NEW YORK STATE DEPARTMENT OF HEALTH Environmental Radiation in New York State 1994 ANNUAL REPORT

EXECUTIVE

SUMMARY

This 1994 report is a continuation of the series of annual reports on Environmental Radiation in New York State prepared by the Department of Health (DOH) since 1982 and previously prepared by the Department of Environmental Conservation (DEC).

The environmental radiation surveillance program measures the level of radionuclides in environmental media to determine the normal levels of background radioactivity in several locations in the state and monitors the influence of human activities on these levels. Monitoring was performed around three operating nuclear power plant sites, several other reactors and industrial facilities which also use radioactive materials. The worldwide distribution of radionuclides from atmospheric nuclear weapons tests and the use of radioactive materials in energy generation, industry and medicine comprise the components of the man-made radiation environment.

Levels of fission products from previous atmospheric weapons testing continue to show a slow decrease with time.

Detectable low levels of radionuclides above normal background levels were measured in the environment near a number of facilities. The data did not indicate the facilities were exceeding limits for discharge to the environment as specified in the New York State Sanitary Code (10 NYCRR Part 16), or the appropriate Department of Environmental Conservation Regulations (6 NYCRR Part 380).

1. INTRODUCTION The New York State Department of Health (DOH) measures the levels of radiation exposure and radioactive materials at locations subject to potential releases from certain facilities.

Measurements and samples are collected from other sites that serve as background for the measurements around the nuclear facilities. These measurements provide an indication of environmental levels in the sampling locations. This program is not intended to provide a complete mapping of environmental radiation levels in the state.

Data collected often show results to be less than the level of detection. While these results provide an indication of a source's compliance with the regulations, they are not useful in determining the actual low-level human exposure to man-made radiation.

The National Council on Radiation Protection and Measurements (NCRP) estimates that the average U.S. resident is exposed to 360 millirems per year from all radiation sources (NCRP Report 93 Ionizing Radiation Exposure of the Population of the United States - 1987).

Radiation from natural sources in the environment contributes about 82 percent of this dose.

This includes radiation from the earth, cosmic rays from space, atmospheric radioactivity, radioactive elements within our bodies and within the foods and water that we consume.

Indoor radon accounts for about 55 percent of the total (200 mrem/year). Human use of radiation, primarily medical use, contributes the remaining 18 percent of the annual estimated dose. Unnecessary exposure to radiation from man-made sources and radioactive materials releases to the environment should be as low as reasonably achievable.

1.1 Types of Samples Collected Various types of samples were collected to measure the distribution of radionuclides in the environment. Types of samples taken include air, water, milk, sediment, food, animals and fish, although not all are collected at each site. At some sites, thermoluminiscent dosimeters (TLD) are also used to measure the direct environmental gamma radiation level.

The samples were not meant to directly monitor releases from the discharge points at specific facilities (e.g., a stack). The facility operator normally conducts such monitoring to meet requirements of the licensing agency. The environmental samples are intended to assess the impact at nearby locations and to evaluate trends over time.

1.2 Sample Collection and Analysis DOH personnel, local health units and, in some cases, the site operator collect samples. The New York State Department of Health's Wadsworth Center (WC) then analyzes these samples using a variety of equipment and appropriate methods for the 1

specific sample type and radionuclides of interest. For some samples, the analysis follows radiochemistry procedures which extract and concentrate the radionuclides of interest. A brief description of how samples are collected and analyzed is given below.

1.2.1 Air Continuous air samplers are used to draw approximately one cubic foot of air per minute through the sampling media described below. Samplers normally run one to two weeks to allow a sufficient air volume to pass through the sampling medium.

1.2.1.1 Particulate Filters Paper filters are used to measure the activity of particulates in the air.

-Gross beta activity is measured as a screening procedure. Composite samples are also analyzed using gamma spectroscopy.

