SUMMARY
This Annual Radiological Environmental Operating Report (AREOR) contains descriptions and results of the 2010 Radiological Environmental Monitoring Program (REMP) for the Indian Point site. The Indian Point site consists of Units 1, 2 and 3. Units 1, 2 and 3 are owned and operated by Entergy Nuclear Operations, Inc. Unit 1 was retired as a generating facility in 1974 and, as such, its reactor is no longer operated.
The REMP is used to measure the direct radiation and the airborne and waterborne pathway activity in the vicinity of the Indian Point site. Direct radiation pathways include radiation from buildings and plant structures, airborne material that might be released from the plant, cosmic radiation, fallout, and the naturally occurring radioactive materials in soil, air and water. Analysis of thermoluminescent dosimeters (TLDs), used to measure direct radiation, indicated that there were no increased radiation levels attributable to plant operations.
The airborne pathway includes measurements of air, precipitation, drinking water, and broad leaf vegetation samples. The airborne pathway measurements indicated that there was no adverse radiological impact to the surrounding environment attributed to Indian Point Station operations.
The waterborne pathway consists of Hudson River water, fish and invertebrates, aquatic vegetation, bottom sediment, and shoreline sediment. Measurements of the media comprising the waterborne pathway indicated that there was no adverse radiological impact to the surrounding environment attributed to Indian Point Station operations.
This report contains a description of the REMP and the conduct of that program as required by the IPEC Offsite Dose Calculation Manual, herein referred to as ODCM. This 2010 AREOR also contains summaries and discussions of the results of the 2010 program, trend analyses, and potential impact on the environment, land use census, and inter-laboratory comparisons.
During 2010, a total of 1166 samples were obtained out of a planned load of 1178 samples. Table B-1 presents a summary of the collected sampling results.
An investigation of groundwater contamination with tritium and other radionuclides has been ongoing since 2005 and continued throughout 2010. This investigation of potential onsite sources of contamination is not the focus of this Annual Radiological Environmental Operating Report; however, in 2006, Entergy agreed to several changes in the REMP to assure that all pathways were being evaluated. Specifically, two new groundwater wells (non-drinking water) were 1-1
designated as "boundary wells" and were sampled as groundwater samples for tritium and strontium-90 analyses and also gamma spectroscopy analysis. These wells (MW-40 and MW-51) were designated as REMP sample stations 104 and 105. In 2010, an offsite well to replace these two wells was established as sample station 106 at the Lafarge plant south of, and adjacent to, Indian Point. Once it was established, further sampling for REMP purposes at MW-40 and MW-51 was suspended. For 2010, only the sampling at the Lafarge plant was conducted - in accordance with the current applicable ODCM revision.
A 2006 change was made to the existing fish and invertebrate samples and shoreline sediment samples. The locations and frequency remained the same; however, strontium-90 was added, as also now is Ni-63, to the required analyses.
These additions were observed for the sampling and analyses conducted in 2010.
These changes were captured in the ODCM. Groundwater sample results for 2010 are summarized in Table B-20.
In summary, the levels of radionuclides in the environment surrounding Indian Point were within the historical ranges, i.e., previous levels resulting from natural and anthropogenic sources for the detected radionuclides. Further, Indian Point operations in 2010 did not result in exposure to the public greater than environmental background levels.

SECTION 2 INTRODUCTION
2.0 INTRODUCTION
2.1 Site Description The Indian Point site occupies 239 acres on the east bank of the Hudson River on a point of land at Mile Point 42.6. The site is located in the Village of Buchanan, Westchester County, New York. Three nuclear reactors, Indian Point Unit Nos. 1, 2 and 3, and associated buildings occupy approximately 35 acres. Unit 1 has been retired as a generating facility. Units 1, 2, and 3 are owned and operated by Entergy Nuclear.
2.2 Program Background Environmental monitoring and surveillance have been conducted at Indian Point since 1958, which was four years prior to the start-up of Unit 1. The pre-operational program was designed and implemented to determine the background radioactivity and to measure the variations in activity levels from natural and other sources in the vicinity, as well as fallout from nuclear weapons tests. Thus, as used in this report, background levels consist of those resulting from both natural and anthropogenic sources of environmental radioactivity. Accumulation of this background data permits the detection and assessment of environmental activity attributable to plant operations.
2.3 Program Objectives The current environmental monitoring program is designed to meet two primary objectives:
- 1. To enable the identification and quantification of changes in the radioactivity of the area, and
- 2. To measure radionuclide concentrations in the environment attributable to operations of the Indian Point site.
To identify changes in activity, the environmental sampling schedule requires that analyses be conducted for specific environmental media on a regular basis. The radioactivity profile of the environment is established and monitored through routine evaluation of the analytical results obtained.
The REMP designates sampling locations for the collection of environmental media for analysis. These sample locations are divided 2-1
into indicator and control locations. Indicator locations are established near the site, where the presence of environmental radioactivity of plant origin is most likely to be detected. Control locations are established farther away (and upwind/upstream, where applicable) from the site, where the level would not generally be affected by plant discharges.
The use of indicator and control locations enables the identification of potential sources of detected radioactivity, thus meeting one of the program objectives.
Verification of expected radionuclide concentrations resulting from effluent releases attributable to the site is another program objective.
Verifying projected concentrations through the REMP is difficult since the environmental concentrations resulting from plant releases are consistently too small to be detected. Plant related radionuclides were detected in 2010; however, residual radioactivity from atmospheric weapons tests and naturally occurring radioactivity were the predominant sources of radioactivity in the samples collected. Analysis of the 2010 REMP sample results confirms that radiological effluents were well below regulatory limits.

