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 hours, 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 Gy/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 Gy/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 Gy/hr; 370 pCi/kg of 238U would result in an estimated internal dose rate of 0.7 Gy/hr; and 320 pCi/kg of 232Th would result in an estimated internal dose rate of 5.5 Gy/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 Gy/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 Gy/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.