1.2.1.2 Activated Charcoal Cartridges '

The Department uses activated charcoal to collect the various radioisotopes of iodine. Analysis is by gamma spectroscopy or radio chemical separation of 1-131 for beta/gamma coincidence counting.

Chemical extraction of 1-129 and 1-125 precedes analysis using an intrinsic-germanium detector. The WC uses this method for samples taken near the Cintichem facility.

1.2.1.3 Silica Gel Columns Airborne tritium (H-3 as tritiated water vapor HTO) is measured by passing air through a silica gel column. The H-3 activity of the absorbed water is measured using liquid scintillation counting.

1.2.2 Milk Two liter samples of milk are collected near facilities which may release fission products such as 1-131, Cs-137 or Sr-90. Analysis may include gamma spectroscopy, and specific measurements for beta emitters such as Sr-90 and tritium. Radiochemistry methods may also be used in the analysis for radionuclides such as Sr-90 or radioiodines.

2

1.2.3 Water Samples are two liters in volume and are collected as grab samples or aliquots of continuous samples. Composite samples are made by mixing equal portions of several samples together to measure the average values over a longer time span. Samples are analyzed for gross alpha, gross beta, isotopic gamma (several radionuclides), Sr-90 or tritium activity (as tritiated water HTO). When gross alpha activity exceeds 15 pCi/Liter (pCi/L) or gross beta activity exceeds 50 pCi/L, gamma spectral analysis is performed to identify the particular radionuclides present in the sample.

1.2.4 Fallout Fallout samples are collected in buckets which are exposed to atmospheric precipitation and dust. These samples are analyzed for Sr-89 and Sr-90 activity at the Albany location and for HTO at Elmsford, Westchester County.

1.2.5 Soil and Sediment Soil or sediment samples are collected from areas where the long-term deposition of radionuclides in soil or sediment is of interest. Analysis is usually by means of gamma spectroscopy.

1.2.6 Food or Vegetation Samples of local food or vegetation are collected near sites of interest to monitor radionuclide concentrations in edible material. Analysis is usually by gamma spectroscopy.

1.2.7 Animals and Fish Biological samples are used to monitor radionuclide concentrations in fish and/or animals (usually deer) near sites of interest. For deer samples, radionuclide concentrations of various fuel-cycle products, tritium, Cs-137, Sr-90, Pu-239 and 1-129 are measured in flesh, thyroid and lung tissue. Fish samples are analyzed as whole fish (meat plus bones with head, tail and fins removed) or may be separated into flesh and bone components which are then analyzed individually for fission products of interest and natural radioactivity.

3

1.2.8, Direct Environmental Radiation Direct environmental radiation monitoring around nuclear facilities is done using thermoluminiscent dosimeters (TLDs) which provide a quantitative measurement of the radiation levels in the area in which they are placed.

TLDs are normally exposed for periods of 3 months.

1.3 Types of Sampling Sites Sampling sites are generally of three types, i.e., background, routine nuclear and nonroutine sites.

1.311 Background Locations These are sites which should not be affected by the operation of facilities that

.. 'release radionuclides to the environment. Samples taken at these locations should show normal concentrations of naturally occurring radionuclides plus any influences from weapons testing fallout and the buildup of radioactivity from the global use of nuclear energy.

1.3.2 Routine Nuclear Sites

'These sites are used to measure the influence of -specific facilities on radioactivity in the environment. A paired site may be chosen as a background location for the site of interest, e.g., a sampling site upstream from a facility's point of release to the stream may serve for a "background" sampling location.

1.3.3 Non-routine Sites These locations are used for a specific purpose, and their inclusion in later reports will depend on circumstances associated with the particular location.

1.4 Reporting of Sample Analysis Results Sample results are reported in one of three ways. The following is an example for Sr-90:

Nuclide Concentration (1pCi/L)

Sr-90 20 +/- 5 Sr-90 <8 Sr-90 Not Reportable or No Sample 4

In the first example, a concentration value is given with the associated two standard deviation uncertainty limit. The limit implies that the actual value has a 95 percent probability'of being within the interval 15 to 25 pCi/L.