SECTION 3 PROGRAM DESCRIPTION
3.0 PROGRAM DESCRIPTION To achieve the objectives of the REMP and ensure compliance with the ODCM, sampling and analysis of environmental media are performed as outlined in Table A-1 and described in section 3.3.
3.1 Sample Collection Entergy personnel perform collection of environmental samples for the Indian Point site, with the exception of groundwater and fish/invertebrate samples.
The groundwater (monitoring well) samples are collected by a contracted environmental vendor, GZA Geo Environmental, Inc.
Assistance in the collection of fish and invertebrate samples was provided by a contracted environmental vendor - Normandeau Associates, Inc.
3.2 Sample Analysis The analysis of Indian Point environmental samples is performed by the James A. Fitzpatrick Nuclear Power Plant (JAFNPP) Environmental Laboratory in Fulton, New York. The JAFNPP lab at Fulton currently analyzes nearly all samples, except for groundwater samples and some tritium, nickel and strontium analyses on other media. These samples were analyzed at other New York State Department of Health Environmental Laboratory Approval Program (ELAP) certified laboratories.
3.3 Sample Collection and Analysis Methodology 3.3.1 Direct Radiation Direct gamma radiation is measured using integrating calcium sulfate thermoluminescent dosimeters (TLDs), which provide cumulative measurements of radiation exposure (i.e., total integrated exposures in milli-roentgen, mR) for a given period. The area surrounding the Indian Point site is divided into 16 compass sectors. Each sector has two TLD sample locations. The inner ring is located near the site boundary at approximately 1 mile (1.6 km). The outer ring is located at approximately 5 miles (8 km) from the site (6.7- 8.0 km), see Figures A-1 and A-2.
3-1
An additional TLD sample site is located at Roseton (20.7 miles north) as a control, and there are eight other TLD sample locations of special interest.
In total, there are 41 TLD sample sites, designated DR-1 through DR-41, with two TLDs at each site. TLDs are collected and processed on a quarterly basis. The results are reported as mR per standard quarter (91 days). The mR reported is the average of the two TLDs from each sample site.
3.3.2 Airborne Particulates and Radioiodine Air samples were taken at eight locations varying in distance from 0.28 to 20.7 miles (0.4 to 33 km) from the plant. These locations represent one control at sampling station 23 (AM) and seven indicator locations.
These indicator locations are at sampling stations 4 (Al), 5 (A4), 27, 29, 44, 94 (A2), and 95 (A3). The locations are shown on Figures A-i, A-2, and A-3. The air samples are collected continuously by means of fixed air particulate filters followed by in-line charcoal cartridges. Both are changed on a weekly basis. The filter and cartridge samples are analyzed for gross beta and radioiodine, respectively. In addition, gamma spectroscopy analysis (GSA) is performed on quarterly composites of the air particulate filters.
3.3.3 Hudson River Water Hudson River water sampling is performed continuously at the intake structure (sampling station 9, Wal) and at a point exterior to the discharge canal where Hudson River water and water from the discharge canal mix (sampling station 10, Wa2); see Figure A-1. An automatic composite sampler is used to take representative samples.
On a weekly basis, accumulated samples are taken from both sample points. These weekly river water samples are composited for monthly gamma spectroscopy analysis, and quarterly for tritium analysis.
3.3.4 Drinking Water Samples of drinking water are collected monthly from the Camp Field Reservoir (3.4 miles NE, sample station 7, sample designation Wbl) and New Croton Reservoir (6.3 Mi SE, sample station 8); see Figure A-
- 3. Each monthly sample is approximately 4 liters and is analyzed for gamma-emitting radionuclides. They are also composited quarterly and analyzed for tritium.
3-2
3.3.5 Hudson River Shoreline Soil Shoreline soil samples are collected at three indicator and two control locations along the Hudson River. The indicator locations are at sampling stations 53 (Wcl), 28, and 17. The control locations are at sampling stations 50 (Wc2) and 84. Figures A-1, A-2, and A-3 show these locations. The samples are gathered at a level above low tide and below high tide and are approximately 2-kg grab samples. These samples are collected at greater than 90 days apart and are analyzed by gamma spectroscopy and for strontium-90.
3.3.6 Broad Leaf Vegetation Broad leaf vegetation samples are collected from three locations during the growing season. The indicator locations are sampling stations 94 (Ic2) and 95 (Icl), and the control location is at Roseton, sampling station 23 (Ic3).
See Figures A-1 and A-2. The samples are collected monthly, when available, and analyzed by gamma spectroscopy. These samples consist of at least 1 kg of leafy vegetation and are used in the assessment of the food product and milk ingestion pathways.
3.3.7 Fish and Invertebrates Fish and invertebrate samples are obtained from the Hudson River at locations upstream and downstream of the plant discharge. The indicator location (downstream sample point) is designated as sampling station 25 (Iblb) and the control location (upstream) is at Roseton, sampling station 23 (Wb2). See Figures A-1 and A-2. These samples are collected in season or semiannually if they are not seasonal. The fish and invertebrates sampled are analyzed by gamma spectroscopy, for Sr-90 and for Ni-63.
3.3.8 Hudson River Aquatic Vegetation During the spring and summer, aquatic vegetation samples are collected from the Hudson River at two indicator locations (sampling stations 17 and 28) and one control location (84); see Figure A-3.
Samples of aquatic vegetation are obtained depending on sample availability. These samples are analyzed by gamma spectroscopy.
3-3
3.3.9 Hudson River Bottom Sediment Bottom sediment and benthos are sampled at four locations: three indicator locations (sampling stations 10, 17, and 28) and one control location (84), along the Hudson River, once each spring and summer; see Figure A-3. These samples are obtained using a Peterson grab sampler or similar instrument. The bottom sediment samples are analyzed by gamma spectroscopy.
3.3.10 Precipitation Precipitation samples are continuously collected at one indicator location (sampling station 44) and one control location (23); see Figure A-3. They are collected in sample bottles designed to hinder evaporation. They are composited quarterly and analyzed for tritium.
They are also analyzed by gamma spectroscopy.
3.3.11 Soil Soil samples are collected from two indicator locations (sampling stations 94 and 95), and one control location (23) on an annual basis; see Figure A-3. They are approximately 2 kg in size and consist of about twenty 2-inch deep cores. The soil samples are analyzed by gamma spectroscopy.
3.3.12 Groundwater Samples Based on recent site hydrology evaluations and the addition of a number of groundwater sampling wells, two monitoring wells were installed in 2006 and designated as REMP sample stations 104 (MW-
- 40) and 105 (MW-51). These wells have sample points at six different elevations which were specifically designed to be representative of groundwater moving towards the site boundary. In 2010, an offsite well at the Lafarge plant (106) was established to replace MW-40 and MW-
- 51. This groundwater sample location is shown in Figure A-3.
Groundwater samples at location were obtained semi-annually at Lafarge (106.) Samples are analyzed for tritium, Sr-90, Ni-63 and by gamma spectroscopy.
3.3.13 Land Use Census Each year a land use census consisting of milch animal and residence surveys is conducted during the growing season to determine the current utilization of land within 5 miles (8 km) of the site. These 3-4
surveys are used to determine whether there are changes in existing conditions that warrant changing the sampling program.
For example, the milch animal census is used to identify animals producing milk for human consumption within 5 miles (8 km) of Indian Point. This census consists of visual field surveys of the areas where a high probability of milch animals exists and confirmation through personnel such as feed suppliers who deal with farm animals and dairy associations (See Tables B-21 and B-22).
Visual inspections were made of the 5-mile area around the Indian Point Site during routine sample collections and emergency plan equipment inspections in the area throughout the year. An extensive land survey was conducted of the 5-mile area in an attempt to identify new residential areas, commercial developments and to identify milch animals in pasture. Previous locations were visited and verified by dispatching Nuclear Environmental Technicians to the various locations.
Note: These actions were taken while performing quarterly environmental badge change out and field inspections through out the four surrounding counties.
- Orange County was surveyed during through the summer and fall.
- Rockland County was surveyed during summer and fall.
- Putnam County was surveyed during the summer and fall.
- Westchester County was surveyed during the spring, summer and fall.
Although there are presently no animals producing milk for human consumption within 5 miles (8 km) of the site, the census is performed to determine if a milk-sampling program needs to be conducted.
A residence census is also performed to identify the nearest residence(s) to the site in each of the 16 sectors surrounding Indian Point. See Table B-22.
A garden census was not performed, as the ODCM allows sampling of vegetation in two sectors near the site boundary in lieu of a garden census. The sectors are chosen to be in the pre-dominant wind directions.
3-5
Note: An aerial survey was not conducted of the 5-mile area this year.
3.4 Statistical Methodology There is a number of statistical calculation methodologies used in evaluating the data from the Indian Point REMP. These methods include determination of Lower Limits of Detection (LLD) and Critical Levels (L,), and estimation of the mean and associated propagated error.
3.4.1 Lower Limit of Detection (LLD) and Critical Level (Lc The LLD is the smallest concentration of radioactive material ina sample that will be detected with 95% probability with 5%probability of falsely concluding that a blank obser-ation represents a "real" signal.
For a particular measurement system (which may include radiochemical separation):
2.71 1 '-3.29s * 'I -
LLD,- T where:
LLD = The lower limit of detection as defined above (as picocurie per unit mass or volume)
T = The sample countng time in minutes so = The standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute)
T, = The background count time in minutes E= The counting efficiency (as counts per transformation)
V= The sample size (in units of mass or volume) k= A constant for the number of transformations per minute per unit of activity (normally, 2-22E+6 dpm per 1LCi)
Y The fractional radiochemical yield (-when applicable) 3-6
,= The radioactive decay constant for the particular radionuclide t= The elapsed time between midpoint of sample collection and time of counting Note: The above LLD formula accounts for differing background and sample count times.
The Radiological Environmental Monitoring Program, REMP, uses an LLD formula that assumes equal background and sample count times, in accordance with the RECS.
When the above LLD formula is more appropriate for the effluents program, it may be used.
The constants 2.71 and 3.29 and the general LLD equation vwere derived from the following two sources:
- 1) Currie, L.A. "Limits for Qualitative Detection of Quantitative Determination". (Anal. Chem.
40:586-593, 1968); and,
- 2) Mayer, Dauer "Application of Systematic Error Bounds to Detection Limits for Practical Counting".
(HP Journal 65(1): 89-91, 1993)
The value of Sb used in the calculation of the LLD for a detection system shall be based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gamma ray spectrometry, the background shall include the typical contributions of other radionuclides nomally present in the samples. Typical values of E, V, Y, and t shall be used in the calculation. The background count rate is calculated from the background counts that are detemlined to be within + one F-MHM (Full-Width-at-Half-Maximum) energy band about the energy of the gamma ray peak used for the quantitative analysis for that radionuclide.
It should be recognized that the LLD is defined as an a orio (before the fact) limit representing the capability of a measurement process and not as an a posteriori (after the fact) limit for a particular measurement-To handle the a postenori problem, adecision level must be defined, which has been identified as the Critical Level. Following an experimental observation, one must decide whether or not a real signal was, in fact, detected. This type of binary qualitative decision is subject to two kinds of error:
deciding that the radioactive material is present when it is not (a: Type I error), and the converse, failing to decide that it is present when it is (b: Type It error). The maximum acceptable Type I error (a), together with the standard deviation, Snet, of the net signal when the net signal equals zero, establish the Critical Level, Lc, upon which decisions may be based.
Operationally, an observed signal, S, must exceed L: to yield the decision, detected.
Le kas*(+Tf)'sf where:
k, is related to the standardized normal distribution and corresponds to a probability level of 1-a.
For instance, selection of a = 0.01 corresponds to a 99%/6 confidence level that activity is present.
When determining the Lc for different measurement processes, it is allowable to set a at less than or equal to 0.05 as long as the following condition is met:
To set a for Lc determination at less than 0.05, the equation for the LLD (which places a less than or equal to 0.05) should be employed to verify that the calculated LLD is less than or equal to the LLDs specified in the RECS. This calculation, ifnecessary, will be performed on a case by case basis.
3-7
3.4.2 Determination of Mean and Propagated Error In accordance with program policy, recounts of positive samples are performed. When the initial count reveals the presence of radioactivity, which may be attributed to plant operations, at a value greater than the Lc, two recounts are performed to verify the positive results. The recounts are not performed on; air samples with positive results from gross beta analysis, since the results are always positive due to natural background radioactive material in the air, or tritium in water samples, since an outside contractor provides these activities. When a radionuclide is positively identified in two or more counts, the analytical result for the radionuclide is reported as the mean of the positive detections and the associated propagated error for that mean. In cases where more than one sample result is available, the mean of the sample results and the estimated error for the mean are reported in the Annual Report.
The mean (X) and the propagated error (PE) are calculated using the following equations:
N Exi X= i=1 N
where: Xi value of each individual observation N number of observations Z(ERRX)
PE = =
N where: ERRN = 1 sigma error of the individual analysis N = number of observations 3.4.3 Table Statistics The averages shown in the summary table (Table B-2) are the averages of the positive values in accordance with the NRC's Branch Technical Position (BTP) to Regulatory Guide 4.8 (Reference 14).
Samples with "<" values are not included in the averages.
3-8
It should be noted that this statistic for the mean using only positive values tends to strongly bias the average high, particularly when only a few of the data are measurably positive. The REMP data show few positive values; thus the corresponding means are biased high.
Exceptions to this include direct radiation measured by TLDs and gross beta radioactivity in air, which show positive monitoring results throughout the year.
In the data tables B-6 through B-20, values shown are based on the Lc value, unless otherwise noted. If a radionuclide was detected at or above the Lc value in two or more counts, the mean and error are calculated as per Section 3.4.2, and reported in the data table. Values listed as "<" in the data tables are the Lc values for that sample, unless otherwise noted. If multiple counts were performed on a sample and a radionuclide's values are "< L, " each time, the largest critical level is reported in the data table.
The historical data tables contain the annual averages of the positive values for each year. The historical averages are calculated using only the positive values presented for 2000 through 2009. The 2010 average values are included in these historic tables for purposes of comparison.

