing items:*Evaluate the application of statistical concepts to the treatment of availablemeasurement data.*Are these concepts appropriate for the interpretation of the available dosemeasurements and making of comparisons with calculated doses?*Are the calculated statistics appropriate and accurate?*Are the application and treatment of measurement error and tests of equivalencebetween measured and calculated doses adequately explained? The basic statistical concepts appear to be appropriate for the interpretation of the dosemeasurement data and comparison with calculated direct pathway doses (RESRAD). The application of those concepts, however, relies too heavily on the estimate of total uncertaintyreported by the manufacturer of the thermoluminescence dosimeters (TLDs) in my opinion. This manufacturer reports the total dose uncertainty as being 26.4 percent ( Personal communication

R. Cords to B. Mann, 2008). It is this value that is used throughout the report as the basis for error propagation without an adequate explanation as to what "26.4 percent" really means. The data collected from the various TLDs employed during this investigation provide agreat deal of empirical information regarding the uncertainty of the dose measurements. This information has not been fully exploited in the subject report. Admittedly, the extraction of that Page 2 Mr. Bruce Mann

March 9, 2009empirical information is not as straight forward as it could be had the study design been modifiedslightly. This modification would be to place a second TLD at each height and each location ofthe field monitoring sites. Such replication would have enabled the direct assessment of the basic measurement "error," i.e. the differences between two TLDs measuring the same thing.Sans replication, an empirical estimate of measurement variation must be teased out ofthe available data. Fortunately, the subject report contains a clear description of the study design and TLD placement so that this is possible. The following sections detail the empirical assessment of measurement uncertainty. Uncertainty of a Single Badge Dose ReadingEach TLD badge contains three "elements." Each element records a dose accumulatedover the duration of exposure. These three accumulated doses are averaged to produce a badgeaverage accumulated dose. A first step in assessing the measurement system uncertainty is to determine whether or not the variation among element doses is important as compared to the variation among badge average doses. Fortunately, this study provides for such an assessment

with the badges in the"Control Group." The seven badges in the Control Group were placed in a lead-shielded enclosure duringthe field-exposure period. The thickness of the enclosure was sufficient to shield-out gamma radiation of terrestrial origin. All seven badges were then measuring the same radiation for all practical purposes. A scatter diagram of the resulting dose measurements for each dosimeter element is presented in Figure 1 below.One might speculate in regard to the pattern of the scatter diagram and the sequence ofdosimeter identification numbers. It would have been better from an experimental design perspective to have chosen the dosimeters for each exposure condition at random from the total lot of available dosimeters. For purposes of this investigation, it will be assumed that the dosimeters were numbered at random within the sequence of production.Note from Figure 1 that there appears to be greater variation among the dosimeter meandoses than that exhibited among the elements within each dosimeter. These components of the total variation in dose measurements can be separately quantified by performing an analysis of variance (ANOVA) as illustrated below. Because one can not identify a specific element dose measurement without identifying a specific dosimeter, the elements are considered to be "nested" within the dosimeter when performing the ANOVA. Page 3 Mr. Bruce Mann

March 9, 2009The ANOVA is simply the division of the total sum of squared deviations of eachelement dose measurement from the total mean dose into its component parts. One part is the sum of squared deviations of each dosimeter badge mean dose about the total mean dose. This will be referred to as the "among badges" fraction. The other part is the sum of the squared deviations of each element dose from the mean dose for its specific dosimeter badge. This will

be referred to as the "within badges" fraction. The results of these calculations are presented in

the following Table 1.The "degrees of freedom" become the divisor of the sum of squares to estimate the"mean square" or variance associated with that source of variation. Because there are 7 dosimeters in the control group there are 6, (7-1), degrees of freedom available. Because there are 3 elements within each of the 7 dosimeters there are 14, [7(3-1)], degrees of freedom available for the within dosimeter variation. The total degrees of freedom is just the total number of dose measurements minus one, (73-1).

The F-ratio is simply the ratio of the among mean square to the within mean square and is the well known F statistic. The P-value is the probability that one would get a value of the F-ratio strictly by chance if the mean squares were in fact the same. Thus it represents the probability of being wrong in concluding that the mean squares are different when in fact they are the same. Clearly, there is significantly more variation among badge means than there is among element measurements within a badge.The expected mean squares symbolize the make up of the variation from each source. The represents the variance among elements within a badge. The represents the S E 2 S B 2variance associated with the mean badge reading from its true value within the control group. That which is desired is the variance associated with a single badge reading, i.e. the mean of the element readings for a single badge. This can be symbolized as follows: .S S S C E B 2 2 2 3This is just the expected mean square for Among Badges divided by the number of elements

within a badge. Defining the variation of the mean of the three element readings within a badge as S S EM E 2 2 3we can re-express the variance of a single badge mean reading as . SSSCEMB222This relationship indicates that the variation (uncertainty) of a single badge dose measurement is composed of the variation associated with the mean element dose within a badge and the variation of an individual badge measurement from the mean of all badges having the same Page 5 Mr. Bruce Mann