In the second example, the concentration is reported as less than the minimum detectable level of 8 pCi/L. This level depends on several factors, some of which include sample quantity and type, instrument sensitivity, background activity and counting time. Typical minimum detectable levels for various radionuclides and sample types are given in Attachment A. The annual average effluent concentrations for air and water releases to unrestricted areas listed in the New York State Sanitary Code, Part 16 are given in Attachment B. These are the concentrations contained in the Regulations which were revised in 1994. They differ from the maximum permissible concentrations that applied prior to 1994, and were listed in the previous Annual Environmental Radiation reports. These values are equivalent to the radionuclide concentrations which, if inhaled or ingested continuously over the course of a year, would result in a total effective dose equivalent of 50 mrem (0.5 mSv). The same concentrations are also tabulated in the Department of Labor, Industrial Code Rule 38, the Department of Environmental Conservation Part 380, New York City Health Code, Article 175, and correspond to the values shown in the Code of Federal Regulations, 10 CFR Part 20.

In the third example, the sample could not be analyzed for some reason such as when the sample is damaged, lost or when correct sample information is not available or no sample was collected during the period.

2. RESULTS 2.1 Background Sites Background samples are collected from several sites statewide which are not expected to be influenced by discharges of radionuclides to the environment. These locations establish the normal levels of radionuclides in the environment. This includes natural sources and atmospheric fallout from nuclear weapons testing.

Figure 2.1-1 shows the location of the background and major nuclear facilities sites.

Table 2.1.1 gives the sample type and collection frequency. Data for these locations are included in this report. This allows comparison to other locations of interest.

The water samples collected in Albany County are from the City of Albany public water supply system taken from the tap at the Wadsworth Center Laboratories, Empire State Plaza, Albany, New York. Similarly, the Albany milk samples are from processed milk sold in Albany, New York. Air and fallout samples in Albany are collected at the roof of the Albany County Health Department in Albany, New York.

2.1.1 Radioactivity in Air Analyses of air samples taken in Albany show that gross beta activity in air was within the typical range for background levels, typically from 0.005 to 0.02 pCi/m3 . The naturally occurring radionuclide Be-7 is measurable in quarterly composite samples. Weekly and quarterly air sample results are presented in Tables 2.1.2 and 2.1.3, respectively.

2.1.2 Radioactivity in Milk Results for weekly milk samples collected from the cafeteria at the ESP show that K-40 contributes most of the radioactivity in the samples, typically in the range 1,200 to 2,100 pCi/L. This year low levels of the fallout radionuclide Sr-90 were measured. The Cs-137 values have been below the minimum detectable levels since 1972. In 1994, the measured levels of Sr-90 were below 2.1 pCi/L and the monthly average was 1.55 pCi/L. Figure 2.1-2 shows the annual average levels of Cs-137 and Sr-90 for 1963 through 1994.

Values for the radioiodines (1-125, 1-129, 1-131) are all below minimum detection levels. Weekly, monthly and quarterly milk sample results are given in Table 2.1.4 6

2.1.3 Radioactivity in Water Background water samples include raw samples taken from lakes and rivers, as well as drinking water samples taken from the tap at the DOH's laboratories. The analyses of these samples show typical levels of radionuclides for drinking water or environmental samples. Gross alpha levels are typically below detection limits and gross beta levels are typically below 4 pCi/L. Tritium (HTO) is typically below 200 pCi/L. Fallout fission products were near or below minimum detectable levels. Weekly and monthly water sample results are given in Tables 2.1.5 to 2.1.8.

2.1.4 Radioactivity in Fallout Fallout samples are collected in buckets which are exposed to atmospheric precipitation and dust at the Albany County Health Department background site. These samples are analyzed for Sr-89, Sr-90, isotopic gamma and tritium. Weekly and monthly composite fallout results are given in Table 2.1.9. Except for Be-7 and H-3 insome of the samples, all measurements show concentrations that are below the minimum detectable levels.