SECTION 4 RESULTS AND DISCUSSION
4.0 RESULTS AND DISCUSSION The 2010 Radiological Environmental Monitoring Program (REMP) was conducted in accordance with Indian Point's Offsite Dose Calculation Manual ODCM. The ODCM contains requirements for the number and distribution of sampling locations, the types of samples to be collected, and the types of analyses to be performed for measurement of radioactivity.
The REMP at Indian Point includes measurements of radioactivity levels in the following environmental pathways.
Hudson River Water Shoreline Soil Fish and Invertebrates Aquatic Vegetation Bottom Sediment Airborne Particulates and Radioiodine Precipitation Drinking Water Terrestrial Broad Leaf Vegetation Direct Gamma Radiation Soil Groundwater An annual land use and milch animal census is also part of the REMP.
To evaluate the contribution of plant operations to environmental radioactivity levels, other man-made and natural sources of environmental radioactivity, as well as the aggregate of past monitoring data, must be considered. It is not merely the detection of a radionuclide, but the evaluation of the location, magnitude, source, and history of its detection that determines its significance. Therefore, we have reported the data collected in 2010 and assessed the significance of the findings.
A summary of the results of the 2010 REMP is presented in Table B-2. This Table lists the mean and range of all positive results obtained for each of the media sampled at ODCM indicator and control locations. Discussions of these results and their evaluations are provided below.
The radionuclides detected in the environment can be grouped into three categories: (1) naturally occurring radionuclides; (2) radionuclides resulting from weapons testing and other non-plant related, anthropogenic sources; and (3) radionuclides that could be related to plant operations.
4-1
The environment contains a broad inventory of naturally occurring radionuclides which can be classified as, cosmic ray induced (e.g., Be-7, H-
- 3) or geologically derived (e.g., Ra-226 and progeny, Th-228 and progeny, and K-40.) These radionuclides constitute the majority of the background radiation source and thus account for a majority of the annual background dose detected. Since the detected concentrations of these radionuclides were consistent at indicator and control locations, and unrelated to plant operations, their presence is noted only in the data tables and will not be discussed further.
The second group of radionuclides detected in 2010 consists of those resulting from past weapons testing in the earth's atmosphere. Such testing in the 1950's and 1960's resulted in a significant atmospheric radionuclide inventory, which, in turn, contributed to the concentrations in the lower atmosphere and ecological systems. Although reduced in frequency, atmospheric weapons testing continued into the 1980's. The resultant radionuclide inventory, although diminishing with time (e.g., through radioactive decay and natural dispersion processes), remains detectable.
In 2010, the detected radionuclide that may be attributable to past atmospheric weapons testing consisted of Cs-137 in some media. The levels detected were consistent with the historical levels of radionuclides resulting from weapons tests as measured in previous years.
The final group of radionuclides detected through the 2010 REMP comprises those that may be attributable to current plant operations. During 2010 Cs-137 and tritium (H-3) were the only potentially plant-related radionuclides detected in some environmental samples.
H-3 may be present in the local environment due to either natural occurrence, other man-made sources, or as a result of plant operations.
Cs-137 is produced in and released from fission reactors and were introduced into the environment from the accident at Chernobyl in 1986. Cs-137 is ubiquitous in the environment from atmospheric testing debris and a lesser amount from the Chernobyl accident. In 2010, there were three detections of Cs-137 in shoreline soil (2 indicator samples and one control sample). In bottom sediment there were five positive detections of Cs-1 37 (all at indicator stations or near to plant.) The two discharge canal samples are consistent with historical values.
A sample of aquatic vegetation at Lents Cove showed Cs-1 37 activity greater than the critical level but less that the lower limit of detection. It is being reported positive, due to its relation to the critical level, but not significant. A sample at Cold Spring (distant location) showed detectable, but not 4-2
significant, Cs-137 activity. The level is the same as that found at Lents Cove.
The fact that there was no Cs-134 present (recent plant releases would contain Cs-134) and that there was detection also at a distant location indicates that the activity may be due to atmospheric weapons testing, with some contribution from plant releases from several years past.
Strontium-90 (Sr-90) may also be present in the environment from atmospheric testing debris. Due to a desire to improve the sensitivity of Sr-90 in environmental samples, a new analytical technique was pursued, at the end of 2009, for application in 2010.
2009 fish/invertebrate sample results for Sr-90 were inconclusive. As noted in the 2009 AREOR, the results for Sr-90 in all fish and invertebrate samples were under review and not reliable. It was noted that when the certified results were available, they would be submitted as an addendum.
However, as detailed below, no certifiable results were able to be obtained from the 2009 samples. In a letter dated June 29, 2010, the laboratory identified that due to the extremely low detection level requested, interferences such as radon progeny rendered the 2009 data invalid. Close observation of the analytical method used in 2009 identified the need to improve the technique, to better screen out these contaminants, or proceed in another way. A new technique was adopted at the end of 2009's evaluation, for application in 2010.
An attempt was made to re-analyze 2009 fish/invertebrate samples for Sr-90 using the new method, but.the media had been consumed in the earlier tests and no further analyses were possible. 2010 samples were analyzed with the new method, with much improved sensitivity and reliability. No Strontium-90 was identified in samples from 2010.
1-131 is also produced in fission reactors, but can result from non-plant related anthropogenic sources, e.g., medical administrations, such as in previous years. 1-131 was not detected in 2010 in aquatic vegetation indicator and control locations.
Co-58 and Co-60 are activation/corrosion products also related to plant operations. They are produced by neutron activation in the reactor core. As Co-58 has a much shorter half-life, its absence "dates" the presence of Co-60 as residual from releases of both radionuclides in the past. If Co-58 and Co-60 are concurrently detected in environmental samples, then the source of these radionuclides is considered to be from recent releases.
When significant concentrations of Co-60 are detected but no Co-58, there is an increased likelihood that the Co-60 is due to residual Co-60 from past 4-3
operations. There was no Co-58 or Co-60 detected in the 2010 REMP, though they (Co-58 and Co-60) can be observed in historical data.
In the following sections, a summary of the results of the 2010 REMP is presented by sample medium and the significance of any positive findings discussed. It should be noted that naturally occurring radionuclides are omitted from the summary table (Table B-2) and further discussion.
4.1 Direct Radiation The environmental TLDs used to measure the direct radiation were TLDs supplied and processed by AREVA NP via the JAF Laboratory.
In 2010, the TLD program produced a consistent picture of ambient background radiation levels in the vicinity of the Indian Point Station. A summary of the annual TLD data is provided in Table B-2 and all the TLD data are presented in Tables B-3, B-4 and B-5. TLD sample site DR-40 is the control site for the direct radiation (DR) series of measurements.
Table B-3 provides the quarterly and annual average reported doses in mR per standard quarter for each of the direct radiation sample points, DR-1 through DR-41. The table also provides the sector for each of the DR sample points. Table B-4 provides the mean, standard deviation, minimum and maximum values in mR per standard quarter for the years 2000 through 2008. The 2010 means are also presented in Table B-4. Table B-5 presents the 2010 TLD data for the inner ring and outer ring of TLDs.
The 2010 mean value for the direct radiation sample points was 14.0 mR per standard quarter - which represents no change from 2009. At those locations where the 2010 mean value was higher than historical means, they are within historical bounds for the respective locations.
The DR sample locations are arranged so that there are two concentric rings of TLDs around the Indian Point site. The inner ring (DR-1 to DR-
- 16) is close to the site boundary. The outer ring (DR-17 to DR-32) has a radius of approximately 5 miles from the three Indian Point units. The results for these two rings of TLDs are provided in Table B-5. The annual average for the inner ring was 14.0 mR per standard quarter and also average for the outer ring was 14.3 mR per standard quarter.
The control location average for 2010 was 13.0 mR per standard quarter.
Table C-1 and Figure C-1 present the 10-year historical averages for the inner and outer rings of TLDs. The 2010 averages are consistent with the historical data. The 2010 and previous years' data show that 4-4
there is no measurable direct radiation in the environment due to the operation of the Indian Point site.
4.2 Airborne Particulates and Radioiodine An annual summary of the results of the 2010 air particulate filter and charcoal cartridge analyses is presented in Table B-2. As shown, there were no radionuclides detected in the air attributable to plant operations.
The results of the analyses of weekly air particulate filter samples for gross beta activity are presented in Table B-6, and the results of the gamma spectroscopy analyses of the quarterly composites of these samples are in Table B-7.
Gross beta activity was found in air particulate samples throughout the year at all indicator and control locations. The average gross beta activity for the eight indicator air sample locations was 0.013 pCi/m 3 and the average for the control location was 0.013 pCi/m 3 . The activities detected were consistent for all locations, with no significant differences in gross beta activity in any sample due to location. Gamma spectroscopy analyses of the quarterly composite air samples showed that no reactor-related radionuclides were detected and that only naturally-occurring radionuclides were present at detectable levels.
The mean annual gross beta concentrations and Cs-137 concentrations in air for the past 10 years are presented in Table C-2. From this table and Figure C-2, it can be seen that the average 2010 gross beta concentration was consistent with historical levels. Cs-137 has not been detected since 1987. This is consistent with the trend of decreasing ambient Cs-1 37 concentrations in recent years.
The charcoal cartridge analytical results are presented in Table B-8.
"Less than" values are presented as sample critical level (Lc). There was no 1-131 detected (LLD = 0.07 pCi/mi3 ) in the charcoal cartridge samples, which is consistent with historical trends.
From the data, it can be seen that no airborne radioactivity attributable to the operation of Indian Point was detected in 2010.
4.3 Hudson River Water A summary of the radionuclides detected in the Hudson River water is contained in Table B-2. Data resulting from analysis of monthly Hudson River water samples for gamma emitters, and H-3 analysis of quarterly composites, are presented in Tables B-9 and B-10, respectively.
4-5
Only H-3 was found. The levels are consistent with occasional historical detection of H-3. Additionally, Table C-3 indicates the absence of Cs-137 which is consistent with historical data.
4.4 Drinking Water The annual program summary table (Table B-2) contains a summary of the 2010 drinking water sample analysis results. Results of the gamma spectroscopy analyses of the monthly drinking water samples are in Table B-11 and results of tritium analysis of quarterly composites are in Table B-12. Other than naturally occurring radionuclides, no radionuclides were detected in drinking water samples.
A summary and illustration of historic trends of drinking water are provided in Table C-4 and Figure C-4, respectively. An examination of the data indicates that operation of the Indian Point units had no detectable radiological impact on drinking water.
4.5 Hudson River Shoreline Soil A summary of the radionuclide concentrations detected in the shoreline soil samples is contained in Table B-2. Table B-13 contains the results of the gamma spectroscopic and strontium-90 analyses of the shoreline soil samples.
In addition to the naturally occurring radionuclides, Cs-137 was identified in the Hudson River shoreline soil samples in 2010. Cs-137 was detected at the Verplanck location in both samples from that location, for a total of two positive values out of eight samples from indicator locations. Cs-137 was detected at the control location (Manitou Inlet) in one of two samples (63 pCi/kg). The average concentration for the indicator locations that had positive indication of Cs-137 was 154 pCi/kg (dry) with a maximum concentration of 174 pCi/kg (dry.)
An historical look at Cs-137 detected in shoreline soil at indicator and control locations can be viewed in Table C-5 and Figure C-5. Cs-137 has been and continues to be present in this media, both at indicator and control locations, at a consistent level over the past ten years.
Cs-134 and Cs-137 are both discharged from the plant in similar quantities. The lack of Cs-134 activity is an indication that the primary source of the Cs-137 in the shoreline soil is legacy contamination from weapons fallout.
4-6
No Sr-90 was detected in any collected shoreline soil samples.
4.6 Broad Leaf Vegetation Table B-2 contains a summary of the broad leaf vegetation sample analysis results. Data from analysis of the 2010 samples are presented in Table B-14. Analyses of broad leaf vegetation samples revealed only one instance of Cs-1 37 at 31 pCi/kg (wet) value.
Table C-6 contains an historical summary and Figure C-6 is an illustration of the broad leaf vegetation analysis results. The detection of low levels of Cs-137 has occurred sporadically at both indicator and control locations at relatively low concentrations for the past ten years and not at all in the last five years. The 2010 single detection is comparable to the highest average positive detection of the last ten years.
4.7 Fish and Invertebrates A summary of the fish and invertebrate sample analysis results is presented in Table B-2. Table B-15 contains the results of the analysis of fish and invertebrate samples for 2010. There were no plant related radionuclides detected as a result of the GSA.
Strontium-90 was added to the analyte list in 2007. Ni-63 was added with an ODCM revision in 2010. No Ni-63, Sr-90 or any other activity aside from naturally-occurring ones was found in any of these samples in 2010. An improved analytical method for Strontium-90 in fish/invertebrates was applied in 2010, improving the sensitivity, and reducing analytical error. This improved analytical technique gave us the required sensitivity and reliable results.
A summary of historical fish and invertebrate analytical data is presented in Table C-7 and illustrated in Figure C-7. Available data are consistent with historical trends.
4.8 Aquatic Vegetation A summary of the aquatic sample analysis results is presented in Table B-2. Table B-16 contains the results of the analysis of aquatic vegetation samples for 2010.
The laboratory reported positive Cs-137 (17.6 pCi/kg) at Lents Cove.
This is an amount between the Critical Level and the LLD. Activity-free samples would, about 5% of the time, show a positive result due to normal background statistical fluctuations. In the historical record, a 17 4-7
pCi/kg result was reported for a 2005 aquatic vegetation sample and also one for 2009 at the same location. A comparable detection at the Cold Spring control location showed 16.8 pCi/kg - a quite similar result.
There are about five samples per year, varying from 3 to 10, going back to 2005. No 1-131 was detected.
4.9 Hudson River Bottom Sediment A summary of the Hudson River bottom sediment analysis results is presented in Table B-2. Table B-17 contains the results of the analysis of bottom sediment samples for 2010. Cs-137 was detected at 5 of 6 indicator station samples and not at all at two control station samples.
This frequency of detection is not unusual. Cs-1 34 was not detected in any bottom sediment samples. The lack of Cs-134 suggests that the primary source of the Cs-137 in bottom sediment is from historical plant releases over the years and from residual weapons test fallout.
The discharge canal bottom sediments were 418 pCi/kg and 1330 pCi/kg on samples taken three months apart (average = 874 pCi/kg.).
There is nothing in release data and in monitoring well data that corresponds to this difference. The results are very comparable to the 2009 results - thus corroborating the 2009 results. The average of all indicator detections is 553 pCi/kg (493 pCi/kg in 2009.) This is consistent with historical annual average concentration for indicator locations.
This detection of Cs-137 in bottom sediment generally decreased from an average of 1200 pCi/kg in the early 1990s to 500 pCi/kg in the mid-1990s to a recent value of about 430 pCi/kg. Cs-134 has not been detected in bottom sediment since 2002.
4.10 Precipitation A summary of the precipitation sample analysis results is presented in Table B-2. Table B-18 contains the results of the precipitation samples for 2010. Other than naturally occurring radionuclides, no radionuclides were detected in precipitation samples.
A review of historical data over the last 10 years indicates tritium had been detected in both indicator and control precipitation samples in 2000; however, there have been no instances of positive values since that time.
4-8
4.11 Soil A summary of the soil sample analysis results is presented in Table B-
- 2. Table B-19 contains the results of the soil samples for 2010. Other than naturally occurring radionuclides, no activity was detected in any of the soil samples.
4.12 Groundwater A summary of the groundwater samples for 2010 is contained in Table B-2. Data resulting from analysis of the groundwater samples for gamma emitters, tritium analysis, and Sr-90 are given in Table B-20.
No REMP nuclides other than naturally occurring ones were found in 2010.
4.13 Land Use Census A census was performed in the vicinity of Indian Point in 2010. This census consisted of a milch animal and a residence census. Results of this census are presented in Tables B-21 and B-22.
The results of the 2010 census were generally same as the 2007 census results. The New York Agricultural Statistic Service showed there were no animals producing milk for human consumption found within 5 miles (8 km) of the plant. Field observations also yielded no milching animal locations within five miles.
The second part of this census revealed that the two nearest residences in different sectors are located 0.44 miles (0.71 km) ESE and 0.73 miles (1.13 km) S of the plant. The 2010 land use census indicated there were no new residences that were closer in proximity to IPEC.
The ODCM allows the sampling of broad leaf vegetation in two sectors at the site boundary in lieu of performing a garden census. Analysis results for these two sectors are discussed in Section 4.6 and presented in Table B-14, Table C-6 and Figure C-6.
4.14 Conclusion The Radiological Environmental Monitoring Program is conducted each year to determine the radiological impact of Indian Point operations on the environment. The preceding discussions of the results of the 2010 REMP reveal that operations at the station did not result in an adverse impact on the environment.
4-9
The 2010 REMP results demonstrate the relative contributions of different radionuclide sources, both natural and anthropogenic, to the environmental concentrations. The results indicate that the fallout from previous atmospheric weapons testing continues to contribute to detection of Cs-137 in some environmental samples. There are infrequent detections of plant related radionuclides in the environs; however, the radiological effects are very low and are significantly less than those from natural background and other anthropogenic sources.