March 9, 2009exposure. Note also that the above relationship is in the form of a relationship for right triangles theorized by Pythagorus.Equating the expected mean squares and the estimated mean squares we may obtainestimates for , and subsequently . We may then geometrically represent the S B 2 S E 2 S EM 2 relationship as follows.Thus the estimate of the standard deviation of a single badge dose measurement is 1.136 mR based upon the results from the seven badges in the Control Group. This estimate will be carried forward as the standard deviation of a single badge measurement and become the basic yard stick

against which all further analyses are judged. It is standard practice, not necessarily good statistics, to take +/-3 standard deviations assome indication of an expression of uncertainty. Doing so, three standard deviations is 3.408 mR and dividing this value by the observed control mean of 13.190 we obtain a ratio of 0.2584 not too different from the manufacturer's 0.2643. One is left to speculate that the manufacturer'sclaim of 26.43 percent uncertainty may have some degree of confidence built in and is not an estimate of the single badge variance. BackgroundSeven locations believed not to be impacted by PBRF operations were chosen asrepresentative of "background" radiological conditions at the site. Two dosimeters were placedat each location. One was placed at a height of 0.67 meter (m) above ground surface to correspond to the modeled dose receptor point for a 10 to 12 year old child. The other was placed at 1m above ground surface corresponding to the modeled dose receptor point for an adult. The dosimeter element results for these background measurements are presented in the

following Figure 3.Control GroupVariation of a Single Badge Reading Amon g Bad ges, S B=1.071 S EM=0.378ElementsMean of 3Si n g l e Badg e R e a d i n g , S C=1.1 3 6 Figure 2 Page 6 Mr. Bruce Mann

March 9, 2009 Most striking in this figure is the apparent difference between the results for backgroundmeasurements from dosimeters at locations 4, 5 and 6 and the measurements made at the other

background locations. Post study investigation revealed that locations 4, 5 and 6 were influenced by an outcrop of the uranium-bearing Ohio Shale formation. The data from these locations provide information on the variation of dose measurements in the field. This is true

even though the results at these three locations represent the background dose level for site areas having exposed shale outcrop, not areas similar to the study area. Therefore, the data from these locations are retained for estimating measurement variation, but eliminated for estimating the

average background dose.Background Badge Readings by Location1.0 mete r0.67 meterHeight01234567 8Background Location No. 20 30 40 50Element Reading, mR Figure 3 Page 7 Mr. Bruce Mann

March 9, 2009Another observation from Figure 3 is that the differences between measurements atdifferent heights appear to be not much different than those among elements within a dosimeter. This suggests that there is no significant difference in measurements due to the placement height in the background area. This is confirmed via an ANOVA of the dosimeter averages given in Table 2 below. The variation elements within a dosimeter has minimal influence as indicated for

the Control Group and further consideration adds nothing to the evaluation. Table 2 ANOVA - Background GroupSource of VariationSum of Squares Degrees of Freedom Mean SquareF-ratioP-value Shale520.3501520.35043.2260.001 Height0.03210.0320.0250.880 Location within

March 9, 2009Because there is no significant difference in dosimeter readings associated withplacement height, the two dosimeter readings at each location can be considered replicate measurements at that location. The variance of a background dosimeter reading can now be estimated as the pooled variance among dosimeter readings within each shale exposure group. This variance can be broken down into two components as shown in Table 3, the variation due to dosimeters at the same location (Between Badges) and the variation due to differences in location within the background area (Among Locations).This can be geometrically represented as follows.There are eight badges with exposure not influenced by the shale outcrop. The mean dose, , E B is the average badge reading of 24.625. The variance of this average is then .S SBKGBKG 2 2 807403.Net Dose at Study LocationsDosimeters were placed at four locations that were thought to represent four modeled dose scenarios. An additional location, MSA-1, was chosen based upon the observation of high field measurements even though it is not generally accessible to the public. Dosimeters were placed at heights of 0.67 m and 1 m at each location. Because there is no evidence to suggest that placement height is not important in the study locations, each dosimeter reading is treated

separately. Background DosimetersVariation of a Single Badge Reading Amon g Locations, S L=3.470 S B=1.247LocationBadges a tSi ngl e Badge R e adi ng, S B K G=2.43 4 Figure 4 Page 9 Mr. Bruce Mann

Therefore, confidence intervals may

be constructed for the expected net exposures using the student's t statistic. However, the variance of a single badge reading is estimated from the Control Group with 6 degrees of freedom, but the variance of the background mean is estimated with 12 degrees of freedom. Therefore, we are faced with some question as to which value of the tabulated student's t tochoose. A reasonable approach is to use a "weighted t" following Cochran's approximation.Net ExposureVariation of a Single Badge ReadingSin gle Dosimeter Readin g , S C=1.136 S BKG=0.860BackgroundAverage S i n g l e B a d g e N e t R e a d i n g , S N=1.4 2 5 Figure 5 Page 10 Mr. Bruce Mann

I have constructed the attached table as a suggested revision to

your Table 10. Note that only the "Resident" RESRAD calculated dose is included within the 95 percent confidence intervals for the mean net dose at the selected locations within the study area. Assuming that the observed individual badge readings are representative of the dose for their respective scenario, the observed net dose is statistically significantly lower than that predicted

by RESRAD for all but the residential scenario. Thus the RESRAD predicted doses are

conservative. Dose Rate EstimationThe subject report has paralleled the discussion of dose in mR with a discussion of dose rate in rem/h derived from the TLD measurements. The total deviation of badge exposure timefor the entire study was 48 hours with the average time of 2,568 hours. This is a less than twopercent deviation and suggests that conversion of the exposure results (in mR) to results for dose

rates (in rem/h) might be accomplished simply by dividing by the average exposure time. Very truly yours, SPLITSTONE & ASSOCIATES Douglas E.