2.1.5 Direct Environmental Radiation TLDs were placed at Voorheesville, Albany County, at a DOH employee's home as a background station. There are no nuclear facilities around the area, therefore the results are used for background measurement. Results are presented in Table 2.1.10.

2.2 Routine Nuclear Sites 2.2.1 BROOKHAVEN NATIONAL LABORATORY (BNL), UPTON, SUFFOLK COUNTY This facility is operated by the U.S. Department of Energy. There are two research reactors on the site, the 60 megawatt thermal (MWt) High Flux Beam Reactor (HFBR) and the 5 MWt Medical Research Reactor (MRR). Other nuclear facilities include the Brookhaven Linac Isotope Production Facility, hot cells and storage areas for spent reactor fuel. Figure 2.2-1 shows the facility and some nearby sampling sites. Table 2.2.1 shows information on sample type and collection frequency.

2.2.1.1 Radioactivity in Air The Department of Health air sampler is located at one of the BNL air monitoring sites. Sampling at this location was stopped on March 24, 1993 due to building construction activities by BNL at this site. Results of gross beta activity in air were within the typical range for background levels of less than 0.02 pCi/m 3 . Air sampling was resumed on September 9, 1994 when the building repair was completed. However, it was discovered that air flow to the sample holder resulted in invalid measurements. Therefore, air measurement results are reported only for the last quarter in 1994.

2.2.1.2 Radioactivity in Milk There are no dairy farms operating on Long Island. Therefore, no milk samples were available in 1994.

2.2.1.3 Radioactivity in Water Monthly samples were collected from the Peconic River where it leaves the BNL site. Effluents from the BNL Sewage Treatment Plant are discharged to the Peconic River. Gross alpha and gross beta results were typical of background levels. Measurable levels of tritium (HTO) were found to range between 320 to 4,100 pCi/L. The most likely source of the tritium is movement of contaminated groundwater and surface runoff from the site.

The tritium levels found were below the EPA drinking water standard of 20,000 pCi/L. The minimal average tritium concentrations from 1973 to 1994 in the Peconic River are shown on Figure 2.2-2. Results of quarterly water samples are given in Table 2.2.3.

24

2.2.1.4 Radioactivity in Fish and Shellfish Except for 1977 and 1979, fish samples have been collected each year since 1973 from waters along the Peconic River. These include samples collected from Donahue's and Forge Ponds, Peconic Lake and Peconic River. Control samples have been collected from Swan Pond routinely and occasionally from other ponds, including Preston and Sandy Ponds and Lower Lake.

These samples are normally collected by the DEC staff and analyzed by DOH's WC laboratories. This year samples collected include mussels and fish. The K-40, Sr-90 and Cs-137 concentrations measured in the samples are given in Table 2.2.4.

2.2.2. CINTICHEM (FORMERLY UNION CARBIDE), TUXEDO, ORANGE COUNTY This'facility, located in the Sterling Forest Industrial Park, contains a 5 MWt research reactor that once produced radioactive pharmaceuticals for use in medicine. Figure 2.2-3 shows the location of the site and some of the nearby sampling points including the location of the TLD monitors used to measure the external background radiation level. Table 2.2.5 provides information on the sampling sites.

In 1990 Cintichem shut down the reactor following the discovery of contamination outside the reactor building. The reactor and radioisotope processing hot cells were decommissioned in 1994.

2.2.2.1 Radioactivity in Air Air samples showed low levels of gross beta activity, while 1-125, 1-129 and 1-131 were below minimum detection level. Results of weekly and composite air samples are presented in Tables 2.2.6 and 2.2.7, respectively.

2.2.2.2 Radioactivity in Milk Due to the fact that the nearby farmer who previously supplied milk samples went out of business and Cintichem was being decommissioned, no milk samples were collected in 1994. The last milk sample was collected in October 1992.