APPENDIX A ENVIRONMENTAL SAMPLING AND ANALYSIS REQUIREMENTS
APPENDIX A Environmental media are sampled at the locations specified in Table A-1 and shown in Figures A-i, A-2, and A-3. The samples are analyzed according to criteria established in the ODCM. These requirements include: methods of sample collection; types of sample analysis; minimum sample size required; lower limit of detection, which must be attained for each medium, sample, or analysis type, and environmental concentrations requiring special reports.
Table A-1 provides the sampling station number, location, sector, and distance from Indian Point, sample designation code, and sample type. This table gives the complete listing of sample locations used in the 2010 REMP.
Three maps are provided to show the locations of REMP sampling. Figure A-1 shows the sampling locations within two miles of Indian Point. Figures A-2 and A-3 show the sampling locations within ten miles of Indian Point.
The ODCM required lower limits of detection (LLD) for Indian Point sample analyses are presented in Table A-2. These required lower limits of detection are not the same as the lower limits of detection or critical levels actually achieved by the laboratory. The laboratory's lower limits of detection and critical levels must be equal to or lower than the required levels presented in Table A-2.
Table A-3 provides the reporting level for radioactivity in various media. Sample results that exceed these levels and are due to plant operations require that a special report be submitted to the NRC.
In addition to the sampling outlined in Table A-I, there is an environmental surveillance requirement that an annual land use and milch animal census be performed. See Tables B-21 and B-22 for the milch animal and land use census.

TABLE A-2 LOWER LIMIT OF DETECTION (LLD) REQUIREMENTS FOR ENVIRONMENTAL SAMPLES (a) This list does not mean that only these nuclides are to be considered. Other peaks that are identifiable, together with those of the above nuclides, shall also be analyzed and reported in the Annual Radiological Environmental Operating Report pursuant to Specification D 5.1.
(b) Required detection capabilities for them~oluminescent dosimeters used for environmental measurements are given in Regulatory Guide 4.13.
(c) The LLD is defined as the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will be detected with 95% probability with only 5% probability of falsely concluding that a blank observation represents a "real" signal.
It should be recognized that the LLD is defined as an a Enori (before the fact) limit representing the capability of a measurement system and not as an a ppsteriori (after the fact) limit for a particular measurement. Analyses shall be perfonrned in such a manner that the stated LLDs A11 be achieved under routine conditions. Occasionally background fluctuations, unavoidable small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors shall be identified and described in the Annual Radiological Environmental Operating Report pursuant to RECS D 5.1.
(d) These LIDs are for drinking water samples. If no drinking water pathway exists, the LLDs may be increased to 3.000 for H-3 and 15 for l-131.
(e) These required lower limits of detection are associated only with the REMP requirements. The Radiological Ground Water Monitoring Program may involve unique reportiuig level criteria, independent of the REMP, and defined in station procedures.
(f) Sr-90 and Ni-63 are included in this table due to their historical presence in ground water and possible migration to the environment, per References 45 and 46.