1.0 Introduction

This appendix identifies the parameters selected for the four principal exposure scenarios: Suburban Gardner, Brookside Resident, Plum Brook Country Club Maintenance Worker and Recreationist. It documents parameter values, identifies sources of information and provides justification as appropriate. The applicable exposure pathways and source term model are described for each scenario. The RESRAD parameters that apply to each scenario are then presented and discussed. The organization in th is appendix follows the structure used by RESRAD for identifying parameters: Contaminated Zone Parameters Cover and Contaminated Zone Hydrologic Data Saturated Zone Hydrologic Data Uncontaminated and Unsatura ted Zone Hydrologic Data Distribution Coefficients Dust Inhalation and External Gamma Parameters Ingestion Pathway Dietary Parameters Ingestion Pathway Non-dietary Parameters Dose conversion, food transfer and bioaccumulation factors.

TBD-08-006, Appendix D Page 4 of 18, Rev 0 2.0 Exposure Pathways and Source Term Models

The exposure pathways for each scenario are summarized in Table 1. Table 2 summarizes the source terms models. This information is contained in the main report, but is presented here as a guide for identifying the parameters used in each scenario.

(2) Modeled as cylindrical three-layer source; three meter radius. Surface layer is 6 in. thick; subsurface layers are each 12 in. thick. (3) Principal source is single-layer only for Co-

60. Localized elevated activity source is Cs-137 only (no Co-60 activity).

Table 2 Notes:

1. The plant food pathway is suppressed for the Suburban Gardner localized area elevated activity source. It is assumed to be located outside the garden.

2. Special considerations are required to implement the three-layer source models. The direct exposure pathway dose from Cs-137 is modeled separately from the fish ingestion pathway dose. The direct pathway dose can be modeled by three separate RESRAD cases; one for each layer. The doses from each layer are additive. However, for the fish ingestion pathway dose RESRAD cannot accommodate three distinct contaminated zone layers as the contaminated zone must be in direct contact with the saturated zone. The contaminated zone is treated as a single layer of thickness equal to the total thickness of the three layers.

3. The localized area source for Cs-137 is modeled similarly to the large area source as described in Note 2. The source area is set at 28.3 m 2 (3 meter radius).

TBD-08-006, Appendix D Page 8 of 18, Rev 0 3.0 Parameter Data Tables The tables which follow summarize the RESRAD parameter values selected for the exposure scenarios. The Suburban Gardner is addressed in Tables 3 through 9; Brookside Resident in Tables 10 and 11; Plum Brook Country Club Maintenance Worker in Tables 12 and 13 and Recreationist in Tables 14 thr ough 19. Distribution coefficients fo r all scenarios are presented in Table 20. Dose conversion, food transfer and bioaccumulation factors are given in Table 21. For each parameter, the RESRAD parameter name is used as the identifier. The parameter value and units are given and the source or basis for the selected value is given. Note that only the Suburban Gardner and Recreationist scenario s contain pathways th at involve hydrologic parameters. Published hydrologic parameter data for Plum Brook sediment settings that lie outside the Plum Brook facility are scarce. Some hydrologic parameter data was provided by a consulting hydrogeologist (Haag Environmental). Of necessity, primary sources are the PBRF FSS Plan (Attachment B) [NASA 2007] and the US Army Corps of Engineers PBRF Hydrogeological Report [USACE 2004]. In the absence of published data or professional observations for local conditions , general hydrology references or RESRAD default values are used [ANL 2001]. For behavioral and food chain parameters, RESRAD default parameter values or values published in US N RC guidance documents are used.

1.0 Introduction Information on the releases of radioactivity to the Plum Brook from the PBRF has been provided by NASA to the public on several occasions. Qu estions have been ra ised about doses and potential risks to children. Th e dose conversion factors and behavioral parameters for RESRAD models and exposure scenarios are based on adults. What are the effects on the calculated doses if age-dependent values of critical parameters are used to calculate the doses? As a result, NASA has requested that a technical evaluation be performed to a ddress this issue. This report describes the assessment of age-dependent doses for selected exposure scenarios and compares them to adult doses calculated in the 2008 dose assessment [NASA 2008]. 2.0 Background

Environmental radiation dose calculation models such as RESRAD were developed using dose factors published by the International Commission on Radiological Protection (ICRP) and the US EPA. The dose factors were developed for assessment of doses to adults. In the absence of age-specific dose and risk factors, the assessment of dose and risk to members of the public was limited to adults. The EPA acknowledged this situation in a 1 994 Federal Register announcement. 1 The US NRC concurred with this policy on assessment of doses to future site occupants from residual contamination at decommissioned nuclear facilities. 2 However, beginning in 1989 the International Commission on Radiological Protection (ICRP) issued age-dependent dose factors for assessment of doses to the public from intake of radionuclides, culmina ting in the issuance of ICRP Report No. 72 in 1996. [ICRP 1996]. Subseque ntly, the EPA has issued age-dependent cancer risk coefficients for environmenta l exposure to radionuclides [USEPA 1999].

