TBD-08-001 Page 1 of 11 Rev. 0 1.0 Introduction Cesium-137 has been measured in sediment samples collected from the portion of the Plum Brook located between the Plum Brook Reactor Facility (PBRF) and Sandusky Bay. It is known that Cs-137 was released from the PBRF in liquid effluents and subsequently entered the Plum Brook during the period of PBRF operation (1963-1973). An assessment was recently conducted to estimate radiation doses that could be received by members of the public who live or work in the vicinity of the Plum Brook [NASA 2008]. This dose assessment utilized the RESRAD computer code and exposure scenarios developed specifically to represent conditions whereby members of the public could receive radiation exposure from Cs-137 in the sediments. Following guidance from the US Nuclear Regulatory Commission (NRC), doses were calculated for an adult identified as the "average member of the critical group" [USNRC 2003] 1. The recent dose assessment reported that the estimated dose to an adult using a conservative exposure scenario is about 0.17 mrem per year. This is under the assumption that the average concentration of Cs- 137 in sediments to which the individual is exposed is 1 pCi/g, the average value measured in Plum Brook Sediments [NASA 2008].

Information on the releases to the Plum Brook has been provided by NASA to the public on several occasions. Questions have been raised about doses and potential risks to children. The default 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 address this issue.

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 1994 Federal Register announcement.2 1 The average member of the critical group is an individual who.., is assumed to represent the most likely exposure situation based on prudently conservative exposure assumptions and parameter values within the model calculations

[USNRC 2003].

2 "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].

TBD-08-001 Page 2 of 11 Rev. 0 The US NRC concurred with this policy on assessment of doses to future site occupants from residual contamination at decommissioned nuclear facilities. 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]. Subsequently, the EPA has issued age-dependent cancer risk coefficients for environmental exposure to radionuclides [USEPA 1999].

The developers of RESRAD have incorporated ICRP-72 age-dependent dose factors 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. 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 factors in the RESRAD default dose factor library -

from Federal Guidance Report No. 1 (FGR-1 1) [USEPA 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 changed only slightly. The new dose factor library in RESRAD does not include age dependent dose conversion factors for the direct exposure pathway4 Table 1, Age-dependent Dose Conversion Factors for Cs-137 Cs-137 Dose Conversion Factors Category (mrem/pCi) Source Ingestion Inhalation Adult - base case 5.OE-05 3.19E-05 FGR-11 1 Adult 4.81E-05 1.44E-05 ICRP-72 (2)

1. FGR-11 is Federal Guidance Report No. 11 [EPA 1988].

2. ICRP-72 is ICRP Report no. 72 [ICRP 1996].

3 "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].

4The 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

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 calculated for four exposure scenarios. 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 hours0.00142 days 0.0342 hours 2.03373e-4 weeks 4.68015e-5 months 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 resident is received primarily from direct exposure while inside the house (1096 hours0.0127 days 0.304 hours 0.00181 weeks 4.17028e-4 months per year) and while occupying contaminated outdoor areas while doing yard work (80 hours9.259259e-4 days 0.0222 hours 1.322751e-4 weeks 3.044e-5 months per year).

" Country Club Maintenance Worker. The dose receptor for this scenario is a worker at the Plum Brook Country Club, located on the Plum Brook about 2 V2 miles downstream (north) of the PBRF. The worker is assumed to spend about 15 hours1.736111e-4 days 0.00417 hours 2.480159e-5 weeks 5.7075e-6 months 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.

e 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 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months 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 largest 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-08-001 Page 5 of 11 Rev. 0 a baseline for discussion of pathway contributions to age-dependent doses. The RESRAD case run reports for the four scenarios are included in Appendix 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 factors for ingestion and inhalation

" behavioral and metabolic parameters.

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

TBD-08-001 Page 6 of 11 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 categories: adult, infant, 1-yr old, 5-year old, 10-year old and 15-year old 5 . They are tabulated in Tables 4 and 5. As seen in the table notes, age categories in the source references do not always align with those of ICRP-

72. Explanation of assignments is provided in the notes.

The Suburban Gardner and Recreationist scenarios are selected for 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 original scenarios; 450 hours0.00521 days 0.125 hours 7.440476e-4 weeks 1.71225e-4 months 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-dependence on this pathway is treated by an adjustment factor. To a first approximation, age-dependent effective dose equivalents from the direct exposure pathway can be obtained by.adjusting the adult dose by a multiplier. Results from calculations published in the Journal, Radiation Protection Dosimetry are used to provide empirical adjustment factors [Petous 1991]. The calculated doses for age categories: infant,' 1-yr and 5-yr are adjusted by a factor of 1.3 and the 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.

s 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 19941.

1. Vegetable consumption consists of two categories in RESRAD: garden vegetables, fruits and grains (non-leafy vegetables) and leafy vegetables (spinach and lettuce); In contrast, age-dependent vegetable consumption data in the EPA Exposure Factors Handbook does not make this distinction.

Age-dependent total vegetable consumption values are apportioned between vegetables, fruits and grains and leafy vegetables in the same ratios as the adult base case.

These results were obtained using RESRAD Version 6.4 in the deterministic mode. The uncertainty in these results is illustrated by Table 7, which shows the age-dependent doses for each scenario obtained from RESRAD probabilistic calculations. The results are the mean of the calculated peak doses (obtained at time = 0 years) + one standard deviation. The individual RESRAD case run: output reports are included in Appendix A.

The age-dependent total doses (with adjustments) for each scenario are shown in Table 8. The Table 8 data is plotted in Figure 1. It is seen that the dose to children exceeds the dose to an adult only 6 in the Playground scenario, where the dose is dominated by the external exposure pathway.

Age Category I Suburban Gardner ---- Recreationist A. Playground I 6 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.

TBD-08-001 Page 11 of 11 Rev. 0 The pathway contributions to the age category doses are shown in Tables 9 and 10 for the Suburban Gardner and Recreationist scenarios, respectively. 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.

Three exposure scenarios were selected to illustrate 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 hours0.00521 days 0.125 hours 7.440476e-4 weeks 1.71225e-4 months a year. This could be achieved by a child who plays outdoors an average of 15 hours1.736111e-4 days 0.00417 hours 2.480159e-5 weeks 5.7075e-6 months 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, 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 sediments 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.