APPENDIX B RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM RESULTS
SUMMARY
APPENDIX B B,1 2010 Annual Radiological Environmental Monitoring Program Summary The results of the 2010 radiological environmental sampling program are presented in Tables B-2 through B-20. Table B-2 is a summary table of the sample results for 2010. The format of this summary table conforms to the reporting requirements of the ODCM, NRC Regulatory Guide 4.8 (Reference 4),
and NRC Branch Technical Position to Regulatory Guide 4.8 (Reference 14). In addition, the data obtained from the analysis of samples are provided in Tables B-3 through B-20.
REMP samples were analyzed by various counting methods as appropriate.
The methods are; gross beta, gamma spectroscopy analysis, liquid scintillation, radiochemical analysis, and TLD processing. Gamma spectroscopy analysis was performed for the following radionuclides; Be-7, K-40, Mn-54, Co-58, Co-60, Fe-59, Zn-65, Zr-95, Nb-95, Ru-103, Ru-106, 1-131, Cs-134, Cs-137, Ba/La-140, Ce-141, Ce-144, Ra-226 and Ac/Th-228. Radiochemical analyses were performed for 1-131, Ni-63 and Sr-90 for specific media and locations as required in the ODCM.
B.2 Land Use Census In accordance with Sections IP2-D3.5.2 and IP3-2.8 of the ODCM, a land use census was conducted to identify the nearest milch animal and the nearest residence. The results of the milch animal and land use census are presented in Tables B-21 and B-22, respectively. In lieu of identifying and sampling the nearest garden of greater than 50 M 2 , at least- three kinds of broad leaf vegetation were sampled near the site boundary in two sectors and at a designated control location (results are presented in Table B-14).
B.3 Sampling Deviations During 2010, environmental sampling was performed for 12 unique media types addressed in the ODCM and for direct radiation. A total of 1166 samples of 1178 scheduled were obtained. Of the scheduled samples, 99.0% were collected and analyzed for the program. Sampling deviations are summarized in Table B-1; discussions of the reasons for the deviations are provided in Table B-ia for air samples, B-i b for TLDs and B-ic for other environmental media.
B.4 Analytical Deviations There were no analytical deviations in 2010.
Note: in 2009, twenty-three suspect analyses for Sr-90 in fish resulted in incomplete results for this radionuclide. The vendor's method for analyzing the fish for Sr-90 was inadequate for the required sensitivity. Accordingly, the vendor B-1
and the method of analysis were changed for 2010. All analyses for Sr-90 in 2010 fish were successfully performed and the required sensitivity was met.
B.5 Special Reports No special reports were required under the REMP.

APPENDIX C HISTORICAL TRENDS
APPENDIX C The past ten years of historical data for various radionuclides and media are presented both in tabular form and in graphical form to facilitate the comparison of 2010 data with historical values. Although other samples were taken and analyzed, values were only tabulated and plotted where positive indications were present.
Averaging only the positive values in these tables can result in a biased high value, especially, when the radionuclide is detected in only one or two quarters for the year.

APPENDIX D INTERLABORATORY COMPARISON PROGRAM
D.1 PROGRAM DESCRIPTION The Offsite Dose Calculation Manual (ODCM), Part 1, Section 5.3 requires that the licensee participate in an Interlaboratory Comparison Program. The Interlaboratory Comparison Program shall include sample media for which samples are routinely collected and for which comparison samples are commercially available. Participation in an Interlaboratory Comparison Program ensures that independent checks on the precision and accuracy of the measurement of radioactive material in the environmental samples are performed as part of the Quality Assurance Program for environmental monitoring. To fulfill the requirement for an Interlaboratory Comparison Program, the JAF Environmental Laboratory has engaged the services of Eckert & Ziegler Analytics, Incorporated in Atlanta, Georgia.
Analytics supplies sample media as blind sample spikes, which contain certified levels of radioactivity unknown to the analysis laboratory. These samples are prepared and analyzed bythe JAF Environmental Laboratory using standard laboratory procedures.
Analytics issues a statistical summary report of the results. The JAF Environmental Laboratory uses predetermined acceptance criteria methodology for evaluating the laboratory's performance.
The JAF Environmental Laboratory also analyzes laboratory blanks. The analysis of laboratory blanks provides a means to detect and measure radioactive contamination of analytical samples. The analysis of analytical blanks also provides information on the adequacy of background subtraction. Laboratory blank results are analyzed using control charts.

The sample evaluation method is discussed below.
D.3.1 SAMPLE RESULTS EVALUATION Samples provided by Analytics are evaluated using what is specified as the NRC method. This method is based on the calculation of the ratio of results reported by the participating laboratory (0C result) to the Vendor Laboratory Known value (reference result).
D- 2
An Environmental Laboratory analytical result is evaluated using the following calculation:
The value for the error resolution is calculated.
The error resolution = Reference Result Reference Results Error (1 sigma)
Using the appropriate row under the Error Resolution column in Table 8.3.1 below, a corresponding Ratio of Agreement interval is given.
The value for the ratio is then calculated.
Ratio QC Result of Agreement Reference Result If the value falls within the agreement interval, the result is acceptable.

>200 0.85 to 1.18 This acceptance test is generally referred to as the "NRC" method. The acceptance criteria are contained in Procedure EN-CY-102. The NRC method generally results in an acceptance range of approximately +/- 25% of the Known value when applied to sample results from the Eckert & Ziegler Analytics Interlaboratory Comparison Program. This method is used as the procedurally required assessment method and requires the generation of a deviation from QA/QC program report when results are unacceptable.

- 1. Introduction GEL Laboratories, LLC (GEL) is a privately owned environmental laboratory dedicated to providing personalized client services of the highest quality. GEL was established as an analytical testing laboratory in 1981. Now a full servicelab, our analytical divisions use state of the art equipment and methods to provide a comprehensive array of organic, inorganic, and radiochemical analyses to meet the needs of our clients.
At GEL, quality is emphasized at every level of personnel throughout the company.
Management's ongoing commitment to good professional practice and to the quality of our testing services to our customers is demonstrated by their dedication of personnel and resources to develop, implement, assess, and improve our technical and management operations.
The purpose of GEL's quality assurance program is to establish policies, procedures, and processes to meet or exceed the expectations of our clients. To achieve this, all personnel that support these services to our clients are introduced to the program and policies during their initial orientation, and annually thereafter during company-wide training sessions.
GEL's primary goals are to ensure that all measurement data generated are scientifically and legally defensible, of known and acceptable quality per the data quality objectives (DQOs), and thoroughly documented to provide sound support for environmental decisions.
In addition, GEL continues to ensure compliance with all contractual requirements, environmental standards, and regulations established by local, state and federal authorities.
GEL administers the QA program in accordance with the Quality Assurance Plan, GL-QS-B-001. Our Quality Systems include all quality assurance (QA) policies and quality control (QC) procedures necessary to plan, implement, and assess the work we perform. GEL's QA Program establishes a quality management system (QMS) that governs all of the activities of our organization.
This report entails the quality assurance program for the proficiency testing and environmental monitoring aspects of GEL for 2010. GEL's QA Program is designed to monitor the quality of analytical processing associated with environmental, radiobioassay, effluent (10 CFR Part 50), and waste (10 CFR Part 61) sample analysis.
This report covers the category of Radiological Environmental Monitoring Program (REMP) and includes:
" Intra-laboratory QC results analyzed during 2010.
- Inter-laboratory QC results analyzed during 2010 where known values were available.
Laboratories LLC P.O. Box 30712, Charleston, SC 29417 2010 ANNUAL QUALITY ASSURANCE REPORT Page 6 of 51
- 2. Quality Assurance Programs for Inter-laboratory, Intra-laboratory and Third Party Cross-Check In addition to internal and client audits, our laboratory participates in annual performance evaluation studies conducted by independent providers. We routinely participate in the following types of performance audits:
- Proficiency testing and other inter-laboratory comparisons.
- Performance requirements necessary to retain Certifications
" Evaluation of recoveries of certified reference and in-house secondary reference materials using statistical process control data.
" Evaluation of relative percent difference between measurements through SPC data.
We also participate in a number of proficiency testing programs for federal and state agencies and as required by contracts. It is our policy that no proficiency evaluation samples be analyzed in any special manner. Our annual performance evaluation participation generally includes a combination of studies that support the following:
" US Environmental Protection Agency Discharge Monitoring Report, Quality Assurance Program (DMR-QA). Annual national program sponsored by EPA for laboratories engaged in the analysis of samples associated with the NPDES monitoring program. Participation is mandatory for all holders of NPDES permits.
The permit holder must analyze for all of the parameters listed on the discharge permit. Parameters include general chemistry, metals, BOD/COD, oil and grease, ammonia, nitrates, etc.
- Department of Energy Mixed Analyte Performance Evaluation Program (MAPEP). A semiannual program developed by DOE in support of DOE contractors performing waste analyses. Participation is required for all laboratories that perform environmental analytical measurements in support of environmental management activities. This program includes radioactive isotopes in water, soil, vegetation and air filters.
- ERA's MRAD-Multimedia Radiochemistry Proficiency test program. This program is for labs seeking certification for radionuclides in wastewater and solid waste. The program is conducted in strict compliance with USEPA National Standards for Water Proficiency study.
" ERA's InterLaB RadCheM Proficiency Testing Program for radiological analyses.
This program completes the process of replacing the USEPA EMSL-LV Nuclear Radiation Assessment Division program discontinued in 1998. Laboratories seeking certification for radionuclide analysis in drinking water also use the study. This program is conducted in strict compliance with the USEPA National Standards for Water Proficiency Testing Studies. This program encompasses Uranium by EPA method 200.8 (for drinking water certification in Florida/Primary NELAP), gamma
Laboratories LLC P.O. Box 30712, Charleston, SC 29417 2010 ANNUAL QUALITY ASSURANCE REPORT Page 7 of 51 emitters, Gross Alpha/Beta, Iodine-131, naturally occurring radioactive isotopes, Strontium-89/90, and Tritium.
" ERA's Water Pollution (WP) biannual program for waste methodologies includes parameters for both organic and inorganic analytes.
- ERA's Water Supply (WS) biannual program for drinking water methodologies includes parameters for organic and inorganic analytes.
- New York State Department of Health Environmental Laboratory Approval Program Proficiency Testing Program for Potable Water (PW)
- Environmental Cross-Check Program administered by Eckert & Ziegler Analytics, Inc. This program encompasses radionuclides in water, soil, milk, naturally occurring radioactive isotopes in soil and air filters.
GEL procures single-blind performance evaluation samples from Eckert & Ziegler Analytics to verify the analysis of sample matrices processed at GEL. Samples are received on a quarterly basis. GEL's Third-Party Cross-Check Program provides environmental matrices encountered in a typical nuclear utility REMP. The Third-Party Cross-Check Program is intended to meet or exceed the inter-laboratory comparison program requirements discussed in NRC Regulatory Guide 4.15, revision 1. Once performance evaluation samples have been prepared in accordance with the instructions provided by the PT provider, samples are managed and analyzed in the same manner as environmental samples from GEL's clients.
- 3. Quality Assurance Program for Internal and External Audits During each annual reporting period, at least one internal assessment is conducted in accordance with the pre-established schedule from Standard Operating Procedure for the Conduct of Quality Audits, GL-QS-EO01. The annual internal audit plan is reviewed for adequacy and includes the scheduled frequency and scope of quality control actions necessary to GEL's QA program. Internal audits are conducted at least annually in accordance with a schedule approved by the Quality Systems Director. Supplier audits are contingent upon the categorization of the supplier, and may or may not be conducted prior to the use of a supplier or subcontractor. Type I suppliers and subcontractors, regardless of how they were initially qualified, are re-evaluated at least once every three years.
In addition, prospective customers audit GEL during pre-contract audits. GEL hosts several external audits each year for both our clients and other programs. These programs include environmental monitoring, waste characterization, and radiobioassay. The following list of programs may audit GEL at least annually or up to every three years depending on the program.
- NELAC, National Environmental Laboratory Accreditation Program
- DOECAP, U.S. Department of Energy Consolidated Audit Program
- DOELAP, U.S. Department of Energy Laboratory Accreditation Program
- DOE QSAS, U.S. Department of Energy, Quality Systems for Analytical Services
- ISO/IEC 17025