The developers of RESRAD have incorporated IC RP-72 age-dependent dose factors in version 6.4 of the code released in December 2007 [USD OE 2008]. It is now possible, using RESRAD to calculate doses to individuals other than adults from exposure to Plum Brook sediments. The RESRAD age-dependent dose conversion factors for Cs-137 (from ICRP-72) are shown in Table

1. The table compares them to the adult dose fact ors in the RESRAD default dose factor library -

1 "The actual dose to a particular individual from a given intake (of radioactive material) is dependent on age and sex as well as other characteristics. -implementing limits for the general public expressed as age and sex dependent would be difficult. More importantly, the variability in dose due to these factors is comparable in magnitude to the uncertainty in our estimates of the risks--EPA believes that for purposes of providing radiation protection, the assumptions exemplified by Reference Man adequately characterize the general public and a detailed consideration of age and sex is not generally necessary [USEPA 1994]. 2 "Since age-based dose conversion factors are not being used, the same dose conversion factors are applied to all individuals. Only in rare occasions will a non-adult individual receive a higher dose than an adult in a similar exposure scenario. One example is the milk pathway; children generally drink more milk than adults. If milk was the only pathway that would expose the individual to a dose, then the child would have a slightly higher dose than the adult. But in most situations, especially ones involving multiple pathways, the total intake of the adult is greater than that of a child" [USNRC 2003].

TBD-08-006, Appendix E Page 4 of 16, Rev. 0 from Federal Guidance Report No. 11(FGR-11) [U SEPA 1988]. The latter were used in the recent dose assessment for exposure to Plum Brook sediments [NASA 2008]. Note that the adult dose factor for inhalation has been reduced by over a factor of two from FGR-11, whereas the ingestion dose factor is change d only slightly. The new dose fact or library in RESRAD does not include age dependent dose conversion f actors for the direct exposure pathway

3 The new ICRP-72 dose conversion factors are limited to internal exposures. As of the present, no effort has been funded to develop age-dependent dose conversion factors for exposure to radiation sources external to the body [Ecker. 2008].

4.0 Summary of Doses to Adults The starting point for the present evaluation of doses to children is a review of the estimated doses to adults from Plum Brook sediments. In the recent dose assessment conducted by NASA, doses to adult members of the public were cal culated for four exposure scenarios [NASA 2008]. The exposure scenarios are:

Suburban Gardner. This scenario represents exposure conditions for the portion of the stream nearest the PBRF where a resident grows vegetables in a small garden on soil that is mixed with contaminated sediments. Radiation exposure is received primarily from direct exposure while working in the garden 123 hours a year and from consumption of vegetables grown in

the garden. Brook-side Resident. A residence is assumed to be constructed on land contaminated with sediments deposited in the vicinity of the stream during a larg e flood event prior to construction of the home. Exposure to the resident is received primarily from direct exposure while inside the house (1096 hours per year) and while occupying contaminated outdoor areas while doing yard wo rk (80 hours per year). Country Club Maintenance Worker. The dose recept or for this scenario is a worker at the Plum Brook Country Club, located on the Plum Brook about 2 1/2 miles downstream (north) of the PBRF. The worker is assumed to spend about 15 hours a week, during a 30 week golf season, traveling on and maintaining landscaping adjacent to a golf cart path constructed on contaminated sediment used as fill. Recreationist. A fisherman occupies the stream and stream bank while fishing in the stream mouth-flood plain located between US Rt. 6 and Sandusky Bay. The fisherman spends about 10 hours a week for 10 weeks a year at the stream and consumes game fish caught there [NASA 2008].

Table 2 presents the dose from Cs-137 for each of the scenarios. The numbers in parentheses are the percentages of the total dose contributed by each pathway. Probabilistic results are also shown to identify the uncertainty in the calculated doses (mean of the peak dose +/- one standard deviation). It is seen that the direct exposure pathway is the larg est contributor in all except the Recreationist Scenario. The dose from food consumption is significant in the Suburban Gardner and Recreationist Scenarios. The contributions from inhalation of suspended sediment and direct ingestion of sediment are quite small for all four scenarios. They are shown in Table 3 to provide

TBD-08-006, Appendix E Page 7 of 16, Rev. 0 a baseline for discussion of pathway contribu tions to age-dependent doses. The RESRAD case run reports for the four scenarios are included in Attachment A.

First, doses for age groups are calculated for scenarios selected from the four described above. Then an exposure scenario is developed to provide a bounding estimate for the dose to a child.

The principal factors which influence age-dependent doses calculated with RESRAD are: radionuclide-specific dose conversion f actors for ingestion and inhalation behavioral and metabolic parameters.

As discussed earlier, the new ICRP age-de pendent dose conversion factors have been incorporated into RESRAD data libraries. In ad dition, user-defined age-dependent behavioral and metabolic parameters are required. For the exposure pathways in this analysis they are rates

TBD-08-006, Appendix E Page 8 of 16, Rev. 0 for: inhalation, direct ingestion of sediment-dust, vegetable consumption and fish consumption. Values for these parameters were obtained for the six ICRP-72 age categorie s: adult, infant, 1-yr old, 5-year old, 10-year old and 15-year old

4. They are tabulated in Tables 4 and 5. As seen in the table notes, age categories in the source refe rences do not always alig n with those of ICRP-72. Explanation of assignment s is provided in the notes.