2.2.2.3 Radioactivity in Water Water samples were collected at two locations, at Indian Kill and at the Sterling Forest Water Treatment Plant. The former showed HTO concentrations, which ranged from less than detectable levels to 1,800 pCiiL.

All the gross alpha results were below the detection limit except for the sample collected August 12, where the gross alpha result was 19+11 pCi/L.

Gross alpha measurement results for the latter ranged from below minimum detection level to 2.1+/-1.8 pCi/L. The concentration ranged from below detection level to 10 pCi/L for gross beta. Results from weekly samples are given in Tables 2.2.8 and 2.2.9.

2.2.2.4 Direct Environmental Radiation Data for the quarterly values for the TLD sites were typical of the normal background level in this area. Results are presented in Table 2.2.10.

2.2.3 GINNA NUCLEAR POWER STATION, ONTARIO, WAYNE COUNTY Rochester Gas & Electric operates the R.E. Ginna nuclear power plant located on the shore of Lake Ontario. This facility houses a 420 Megawatt electric (MWe) pressurized-water reactor that uses cooling water from Lake Ontario.

Figure 2.2-4 shows the site location and some nearby sampling points. Table 2.2.11 gives a description of the sampling sites.

2.2.3.1 Radioactivity in Air Results for gross beta activity were within the normal range for background levels and 1-131 levels were below the minimum detectable level. Weekly and quarterly results are presented in Tables 2.2.12 and 2.2.13, respectively.

2.2.3.2 Radioactivity in Milk Results for monthly milk samples collected from nearby farms showed that naturally occurring K-40 contributes most of the radioactivity in the samples.

Typically, low levels of Sr-90 and HTO were measurable while Cs- 137 and 1-131 were below minimum detection levels. The tritium levels in milk are higher than those reported in previous years. Release data from the utilities do not indicate higher releases to the environment. For a period during the last quarter the laboratory made a procedural change in how the milk samples were analyzed for tritium which may have resulted in reporting higher concentrations than the true values. Monthly results from two farms are presented in Tables 2.2.14 and 2.2.15, respectively.

2.2.3.3 Radioactivity in Water Biweekly water samples were collected using a continuous water sampler at the Town of Ontario water filtration plant which takes its water from Lake Ontario. The gross alpha and gross beta activities were typical of background values.

Weekly results are presented in Tables 2.2.16 and monthly composite results are presented in Table 2.2.17. Monthly samples from the discharge canal (Site #5857-005) showed undetectable levels of Zr-95, Ru-106 and Cs-137.

Measurable levels of tritium were found to range between 200 and 400 pCi/L.

42

These measured values are below the EPA drinking water standard of 20,000 pCi/L, and are consistent with other background samples around the state.

Results from the discharge canal and Russel station samples are given in Tables 2.2.18 and 2.2.19, respectively.

2.2.3.4 Radioactivity in Sediment Table 2.2.20 shows the results of sediment samples from the Ginna plant, K-40 was responsible for most of the activity. Trace amounts of Cs-137were detected in the sample.

2.2.3.5 Radioactivity in Vegetation Vegetable samples were collected at the Ginna area. The results indicate background levels of activity and they are presented in Table 2.2.21.

2.2.3.6 Radioactivity in Fish Fish samples show that naturally occurring K-40 is responsible for most of the activity. Trace amounts of Cs-137 were detected in the sample. Results of the sample are presented in Table 2.2.22.

2.2.3.7 Direct Environmental Radiation Values measured by the TLD monitors were typical of the normal background radiation levels for these locations, and are shown in Table 2.2.23.

Figure 2.2-4. Ginna Nuclear Power Reactor Sampling Locations.

2.2.4 INDIAN POINT SITES, BUCHANAN, WESTCHESTER COUNTY The Indian Point Site is located on the Hudson River shore near PeekskilL Two electric utilities have operating nuclear power plants at this site.