The annual radiochemistry laboratory internal audit (10-RAD-001) was conducted in March 2010. Four findings, one observation, and two recommendations resulted from this assessment. Each finding was closed and appropriate laboratory staff addressed each observation and recommendation. The internal audit closed in June 2010.
- 4. Performance Evaluation Acceptance Criteria for Environmental Sample Analysis GEL utilized an acceptance protocol based upon two performance models. For those inter-laboratory programs that already have established performance criteria for bias (i.e.,
MAPEP, and ERA/ELAP), GEL will utilize the criteria for the specific program. For intra-laboratory or third party quality control programs that do not have a specific acceptance criteria (i.e. the Eckert-Ziegler Analytics Environmental Cross-check Program), results will be evaluated in accordance with GEL's internal acceptance criteria.
- 5. Performance Evaluation Samples Performance Evaluation (PE) results and internal quality control sample results are evaluated in accordance with GEL acceptance criteria. The first criterion concerns bias, which is defined as the deviation of any one result from the known value. The second criterion concerns precision, which deals with the ability of the measurement to be replicated by comparison of an individual result with the mean of all results for a given sample set.
At GEL, we also evaluate our analytical performance on a regular basis through statistical process control acceptance criteria. Where feasible, this criterion is applied to both measures of precision and accuracy and is specific to sample matrix. We establish environmental process control limits at least annually.
For Radiochemistry analysis, quality control evaluation is based on static limits rather than those that are statistically derived. Our current process control limits are maintained in GEL's AlphaLIMS. We also measure precision with matrix duplicates and/or matrix spike duplicates. The upper and lower control limits (UCL and LCL respectively) for precision are plus or minus three times the standard deviation from the mean of a series of relative percent differences. The static precision criteria for radiochemical analyses are 0 - 20%, for activity levels exceeding the contract required detection limit (CRDL).
- 6. Quality Control Program for Environmental Sample Analysis GEL's internal QA Program is designed to include QC functions such as instrumentation calibration checks (to insure proper instrument response), blank samples, instrumentation backgrounds, duplicates, as well as overall staff qualification analyses and statistical process controls. Both quality control and qualification analyses samples are used to be as similar as the matrix type of those samples submitted for analysis by the various laboratory clients. These performance test samples (or performance evaluation samples) are either
I Laboratories LLW P.O. Box 30712, Charleston, SC 29417 2010 ANNUAL QUALITY ASSURANCE REPORT Page 9 of 51 actual sample submitted in duplicate in order to evaluate the precision of laboratory measurements, or fortified blank samples, which have been given a known quantity of a radioisotope that is in the interest to GEL's clients.
Accuracy (or Bias) is measured through laboratory control samples and/or matrix spikes, as well as surrogates and internal standards. The UCLs and LCLs for accuracy are plus or minus three times the standard deviation from the mean of a series of recoveries. The static limit for radiochemical analyses is 75 - 125%. Specific instructions for out-of-control situations are provided in the applicable analytical SOP.
GEL's Laboratory Control Standard (LCS) is an aliquot of reagent water or other blank matrix to which known quantities of the method analytes are added in the laboratory. The LCS is analyzed exactly like a sample, and its purpose is to determine whether the methodology is in control, and whether the laboratory is capable of making accurate and precise measurements. Some methods may refer to these samples as Laboratory Fortified Blanks (LFB). The requirement for recovery is between 75 and 125% for radiological analyses excluding drinking water matrix.
Bias (%) = (observed concentration)
- 100 %
(known concentration)
Precision is a data quality indicator of the agreement between measurements of the same property, obtained under similar conditions, and how well they conform to themselves.
Precision is usually expressed as standard deviation, variance or range in either absolute or relative (percentage) terms.
GEL's laboratory duplicate (DUP or LCSD) is an aliquot of a sample taken from the same container and processed in the same manner under identical laboratory conditions. The aliquot is analyzed independently from the parent sample and the results are compared to measure precision and accuracy.
If a sample duplicate is analyzed, it will be reported as Relative Percent Difference (RPD).
The RPD must be 20 percent or less, if both samples are greater than 5 times the MDC. If both results are less than 5 times MDC, then the RPD must be equal to or less than 100%.
If one result is above the MDC and the other is below the MDC, then the RPD can be calculated using the MDC for the result of the one below the MDC. The RPD must be 100%
or less. In the situation where both results are above the MDC but one result is greater than 5 times the MDC and the other is less than 5 times the MDC, the RPD must be less than or equal to 20%. If both results are below MDC, then the limits on % RPD are not applicable.
Difference (%) = (high duplicate result - low duplicate result)
- 100 %
(average of results)
- 7. Summary of Data Results During 2010, forty-three radioisotopes associated with six matrix types were analyzed under GEL's Performance Evaluation program in participation with ERA, MAPEP, NYSDOH ELAP and Eckert & Ziegler Analytics. Matrix types were representative of client analyses performed during 2010. The list below contains the type of matrix evaluated by GEL.

- Vegetation Graphs are provided in Figures 1-8 of this report to allow for the evaluation of trends or biases. These graphs include radioisotopes Cobalt-60, Cesium-137, Tritium, Strontium-90, Gross Alpha, Gross Beta, and Iodine-131. A summary of GEL's quality control for radiological analyses by isotopic analysis and matrix are represented in Table 8. Each LCS and DUP represents a batch of samples for each isotopic analysis. This summary contains the number of reportable quality control results for our clients.
- 8. Summary of Participation in the Eckert & Ziegler Analytics Environmental Cross-Check Program During 2010, Eckert & Ziegler Analytics provided samples for 106 individual environmental analyses. Of the 106 analyses, 99% (105 out of 106) of all results fell within the PT provider's acceptance criteria. The only analytical failure occurred with the analysis of Iron-59 in milk. For the corrective action associated with the Iron-59 failure, refer to CARR1 10209-542 (Table 9).
- 9. Summary of Participation in the MAPEP Monitoring Program During 2010, one set of MAPEP samples (MAPEP 22) was analyzed by the laboratory. Of the 66 analyses, 80% (53 out of 66) of all results fell within the PT provider's acceptance criteria. Thirteen analytical failures occurred: Plutonium-238 in water, Uranium-235 in filter, Uranium-238 in filter, Uranium-Total in filter, Americium-241 in filter, Cesium-134 in filter, Cesium-137 in filter, Cobalt-60 in filter, Manganese-54 in filter, Plutonium-239/240 in filter, Uranium-244/243 in filter, Uranium-238 in filter, and Uranium-238 in vegetation.
For the corrective action associated MAPEP 22, refer to CARR100617-496 (Table 9). The ICP-MS analysis of Uranium-235 and Uranium-238 failure was attributed to the use of the less vigorous digestion method (EPA Method 3050B). After contacting RESL, GEL discovered that they had used a more rigorous total dissolution process. The failure for Plutonium-238 was attributed to a data reviewer's error and lack of attention to detail to the region of interest that was not included in the data result. Approximately 400 additional counts should have been included. For the remaining isotopic failures, the error was attributed to analyst error and failure to follow the instructions from the PT provider.
- 10. Summary of Participation in the ERA MRaD PT Program During 2010, the ERA MRad program provided samples (MRAD-12 and MRAD-13) for 175 individual environmental analyses. Of the 175 analyses, 96% (169 out of 176) of all results fell within the PT provider's acceptance criteria. Six analytical failures occurred: Uranium-234 in soil, Uranium-238 in soil, Uranium-238 in vegetation, Plutonium-238 in water, Uranium-238 in water, and Bismuth-212 in soil.
Laboratories LLC P.O. Box 30712, C hiareston, SC 29417 2010 ANNUAL QUALITY ASSURANCE REPORT Page 11 of 51 For the corrective actions associated with MRAD 12 and MRAD-13, refer to corrective actions CARR100617-497 and CARR101210-527, respectively (Table 9). For MRAD-12, the ICP-MS analysis of Uranium-235 and Uranium-238 failure was attributed to the use of the less vigorous digestion method (EPA Method 3050B). After contacting RESL, GEL discovered that they had used a more rigorous total dissolution process. For Uranium-238 in vegetation, air and water, the failure was attributed to method sensitivity by gamma spectroscopy. Future PT analysis will be performed using a more sensitive method.
For MRAD-13, the failure for Bismuth-212 was attributed to a reporting error. The actual result (1660 pCi/kg) was within the acceptance range. The failure of Iron-55 was attributed to matrix interference. An additional recount with a smaller aliquot and fresh reagent rinses removed the interferant.
- 11. Summary of Participation in the ERA PT Program During 2010, the ERA program provided samples (RAD-80 and RAD-82) for 53 individual environmental analyses. Of the 53 analyses, 77% (41 out of 53) of all results fell within the PT provider's acceptance criteria. Twelve analytical failures occurred: Strontium-89 in water, Strontium-90 in water, Barium-133 in water, Cesium-134 in water, Cesium-137 in water, Cobalt-60 in water, Zinc-65 in water, Uranium (Natural) in water, Uranium (Nat) Mass in water, Strontium-90 in water, Cesium-134 in water, and Zinc-65 in water.
For the corrective actions associated with RAD-80 and RAD-82, refer to corrective actions CARRIO0318-487 and CARR100907-512, respectively (Table 9). For RAD-80, the Gross Alpha failure was attributed to a concentrated iron carrier. The Strontium-89 and Strontium-90 failures were attributed to the associated weights of the carriers utilized during the preparation and analysis.
For RAD-82, failures of the Gamma Emitters and the Naturals (Uranium) were attributed to analyst error and failure to follow the instructions from the PT provider. The failure of Strontium-89 and Strontium-90 was attributed to analyst error while diluting the sample.
- 12. Summary of Participation in the New York ELAP PT Program During 2010, the NYSDOH ELAP PT program provided 30 individual tests for radiological analysis. Of the 30 analyses, 83% (25 out of 30) of the results were within the PT provider's acceptance criteria. Five analytical failures occurred: Cesium-134 in water, Iodine-1 31 in water (two), Strontium-89 in water, and Radium-226 in water.
For the corrective actions associated with NY-337, refer to corrective action CARR101203-525 (Table 9). For Cesium-134, Iodine-131, Strontium-89 and Strontium-90, and Radium-226, the failures could not be determined. The laboratory continues to monitor results of internal quality control samples.
In addition, GEL (Lab ID# E87156, Lab Code# SCO0012) maintained primary NELAP accreditation from the Florida Department of Health for the following methods in potable water and non-potable water. The radiological analytes and methods are listed below.