The Suburban Gardner and Recreati onist scenarios are selected fo r calculation of age-dependent doses. These scenarios are selected because they have food consumption pathways, where the effect of age-dependent parameters can be readily observed. Also, a bounding scenario, called the Playground scenario is constructed. The Playground scenario is an extension of the Brookside Resident scenario - modified so the dose receptor is a child who plays in or near the stream and on a play area constructed on land that was impacted by a flood event. The outdoor occupancy time is the most significant factor and it is based on the Country Club Maintenance Worker scenario of the recent study [NASA 2008]. The Maintenance Worker has the greatest outdoor occupancy time of the four orig inal scenarios; 450 hours per year. Since there are no age-dependent dose conversion factors available for use in RESRAD for the direct exposure pathway, the effect of age-de pendence on this pathway dose is treated by an adjustment factor. To a first approximation, ag e-dependent effective dose equivalents from the direct exposure pathway can be obtained by adjusting the adult dose by a multiplier. Results from calculations publis hed in the Journal, Radiation Protection Dosimetry are used to provide empirical adjustment factors [Petous 1991]. The cal culated doses for age categories: infant, 1-yr and 5-yr are adjusted by a factor of 1.3 and th e doses for age categories 10-yr and 15-yr are adjusted by a factor of 1.1. This adjustment is only applied to RESRAD doses for direct outdoor exposure to contaminated sediments. It is not applied to direct exposure from indoor occupancy

as the indoor exposure model does not lend itself to a simple correction factor based on the source-to-receptor distance.

4 The principal sources for age-dependent behavioral and metabolic parameter values are the RESRAD Data Collection Handbook [ANL 1993] and the EPA Exposure Factor Handbook [EPA 1994].

The direct exposure pathway dose was adjusted by an empirical factor as described in the previous section. The age-dependent total doses (with adjustments) for each scenario are shown in Table 8. The Table 8 data is plot ted in Figure 1. It is seen that the dose to children exceeds the dose to an adult only in the Playground scenario, where the dose is dominated by the external exposure pathway. 5 Table 8, Deterministic Age-dependent Doses with Direct Exposure Pathway Adjustment Dose from Cs-137 (mrem/y per pCi/g) Age-Category Suburban Gardner Recreationist Playground Adult 3.94E-02 1.05E-01 1.03E-01 Infant 3.32E-02 4.67E-02 1.34E-01 1-yr 3.61E-02 7.15E-02 1.34E-01 5-yr 3.55E-02 6.65E-02 1.34E-01 10-yr 3.13E-02 6.80E-02 1.13E-01 15-yr 3.23E-02 7.66E-02 1.13E-01 Figure 1, Comparison of Age Category Doses 0.00E+002.00E-024.00E-02 6.00E-02 8.00E-02 1.00E-01 1.20E-011.40E-011.60E-01Adu lt In fant 1-yr 5-yr 10 y r 15 y rAge CategoryDose (mrem/y)Suburban GardnerRecreationistPlayground

5 Infant doses are lower than for other age groups in the Suburban Gardner and Recreationist scenarios because their diet does not include vegetables grown in the garden or fish caught in the stream.

The dose fraction from food ingestion is greatest for the adult in both scenarios. The dose contributions from inhalation and direct ingestion of soil are negligible for all age categories.

Age-dependent doses were calculated for three exposure scenarios selected to il lustrate the effects of age-dependent dose model parameters and to obtain a reasonable upper-bound estimate of the dose to a child. The highest calculated dose was 0.13 mrem/y per pCi/g of Cs-137 for a small child who is in direct contact with contaminated sediments for 450 hours a year. This could be ach ieved by a child who plays outdoors an average

of 15 hours a week for 30 weeks a year in an area containing contaminated sediments. This is considered to be a bounding scenario as there are limited opportunitie s for prolonged contact with Plum Brook sediments. The highest calculated dose to a child is less than the highest dose to an adult, 0.17 mrem/y per pCi/g calculated in the dose assessment reported by NASA in June, 2008 [NASA 2008].

Overall, the doses from exposure to individuals from contaminated sedi ments are not strongly age-dependent. It is concluded that the use of an adult as the average member of the exposed critical group is reasonable for assessment of the dose and risk impact. There is no age group which receives a higher dose than adults.

1.0 Introduction This appendix describes the se nsitivity analysis for the Plum Brook sediment dose assessment. The dose assessment calculations using RESRAD a nd the four principal exposure scenarios are evaluated. The first objective is to identify the RESRAD model parameters that have the most significant effect on the calculated doses. In this context "sensitivity" is defined as "the degree to which model outputs are affected by changes in input values". 1 The second objective is to obtain uncertainty estimates for calculated doses. This is accomplished using RESRAD probabilistic analysis capabilities. The most sensitive model parameters are sampled and correlation measures

calculated. Corresponding output dose distributions are obt ained. These include dose uncertainties and parameter sensitivity rankings. Also discussed are overall uncertainty in calculated doses and source term model assumptions.