Consolidated Edison (ConEd) operates Unit 2 which houses an 873 MWe, pressurized-water reactor. The initial reactor (Unit 1) at the site, also owned by Con ED, is awaiting decommissioning and is not operational. The New York Power Authority (NYPA) operates Unit 3, which is a 965 MWe, pressurized-water reactor..

Both operating reactors obtain cooling water from the Hudson River.

Figure 2.2-5 shows the location of the site and some sampling locations in the vicinity. Table 2.2.24 gives a description of the sampling sites.

2.2.4.1 Radioactivity in Air Air samples showed low levels of gross beta activity and levels of 1-131 were below detection levels. Weekly and quarterly results are given in Tables 2.2.25 and 2.2.26, respectively.

2.2.4.2 Radioactivity in Milk The last commercial dairy farm operating near this site went out of business in 1992. Therefore, no milk samples were collected in 1994.

2.2.4.3 Radioactivity in Water Water samples showed low levels of gross beta activity. Tritium levels were at typical background levels. The levels for other radioisotopes were low with most samples below minimum detectable levels. Results are presented in Tables 2.2.27 to 2.2.30.

2.2.4.4 Radioactivity in Fish Fish samples show that naturally occurring K-40 is responsible for most of the activity. All other isotopes are below detectable levels. Results of the fish samples are given in Table 2.2.3 1.

2.2.4.5 Direct Environmental Radiation Table 2.2.32 shows the quarterly values for the TLD sites. The data are typical of the normal background level in this area. During 1994 several TLDs were stolen as indicated in the Table.

2.2.5 KNOLLS ATOMIC POWER LABORATORY (KAPL), NISKAYUNA, SCHENECTADY COUNTY AND KESSELRING SITE, WEST MILTON, SARATOGA COUNTY This facility operates at two separate sites. KAPL is on the shore of the Mohawk River, east of Schenectady, where a small test reactor and hot cell facilities are operated. The Kesselring site is where prototype naval training reactors are operated for the U.S. Navy. The Latham Water District, Colonie Filtration Plant, which is located about 7 miles downstream from KAPL, uses the Mohawk River as a water source.

Figure 2.26 shows the location of the Kesselring facility in Saratoga County. Table 2.2.33 provides information on sampling sites for both locations.

2.2.5.1 Radioactivity in Air Gross beta activity at this location was within the normal range for background levels and 1-131 was below minimum detection levels. Weekly results are given in Table 2.2.34.

2.2.5.2 Radioactivity in Water Both locations show values typical of normal background levels for gross alpha, gross beta and tritium activity. Results of weekly samples at KAPL and monthly samples at Kesselring are given in Tables 2.2.35 and 2.2.36, respectively.

2.2.6 NL INDUSTRIES (DOE/NLI), COLONIE, ALBANY COUNTY The NLI site is approximately 10 acres in size, located just north of the border between the Town of Colonie and the City of Albany. The plant was involved in the production of uranium products from the 1950s until it stopped operating in 1980.

During 1987, the US DOE purchased the plant and started the on-site clean-up and remedial activities to remove soil contaminated with uranium from nearby properties.

The DOE is temporarily storing the soil from decontamination activities within the building until it can be sent to an approved low level radioactive waste disposal site.

Table 2.2.37 gives a description of the sampling sites and Figure 2.2-7 shows their location.

2.2.6.1 Radioactivity in Water Water samples were collected at Patroon Creek twice in 1994. The gross alpha and gross beta results from the April 8 sample (13+/-6 and 6+2 pCi/L, respectively) show an increase from previous samples. The results, though positive, are still below the action level to trigger more specific isotopic analyses. Results for these samples are given in Table 2.2.38.

2.2.7 NINE MILE POINT SITE, SCRIBA, OSWEGO COUNTY This site is located on the shore of Lake Ontario. Two electric utilities operate three nuclear power plants at the site. Niagara Mohawk Power Corporation operates both Nine Mile 1 (625 MWe) and Nine Mile 2 (1150 MWe). The New York Power Authority operates the Fitzpatrick Nuclear Station (821 MWe). All reactors are boling water reactors (BWRs) and take cooling water from Lake Ontario. Figure 2.2-8 shows the facility and some nearby sampling sites. Table 2.2.39 provides information on the sampling sites.