- 13. Quality Control Program for REMP Analyses GEL's internal (intra-laboratory) quality control program evaluated 1590 individual analyses for bias and 1591 analyses for precision for standard REMP matrix and radionuclides. Of the 959 internal quality control analyses evaluated for bias, 100% met laboratory acceptance criteria. In addition, 100% of the 1591 results for precision were found to be acceptable, The results are summarized in Table 8.
GEL performs low-level analysis specifically for Tritium in water. A chart of low activity H-3 spike performance is provided in Figure 8. All 2010 analyses were within the acceptance criteria.
- 14. Corrective Action Request and Report (CARR)
There are two categories of corrective action at GEL. One is corrective action implemented at the analytical and data review level in accordance with the analytical SOP. The other is formal corrective action documented by the Quality Systems Team in accordance with GL-QS-E-002. A formal corrective action is initiated when a nonconformance reoccurs or is so significant that permanent elimination or prevention of the problem is required.
GEL includes quality requirements in most analytical standard operating procedures to ensure that data are reported only if the quality control criteria are met or the quality control measures that did not meet the acceptance criteria are documented. A formal corrective action is implemented according to GL-QS-E-002 for Conducting Corrective/Preventive Action and Identifying Opportunities for Improvement. Recording and documentation is performed following guidelines stated in GL-QS-E-012 for Client NCR Database Operation.
Any employee at GEL can identify and report a nonconformance and request that corrective action be taken. Any GEL employee can participate on a corrective action team as requested by the QS team or Group Leaders. The steps for conducting corrective action are detailed in GL-QS-E-002. In the event that correctness or validity of the laboratory's test results in doubt, the laboratory will take corrective action. If investigations show that the results have been impacted, affected clients will be informed of the issue in writing within five (5) calendar days of the discovery.
Table 9 provides the status of CARRs for radiological performance testing during 2010.