2.0 Background and Approach

The approach to be followed is to first perform a "screening analysis" to determine the most sensitive parameters. This is accomplished in two steps. The first step is to identify the most significant pathway contributors to dose among the exposure scenarios developed for the dose assessment. This is accomplished by calculating doses from unit concentration of Cs-137 and Co-60 for each scenario using the standard parameter values developed in Appendix D of this report. Then the total scenario and pathway doses for each radionuclide are calculated using the concentrations of each radionuclide. The results are evaluated to obtain a ranking of the pathways, ranked in terms of their co ntribution to total scenario dose.

The second part of the screening analysis is to screen input parameters for the most dose-significant pathways. Principal parameters for each pathway in the four scenarios are identified in Appendix D. The RESRAD sensitivity analysis capability is used to perform a comprehensive screening of the input paramete rs for two representative exposure scenarios: the Suburban Gardner and Recreationist scenarios. They represent all the pathways considered in the dose assessment: direct exposure to groun d source, ingestion of garden vegetables, ingestion of fish, inhalation of suspended dust and direct ingestion of suspended dust. Sensitivity analysis reports are generated for each parameter. Non-significant input variables or parameters are identified and eliminated from further consideration. Then, the parameters that show sensitivity effects are

identified and ranked.

After the "sensitive" parameters are identified for each exposure scenario, uncertainty analysis is performed using RESRAD probabilistic analysis capabilities. Samp ling distributions are selected for the sensitive parameters. Dose distributions, peak mean doses and standard deviations of the mean doses are calculated. Partial rank correlation coefficients are used to confirm the selection of sensitive parameters in the screening analysis. The resultant parameter sets and sampling distributions are then used for the RESRAD case runs in the complete dose assessment. 1 From EPA Draft Guidance on the Development, Evaluation and Application of Regulatory Environmental Models [USEPA 2003].

TBD-08-006, Appendix F Page 6 of 303, Rev 0 4.0 Analysis 4.1 Pathway Ranking Doses are calculated for each scenario using the RESRAD deterministic mode with the basic parameter values established in Appendix D. Unit doses (mrem/y per pCi/g) are converted to total dose (mrem/y) by multiply ing by concentration of each of the two radionuclides of concern (Cs-137 and Co-60). Table 1 shows the results. The minor pathways, direct ingestion and dust inhalation have been eliminated by inspection as they are less than 0.01 % of the total dose in all scenarios. The Tabl e 1 results are then ranked by sorting on the dose field in descending order. The pathway rankings are shown in Table 2.

The pathway ranking shows that the ground pathway (direct exposure) predominates for all scenarios for both radionuclides. The highe st ranked pathway dose is direct exposure to the Brookside Resident from Cs-137. The highest ranked food pathway dose is Suburban Gardner consumption of vegetables contaminated with Cs -137, but it is less than 10% of the highest-ranked pathway dose.

Sensitive input parameters may be identified by examination of the RESRAD equations or by using the RESRAD sensitivity analysis facility.

Ground exposure pathway sensitive parameters are identified by examining the RESRAD equation for direct exposure pathway dose. Fo r a single radionuclide, it is of the form [ANL 2001]:

FCxFAxFSxFOxDCFxSD, where: (Equation 1) D = dose in mrem/y,

S = source activity concentration in pCi/g, DCF = dose conversion factor (mrem per pCi/g) in volumetrically contaminated soil, from Federal Guidance Report No. 12 [USEPA 1993],

FO = a term that includes multiplicative factors for occupancy time and shielding,

FS = a dimensionless shape factor (adjusts for non-circular source shapes), TBD-08-006, Appendix F Page 8 of 303, Rev 0 FA = a term that includes multiplicative factors for the source area, thickness and cover thickness and

FC = a depth-and-cover factor that includes terms for time-dependence of source and cover thickness due to erosion and weathering. Note this term is not a factor in the present scenarios, where the maximum dose is obtained at time, t = 0 years.

Note that the DCF and source concentration input parameters are implemented in

RESARAD as fixed-constants for each ra dionuclide. The RESRAD code does not contain provisions for applying sensitivity or uncertainty analysis to these parameters. With this in mind, it is seen from Equation 1 that key input variable parameters include occupancy time (occupancy factor), source area and source thickness. These will be evaluated using the RESRAD sensitivity analysis facility.

Examination of the RESRAD equations does not readily lend itself for screening parameters in dose pathways involving with wate r transfer processes. This is due to the multiple complex transfer equations. No further attempt is made here to use the RESRAD model equations for parameter screening.

The RESRAD sensitivity analysis tools are used to confirm the results for the direct

exposure pathway screening obtained above and to screen the remaining parameters. The sensitivity analysis facility calculates the effect on the total dose from variations in individual parameters, independently, one-at-a-time. The selected parameter value is varied by multiplying and dividing the base parameter value by a user selected factor (typically 1.5, 2, or 3) and the resultant doses are calculated. The RESRAD sensitivity analysis results are available only as graphics showing the dose vs. time for the base case, lower bound and upper bound values for each parameter. The RESRAD graphics reports for the screening analysis are provided in Attachment B.