2.2.7.1 Radioactivity in Air Results for gross beta activity were within the normal range for background levels. 1-131 concentrations were below the minimum detectable level.

Weekly and quarterly results are given in Tables 2.2.40 and 2.2.41, respectively.

2.2.7.2 Radioactivity in Milk Results for monthly milk samples collected from three nearby farms show that naturally occurring K-40 contributes most of the radioactivity in the samples. Low levels of Sr-90 and tritium were measurable while Cs-137 and 1-131 were below minimum detection levels.

The tritium levels in milk are higher than those reported in previous years.

Release data from the utilities do not indicate higher releases to the environment. For a period during the last quarter the laboratory made a procedural change in how the milk samples were analyzed for tritium which may have resulted in reporting higher concentrations than the true values.

Results from the three nearby farms are presented in Tables 2.2.42 to 2.2.44.

2.2.7.3 Radioactivity in Water Monthly grab samples from Lake Ontario showed typical background values for gross alpha, gross beta and tritium. A composite sample at the nearby City of Oswego water treatment plant also showed background levels.

Results from water samples are given in Tables 2.2.45 to 2.2.49.

2.2.7.4 Radioactivity in Sediment Table 2.2.50 shows the results of sediment samples. K-40 and other naturally occurring isotopes were detected as well as background levels of Cs-137.

Low, but measurable Co-60 concentrations were also observed.

77

2.2.7.5 Radioactivity in Vegetation Vegetable samples were collected in Oswego. The results indicate background levels of activity and are shown in Table 2.2.5 1.

2.2.7.6 Radioactivity in Fish Fish samples show that naturally occurring K-40 is responsible for most of the activity. Trace amounts of Cs-137 were detected in the sample. The results are presented in Table 2.2.52.

2.2.7.7 Direct Environmental Radiation (TLD)

Values recorded by the TLD monitors were typical of the normal background radiation levels for these locations and are shown in Table 2.2.53.

2.2.8. SELF-POWERED LIGHTING (SPL), ELMSFORD, WESTCHESTER COUNTY This facility utilizes large quantities of tritium in the manufacture of various self-luminous devices at this location. Figure 2.2-9 shows the facility location and some nearby sampling sites. Table 2.2.54 provides information on the sampling sites.

2.2.8.1 Radioactivity in Air Air samples collected near the SPL show measurable HTO levels. The results for 1994 range from less than 1.6 to 6.5 pCi/m 3 . These results are lower than the 1993 results of 1.0 to 15.5 pCi/m3 . Bi-weekly results are presented in Table 2.2.55.

2.2.8.2 Radioactivity in Water Water samples show measurable levels of tritium in samples collected near the SPL facility ranging from <200 to 680+/-160 pCi/L. All samples were well below the USEPA safe drinking water standard of 20,000 pCi/L.

Yonkers water treatment plant results were also below the safe drinking water standard. Figure 2.2-10 shows the annual average tritium (H-3) level at the Yonkers water treatment plant from 1979 to 1994. The highest recorded value of 340+/-160 pCi/L, is less than the largest 1993 value of 520+140 pCi/L. Results for the other nearby sites show a maximum tritium concentration of 220+/--140 pCi/L. Weekly results from the Yonkers Water Treatment Plant and the Tributary to Saw Mill River are given in Tables 2.2.56 and 2.2.57, respectively. Monthly samples from other nearby locations are given in Table 2.2.58.

2.2.8.3 Radioactivity in Fallout Weekly fallout (rainfall) samples were collected and results showed measurable levels of tritium. This sample was collected near the air sampler across the street from SPL. Low levels of tritium are measurable in these samples. Biweekly results are presented in Table 2.2.59.