INTRODUCTION In 2005, Entergy Nuclear Operations, Inc. (Entergy), the owner of the Indian Point Nuclear Power Plant located at Buchanan, NY on the Hudson River, discovered a spent fuel pool water leak to groundwater while installing a new crane to facilitate transfer of Unit 2 spent fuel to dry cask storage. This leak was determined to have generated a groundwater plume of tritium (3H).
During efforts to track the 3H plume, 90Sr was discovered in a downgradient portion of the plume and traced back to a leak in the Unit 1 spent fuel pool.
Because site groundwater flows to the Hudson River, the 2006 Radiological Environmental Monitoring Program (REMP) conducted by Entergy was modified to include 90Sr as an analyte in fish samples. 90Sr was detected in four of 10 samples of fish taken from the river in the vicinity of the power plant, and in three of five samples from an upstream reference location near the Roseton Generating Station in Newburgh, NY (Table 1). The tissues analyzed were composites of edible flesh from fish representing several species.
The data was reviewed by Entergy and compared with data for other facilities and historical information. Entergy concluded that the 90Sr levels were low and may be indistinguishable from background levels from fallout from nuclear weapons testing in the 1950s and 1960s (Entergy 2007). The New York State Departments of Health (NYSDOH) and Environmental Conservation (NYSDEC) (the Agencies) concurred. However, the Agencies were concerned that the home ranges of several sampled species, and all striped bass, may overlap at the two sampling sites. In order to assure independence of sampling sites, the Agencies initiated this one time enhanced radiological surveillance for 2007.
The objectives of the enhanced radiological monitoring effort were to:
- gain information about the levels, impacts, and possible 90Sr sources at the reference locations and the indicator station,
- determine if significant spatial differences in 90Sr concentrations were present,
- to assess whether or not 90Sr concentrations in the bones and flesh of fish signify heightened risk either to aquatic life in the Hudson River, and
- provide information for an independent assessment of potential public health impacts.
METHODS Part of Entergys REMP requirements is to conduct routine radiological surveillance using composite samples of edible tissues of fish two or more important commercial and/or recreational fish or invertebrate species. Possible target species include striped bass (Morone saxatilis), white perch (Morone americana), American eel (Anguilla rostrata), white catfish (Ictalurus catus) or channel catfish (Ictalurus punctatus), sunfishes including pumpkinseed (Lepomis gibbosus), bluegill (L. macrochirus) or redbreast sunfish (L. auritus), and blue crab (Callinectes sapidus). Sampling occurs in spring and fall of each year at two locations, i.e., in 2
the vicinity of Indian Point Nuclear Power Plant (approximately river mile 42) and the vicinity of Roseton Generating Station (the traditional reference station at approximate river mile 65). One composite sample of each species is collected at each location and is analyzed for a host of radionuclides.
Sampling is conducted by Normandeau Associates, Inc. under contract with Entergy, and samples consist of by-catch of fish or blue crabs taken as a consequence of sampling for other purposes. All samples were collected in June 2007 and were frozen (- 20º C) in a locked freezer until prepared for shipment for chemical analyses. The prepared sample mass is a minimum of 1600 g and a maximum of 2000 g. This sample mass is split three ways. The first split of 1000 g went to Entergys contract laboratory, AREVA, Inc. The second split of 300 to 500 g went to the Nuclear Regulatory Commission for analysis at the Oak Ridge Institute for Science and Education (ORISE). The third split (300 to 500 g) was sent to the NYSDOH Wadsworth Center for Labs and Research. Collection records and chain of custody are maintained for all samples (Appendix A).
The one-time design modifications for the 2007 effort included: the addition of carp (Cyprinus carpio) - a benthic feeder - to the target species list; adding 90Sr to the list of radionuclide analytes; analysis of fish bone or crab carapace; and sampling fish at a third location, i.e., the Catskill Region between river miles 107 and 125 (Figure 1). This upstream location assures appropriate separation of fish populations that are resident to the river, and, consequently, assures isolation of resident fish populations from the potential influence of the Indian Point Nuclear Power Plant.
Normandeau Associates, Inc. prepared the samples of edible portions of fish and blue crabs.
Skinless filets were excised from each specimen, composites by species were made, and each composite was thoroughly ground and homogenized. Subsamples were developed for each laboratory. These were double packaged in food grade plastic bags, labeled, frozen, and shipped to each participating laboratory.
The remaining carcasses of the fish and blue crabs were provided to the NYSDECs laboratory at the Hale Creek Field Station, Gloversville, NY where they were prepared for radiological analyses by the NYSDOH Wadsworth Center for Labs and Research. In addition to the required species, samples of other fish species were provided to Hale Creek including yellow perch (Perca flavescens), rock bass (Ambloplites rupestris), smallmouth bass (Micropterus dolomieui),
largemouth bass (Micropterus salmoides), black crappie (Pomoxis nigromaculatus), and brown bullhead (Ameiurus nebulosus).
Preparation of bone and carapace samples was conducted in several steps. First, the samples were cleaned to remove as much muscle, skin, scales or other tissues as possible. The resulting bone samples were placed in a fume hood and air dried for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, then each sample was individually bagged, labeled and stored in a locked freezer until they were sent for further cleaning by dermestid beetles maintained by the New York State Museum at their Rensselaer Technology Park offices in Troy, NY. Each bone sample was maintained in an individual labeled sample container while undergoing dermestid cleaning. Following this process, each sample was frozen to kill the dermestids, rethawed, and the frass (dermestid larval carcasses and 3
fecal material) was removed from the bone. Finally, the skeletal and cranial bones (fins were excluded) were placed in food grade plastic bags, labeled and submitted to the NYSDOH Wadsworth Center for Labs and Research. Continuing chain of custody was maintained throughout the process (Appendix B).
Analysis of radionuclides were conducted by NYSDOH using two methods:
- 90 Sr analyses of fish bone were conducted by USEPA Method 905.0 (Krieger and Whittaker 1980b). Steps in this method include isolation of strontium, measurement of total strontium, hold the strontium for decay to allow time for the ingrowth of the yttrium-90 daughter, isolate and measure yttrium-90.
- Common indicator radionuclides (134Cs, 137Cs, 60Co, and 40K) were analyzed using USEPA Method 901.1 (Krieger and Whittaker 1980a).
Concentrations reported in Tables are the value for the sample +/- the analytical standard error.
For example, a value of 8 +/- 2 pCi/kg would mean the best estimate concentration is 8 pCi/kg although the concentration may be as little as 6 pCi/kg or as much as 10 pCi/kg.
Statistical tests for spatial differences in concentrations employed the Kruskal-Wallis test when there were three comparisons. The Mann-Whitney test was used when there were only two comparisons (Conover 1980). These non-parametric tests were chosen because of their ability to reduce the influence of outlier data. A difference was considered significant when the probability was less than 0.05 (P < 0.05).
RESULTS Edible Tissue Samples 90 Sr was detected in only one sample of edible tissues, i.e., 8 +/- 3 pCi/kg in blue crab taken from the vicinity of the Indian Point facility. Detection limits ranged between 3 and 6 pCi/kg (Table 2). Only the determinations made by the NYSDOH Wadsworth Center for Labs and Research are reported since their analytical methods were the most sensitive of the three laboratories conducting the analyses. No detectable radionuclides were reported by the other two laboratories.
Bone and Carapace Samples 90 Sr concentrations in bone of fish or the carapace of blue crabs are shown in Table 3. 90Sr concentrations are relatively consistent among all fish species, including striped bass, within locations. Mean and standard deviation concentrations for all fish at the three locations were:
4
90 Location n Sr Concentration (pCi/kg)
Indian Point 10 199 +/- 58 Roseton 10 222 +/- 67 Catskill 10 271 +/- 69 The single blue crab sample, taken from the Roseton area, had 760 pCi/kg of 90Sr in the carapace. This is the highest 90Sr concentration reported, and twice the highest fish concentration of 360 pCi/kg in yellow perch from the Catskill area.
Among other radionuclides analyzed, 134Cs, 137Cs, 58Co and 60Co were not detected in bone or carapace of any sample. Detection limits ranged from 0.2 to 80 pCi/kg for 134Cs, 137Cs and 60Co, and an order of magnitude greater for 58Co. 40K was present in nearly all samples within a limited range of concentrations and with mean and standard concentrations by area in fish as follows:
40 Location n K Concentration (pCi/kg)
Indian Point 9 2840 +/- 678 Roseton 10 3540 +/- 978 Catskill 10 2740 +/- 614 Table 4 presents concentrations of other radionuclides that were detected in bones of fish.
DISCUSSION 90 Sr in bone versus edible tissues Whicker et al. (1990) compared 90Sr concentrations in bone and edible flesh of fish taken from a cooling water pond at the USDOE Savannah River nuclear power plant. Similar comparisons were made for fish in waters downstream of the Nuclear Fuels Services Inc. nuclear waste treatment plant in West Valley, NY, and in Lake Ontario (NYSDEC 1971) (Table 5). In these studies the ratio of 90Sr in bone to that in edible fish tissue (90Sr bone:flesh ratio) ranged from less than one to 1198. The highest value is considered an outlier. The mean 90Sr bone:flesh ratio, excluding the outlier, was about 35. (The mean must be viewed with caution since the West Valley study did not indicate whether the 90Sr quantification method was the same as that used in the Savannah River study; wet weight versus dry mass in flesh, or original mass versus ash weight of bone. If the methods used are not the same the ratios may not be comparable.) If it is assumed that the two studies are comparable, and we apply this ratio to bone in the present study, the 90Sr concentration in edible tissues would very near or below the detection limit. This tends to confirm the reported lack of detection of 90Sr in edible flesh of fish from the lower Hudson River (Tables 2 and 5) in 2007.
5
Spatial differences There were no significant differences (P = 0.096) in 90Sr concentrations between the three locations for resident fish. Looking at reference stations only, there was no significant difference in 90Sr at Catskill and Roseton. Inclusion of striped bass, a migratory fish species, would not have changed the overall conclusion because of the similarity of 90Sr concentrations.
In contrast, 40K was statistically greater (P = 0.018) at the Roseton station than at either Indian Point or Catskill (which were equivalent) despite the small difference in average 40K concentrations. Inclusion of striped bass would not have changed the finding. 40K is a naturally occurring primordial radionuclide (Copplestone et al. 2001) which is expected to be found at these concentrations in fish and is not associated with nuclear waste for power production or fallout from weapons testing (Eisler 1994). The differing levels, albeit they are small differences, have no known significance.
Lastly, there were no differences between stations for 224Ra. There were insufficient data to assess spatial differences for other radionuclides.
Relationship to criteria The U.S. Department of Energy (USDOE) developed ecological standards for the protection of terrestrial animals, terrestrial plants, and aquatic animals based on published literature reviews of the effects of ionizing radiation on biota (NCRP 1991; IAEA 1992; UNSCEAR 1996). The standard for the protection of aquatic animals is:
The absorbed dose to aquatic animals should not exceed 1 rad/day (10 mGy/day or 400 µGy/hr1) from exposure to radiation or radioactive material releases into the aquatic environment.
This dose is specified in DOE Order 5400.5 (USDOE 2002). This standard is designed to protect populations of aquatic organisms, not individuals. At absorbed dose rates below the standard, populations will be maintained but some individual animals can suffer adverse impacts.
USDOE (2002) provides dose conversion factors (DCF) which can be used to estimate the absorbed dose from the internal abundance/activity of a radionuclide accumulated by an aquatic organism. The DCF calculations are conservative in that they assume all of the energies of radioactive decay are retained in the tissue of the organism, and that the radionuclides were presumed to be homogenously distributed in tissue. They are expressed in units of Rad/day per pCi/g wet weight. Using the DCFs it is possible to estimate the absorbed dose from the internal radionuclide concentration. Additional conversions were employed to express the total dose in 1
A Gray (Gy) is a standard international unit of absorbed dose of radiation adopted by the International Commission on Radiological Protection in 1977. 1 Rad = 0.01 Gy; conversely, 1 Gy = 100 Rads.
6
the Standard International (SI) units for chronic absorbed dose rates of µGy/hr. USDOE (2002) did not report DCFs for 224Ra and 40K.
The highest tissue/bone concentrations of radionuclides listed in Tables 1 - 4 are the upper bound concentrations (i.e., measured concentration plus the 95% confidence interval) of 809 pCi/kg of 90Sr from blue crab carapace (Table 3), 370 pCi/kg of 238U and 320 pCi/kg 232Th measured in the bones of striped bass (Table 4). All three samples were collected from the Roseton Generating Station (River Mile 65). Using the DCFs from (USDOE 2002), these concentrations can be converted to an internal dose rates:
809 pCi/kg of 90Sr would result in an estimated internal dose rate of 0.02 µGy/hr; 370 pCi/kg of 238U would result in an estimated internal dose rate of 0.7 µGy/hr; and 320 pCi/kg of 232Th would result in an estimated internal dose rate of 5.5 µGy/hr.
All of these dose rates range from about two to five orders of magnitude below the USDOE (2002) standard of protection for aquatic animals. While the highest internal dose to striped bass from a single radionuclide was from 232Th. However, to estimate the total internal dose, the internal doses from all radionuclides present must be summed. Using the upper bound concentrations for 226Ra, 232Th, and 238U with the DCFs from (USDOE 2002), the total internal dose to striped bass collected at the Roseton Power Generating Station can be estimated to be 8.4
µGy/hr. A DCF for 224Ra is not available, probably because this is a short-lived radionuclide with a half-life of only 3.7 days (Eisler 1994). 224Ra disintegrates rapidly through a series of seven daughter radionuclides to the stable nuclide 208Pb with a total half-life for the whole series of about 65 minutes (Nebergall et al. 1968).
The standards of protection published in USDOE (2002) were derived from a qualitative evaluation of radiological effects data. The European Union (EU) took a more quantitative approach to deriving ecological standards. EU assembled a large database of the impacts of ionizing radiation to biota and evaluated the studies to identify critical toxicity endpoints. Once the critical toxicity endpoints were determined, they were used with standard EU risk assessment protocols to derive a chronic Predicted-No-Effect-Dose Rates (PNEDR) screening value of 10
µGy/hr for freshwater, terrestrial, and marine/estuarine ecosystems (Garnier-Laplace and Gilbin 2006). The total absorbed dose from the internal concentration of 232Th, 226Ra, and 238U in striped bass is less than the chronic screening no effects dose rate derived by the EU.
The internal dose rate conversion factors from USDOE (2002) are conservative, but they do not take into account absorbed doses received from external sources, such as radionuclides in the water and sediment. There is no way to estimate those dose rates without measurements.
USDOE (2002) provides a method for estimating the total absorbed dose to biota from both external and internal sources. This approach uses Biota Concentration Guides (BCG)s which are concentrations of 23 different radionuclides in water, soil, and sediment. If the BCG concentrations are not exceeded, the total absorbed dose will not exceed the USDOE (2002) standards of protection. In order to utilize this method, simultaneous samples of water and sediment must be collected and analyzed in the immediate vicinity of suspected unregulated releases of radioactive materials into the Hudson River.
7
No excursions above ecological standards for the protection of aquatic animals appear to have occurred. However, the current monitoring effort does not allow for the full assessment of risks to aquatic animals. To fully evaluate the risks, the concentrations of the full range of 23 radionuclides listed in USDOE (2002) in both water and sediment samples collected from the same location simultaneously should be sampled. This would allow for the full use of the Graded Approach for Evaluating Radiation Doses to Aquatic and Terrestrial Biota as described in USDOE (2002) to be employed to evaluate and assess risks to aquatic biota.
The 23 radionuclides which should be sampled include: 241Am, 144Ce, 135Cs, 137Cs, 60Co, 154Eu, 155 Eu, 3H, 129I, 131I, 239Pu, 226Ra, 228Ra, 125Sb, 90Sr, 99Tc, 232Th, 233U, 234U, 235U, 238U, 65Zn, and 95 Zr.
CONCLUSIONS Two conclusions can be made.
- 1. There are no apparent excursions above criteria for the protection of biota based on the radionuclide data available. The levels of radionuclides - including 90Sr - were two to five orders of magnitude lower than criteria established for protection of freshwater ecosystems.
- 2. There were no spatial differences in concentrations of 90Sr and 224Ra in resident fish from the three locations sampled in the lower Hudson River (i.e., Indian Point Nuclear Power Plant, and the reference sites at the Roseton Generating Station and at Catskill). In contrast, 40K levels were somewhat greater in the vicinity of Roseton Generating Station, but the differing concentrations have no known significance.
ACKNOWLEDGMENTS The authors gratefully acknowledge the assistance and cooperation of a number of people during the conduct of this study. These include: Michael Ritchie and his staff at Normandeau Associates Inc. who provided the carcasses of fish and blue crabs used in this study; Anthony Gudlewski, Brian Buanno and John Finn at the NYSDECs Hale Creek Field Station who conducted the initial cleaning and drying of carcass samples; and Joseph Bopp of the NYS Museum who maintained and oversaw use of the dermestid beetle colony. Helpful comments on manuscript were provided by Larry Rosenman (NYSDEC), Anthony Forti, Edward Horn, Robert Snyder and Stephen Gavitt (NYSDOH), and Kathleen Skinner (Russell Sage College).