The list of potentially sensitive parameters is greatly reduced through this process. The results of this screening process are shown in Table 3. The parameters shown were selected by inspection of all the RESRAD sens itivity analysis reports and those showing "significant" sensitivity were selected for further evaluation. Figure 1 is an example of a sensitivity analysis report showing a sensitive parameter, the out door time fraction for the Recreationist Scenario. Figure 2 is a report for a non-sensitive parameter, the saturated zone density for the same scenario. The parameter screening through RESRAD sensitivity analysis is based primarily on case runs using Cs-137. It is found that for the scenarios and their key pathway parameters examined, the differences between Cs-137 a nd Co-60 sensitivity ar e slight -not enough to significantly change the rankings. To confirm this, a few test cases were run for Co-60 parameter sensitivity analysis.

TBD-08-006, Appendix F Page 10 of 303, Rev 0 The parameters identified as showing significant sensitivity are shown in Table 3. They are ranked according to a "sensitivity index" The sensitivity index is calculated for each parameter using a definition adapted from Till and Meyer [Till 1983]. The sensitivity index is defined as:

max min/1DDSI, where: (Equation 2)

SI = Sensitivity Index (unit-less), Dmin = Dose calculated for parameter minimum value and

Dmax = Dose calculated for parameter maximum value.

4.3 Uncertainty Analysis The main objective of the uncertainty analysis is to establish a cons istent and reasonable basis for estimation of uncertainties in the doses calculated for each scenario with RESRAD. By incorporating the parameters with the greatest sensitivity in the uncertainty analysis, the main error contributions from uncertainties in parameter values are included in the calculated doses. The parameter sets developed in Appendix D and the sampling

distributions developed in this section are used in the RESRAD case runs for assessment of doses.

The uncertainty analysis was performed by us ing the RESRAD probabilistic capability. From the screening results listed in Table 3, a set of key-sensitive parameters was established for each scenario. Even though the Brookside Resident and Country Club Maintenance Worker scenarios were not screened directly, only the direct exposure pathway is significant for these scenarios. The RESRAD direct pathway model parameters identified as sensitive for th e Suburban Gardner and Recreationist were assigned to these scenarios.

Sampling distributions to be used in the uncertainty analysis were then selected for each parameter. The following references were consulted: The RESRAD User's Manual [ANL 2001], NUREG/CR-6692 [USNRC 2000], the RE SRAD Data Collection Handbook [Yu 1983] and RESRAD sample problem defaults for the Resident Farmer. For parameters

where no recommended distributions were found in references, sampling distributions were assigned based on judgment. Criteria for judgment-based sele ction included use of distributions recommended in the references for similar parameters. 2 Tables 4 through 7 show the parameter distributions selected for each scenario.

In Tables 4 through 7, the nominal parameter values from Appendix D are listed in the

second column; the sampling distributions in the third column and the sampling distribution characteristics in the fourth column. For normal distributions, the sampling distribution is completely described by the m ean and standard deviation; for triangular, the minimum, mode and maximum; for uniform, the minimum and maximum (in some cases discrete uniform distributions with spec ified values are used); for truncated normal, the mean, standard deviation and lower and upper quantiles and for lognormal-N, the mean and standard deviation of the underlying normal distribution are specified [ANL 2001].

In column five of Tables 4 through 7, the parameters are ranked according to their

relative contribution to the dose uncertainty as measured by correlation analysis of their combined effects. The selected measure, the partial rank correlation coefficient (PRCC) is one of several correlation ranking indices or measures calculated by RESRAD. It is 2 Experience has shown that for most sensitive parameters, the sampling distribution is not usually critical as long as the range of values is within a range that is reasonable based on literature results or on actual site information. Also, the central tendency should be close to the base value used in the analysis. Exceptions to this are parameters with a very wide range of values and those that are described by highly skewed distributions. In these cases, the log-normal family of distributions tends to provide "better" results (reduced bias and variance) in probabilistic analyses.

The partial rank correlation coefficients are listed in column six. Note that the parameter sensitivity rankings in Tables 4 through 7 are only slightly different than the rankings obtained by the one-at-a-time sensitivity analysis results reported in Table 3.

4.4 Discussion Additional sensitivity analysis topics are discussed. The pr evious section focuses on the effects of parameter uncertainties in the doses calculated with RESRAD. Other important contributors to the uncertainty in calculated doses are uncertainties in:

Radionuclides of concern in environmental media and their concentrations Dose to individuals from exposure to ex ternal radiation and from intakes, i.e., dose conversion factors Environmental transport models implemen ted in codes such as RESRAD [Kocher 2005]. The effects of uncertainties in radionuclide concentrations and in dose conversion factors are not included in the parameter set avai lable for probabilistic analysis in RESRAD. These are treated as fixed constants. It is estimated that uncertainties in these parameters are associated with uncertainty fact ors of between two and 10 [Kocher 2005]. 3 Model uncertainty arises from simplifying assumptions required for practical implementation of environmental assessment codes. In codes like RESRAD, sources are modeled as simple volumes of uniform contamination concentration. The environmental transport of radionuclides in environmental media is modeled assuming compartments of uniform characteristics with constant rate transf er processes. Considering the sources of uncertainty listed above, and othe rs that are not captured in th e probabilistic analysis, it is difficult to quantify the total uncertainty in the calculated doses. It is concluded that the magnitude of the uncertainty in the calculat ed doses is underestim ated. The average of the doses for the four exposure scenarios is calculated (estimated) to be less than 1 mrem/y (0.88 +/- 0.22). Given the many conservative assumptions used in the present dose assessment, this is considered to be an upper bound estimated dose. It is a factor of 28 below the target dose criterion, 25 mrem/y. He nce, the effect of the total (but unknown) uncertainty is small relative to the dose accep tance level. Uncertainties of an order of magnitude above those estimated here would still place the upper 95% confidence limit of the calculated dose below 25 mrem/y.

The characterization report has shown that contaminated sediment deposits are not

continuous along the Plum Brook. They are desc ribed as low level concentrations of about 1 pCi/g or less scatte red throughout the impacted length of Plum Brook with infrequent discrete deposits with concentr ations as high as 72 pCi/g [NASA 2009]. It is common practice in dose assessments to model source terms as two or more volumes of uniform activity. The principal source term is typically modeled as a contaminated zone of area up to 10,000 square meters

4. The effect of small-areas of elevated activity is typically modeled by defining small ar ea contaminated zones of up to 100 m 2 , also of uniform activity concentration. These are used to calculate "area factor s" for final status 3 Uncertainty factors represent the ratio of 95 th to 50 th percentiles of credible values [Kocher 2005].

4 The RESRAD default area for the generic Resident Farmer scenario is 10,000 m 2 [ANL 1993].

TBD-08-006, Appendix F Page 15 of 303, Rev 0 survey purposes, for example. This approach is used to simulate non-uniform horizontal distribution of contaminants.

In the present study, multiple-layer sources are used to simulate non-uniform vertical distribution of contamination in sediments. Depending on the scenario, the principal contaminated zone and localized small areas of elevated activity are modeled with up to three discrete layers. Calculated Cs-137 doses obtained from single volume source term models are compared with those from multi-layer models for the Brookside Resident and Maintenance Worker scenarios. Tables 8 and 9 compare Brookside Resident contaminated zone source term models. Exam ination of column two of the tables shows that there is essentially no difference in the dose from unit concentration: 2.68 +/- 1.30 E-01 mrem/y per pCi/g for the three-layer model vs. 2.59 +/- 1.29 E-01 mrem/y per pCi/g for the single layer model. When the effect of source term activity concentrations is considered, the single layer source term yiel ds a higher dose than the three-layer source term model: 3.76 +/- 3.25 E-01 vs. 2.80 +/- 3.38 E-01 mrem/y.

Th e comparison is shown in Tables 10 and 11. Column two of the tables shows that there is a small difference in the dose from unit concentration: 8.85 +/- 5.57 E-02 mrem/y per pCi/g for the three-layer model vs. 1.02 +/- 0.54 E-01 mrem/y per pCi/g for the 30 in. thick single layer model. Wh en the effect of source term activity concentrations is considered, the three-layer source term yields a

TBD-08-006, Appendix F Page 16 of 303, Rev 0 slightly higher dose than the single layer source term model: 9.37 +/- 5.76 E-01 vs. 6.0 +/- 5.32 E-01 mrem/y. It is noted that the observed differences between doses from multi-layer and single layer source term mode ls are not statisti cally significant.

Table 12

shows dose fractions (in %) vs. layer depth for the two scenarios. These are calculated from the scenario doses (mrem/y) with the sp ecified activity concentrations for each layer included. The surface layer of both source term models contribute over 80 % of the dose on average. The first and second layers comb ined contribute about 95 % of the dose.

It requires that the knowledge of contaminant di stribution be commensurate with the level of "refinement" used to model source terms. Based on the examples discussed here it is not clear that detailed source term models improve the ac curacy of calculated doses. However, they do promote better understanding of the relative contributions from subsurface layers of contaminated sediments and from local areas of elevated concentration.

The sensitivity analysis also examines the size of the contaminated zone source term used in the Recreationist scenario. No values of this parameter are available in NRC reference scenarios, for example in NUREG/CR-5512 [U SNRC 2001] as for the other scenarios. The value for this parameter was selected considering observations from the

characterization survey packages for the Plum Brook stream mouth and the Cs-137 inventory contained in contaminated zone source terms. The observation that contaminated sediments are found in lens shap ed deposits in the Plum Brook estuary and are of dimensions on the order of 10s of meters is inferred from a review of characterization survey packages [NASA 2009]. The size of the contaminated zone is assumed to be 1500 m 2 , modeled as a cylinder of radius 22 (21.85) meters. As a check on the reasonableness of this assumption, the Cs-137 inventories for contaminated zones within sizes of this range were calculated. The results are shown in Table 13. It is noted that the entire Cs-137 inventory released to the Plum Brook was estimated to be between 5 and 7.2 mCi. [Cr ooks 2006]. Using the upper end of this range and considering that 36 years have elapsed since 1973, the total remaining inventory is estimated to be no more than 3.15 mCi. This supports the conclusion that a contaminated zone area of 1500 m 2 is a quite conservative assumption. A source term model consisting of a contaminated zone area of 1500 m 2 and an elevated area of 28 m 2 contains 55% of the total Plum Brook inventory of Cs-137 of PBRF origin.

1. The source volume is comprised of three layers: the first layer is six inches thick and the underlying layers are each 12 inches thick. The total source volume includes an elevated area source of 3 meters radius and 30 inches thickness.

2. The inventories are calculated assuming an average concentration of 1 pCi/g, 0.8 pCi/g and 0.4 pCi/g in the first, second and third layers of the contaminated zone and 18 pCi/g in the elevated area source [NASA 2009].