2.2.9 SHOREHAM NUCLEAR POWER STATION, SHOREHAM, SUFFOLK COUNTY The Shoreham nuclear power plant is located in the Town of Shoreham on Long Island Sound. Its reactor was designed to operate at a power level of 849 MWe. The reactor was never operated at more than 5 percent of full power during initial testing and it has been shutdown since May 1991. The power reactor was decommissioned in 1994 under an agreement between New York State and the Long Island Lighting Company.

Figure 2.2-11 shows the Shoreham site and nearby sampling locations. Table 2.2.60 provides information on the sampling sites.

2.2.9.1 Radioactivity in Air Gross beta activity of air samples collected at this location was within the normal range for background levels. Due to the completion of decommissioning, the Shoreham air sample station was discontinued June 21, 1994. Weekly air sample results are given in Table 2.2.61. Composite quarterly results are given in Table 2.2.62.

2.2.9.2 Radioactivity in Milk No commercial dairy farms are operating near this site, and the last such farm went out of business in 1992, therefore no milk samples were collected in 1994.

2.2.9.3 Radioactivity in Water Water samples collected from Long Island Sound showed fission product activity to be below minimum detection levels. Results of these samples are given in Tables 2.2.63 and 2.2.64.

2.2.9.4 Radioactivity in Fish Fish samples results show that naturally occurring K-40 is responsible for most of the activity. Concentration of Ru-106, Cs-134 and Cs-137 were all below detection limits. Fish sample results are given in Table 2.2.65.

2.2.9.5 Direct Environmental Radiation (TLD)

Four locations near the Shoreham site showed quarterly readings typical for normal background radiation levels in this area. Values recorded by the TLD monitors were typical for these locations, and are shown in Table 2.2.66.

2.2.10 WEST VALLEY DEMONSTRATION PROJECT SITE (WVDP/DOE)

(FORMERLY NUCLEAR FUEL SERVICES), ASHFORD, CATTARAUGUS COUNTY The West Valley site is located about 35 miles south of Buffalo. The site is 3,345 acres in size and contains an inactive commercial low level radioactive waste burial site and a federally licensed burial site. The former Nuclear Fuels Services (NFS) reprocessing plant is also located on the site. The site is owned by New York State Energy Research and Development Authority (NYSERDA), the 200-acre former reprocessing facility is now operated by Westinghouse for DOE as the West Valley Demonstration Project to investigate methods of encapsulation of high level radioactive waste for permanent disposal. DOE took over responsibility for this site in February 1982. The project will encapsulate the high level waste currently stored on the site from the previous NFS nuclear fuel processing activities, and in the process decontaminate the facilities used by the project at the site.

Figure 2.2-12 shows the location of the site and some nearby sampling locations.

Table 2.2.67 lists these sampling sites.

2.2.10.1 Radioactivity in Air Gross beta activity at this location was within the normal range for background levels. Weekly and quarterly air sample results are given in Tables 2.2.68 and 2.2.69, respectively.

2.2.10.2 Radioactivity in Milk Results for monthly milk samples collected from a nearby farm showed that naturally occurring K-40 contributed most of the radioactivity in the samples.

Low levels of Sr-90 were measurable while Cs-137 and 1-131 were below detection levels. The Sr-90 concentrations are typical for atmospheric fallout and are found in milk samples taken throughout the state. Levels of HTO were in the range of less than 160 to 3,300 pCi/L. Results of monthly milk samples are given in Tables 2.2.70 and 2.2.71.

2.2.10.3 Radioactivity in Water Water samples are collected on and around the WVDP site. The main water pathway leaving the site is Erdman Brook which flows into Buttermilk Creek. The water then flows into Cattaraugus Creek and then into Lake Erie.

Cattaraugus Creek has a much larger flow rate and is the first offsite sample location.

111

On-site sampling locations show low levels of alpha, beta and tritium activity. The samples from the swamp drainage shows measurable fission product activity as it has over the years. Concentrations are well below the State Sanitary Code limits for release to uncontrolled areas (Attachment B).

Samples from Buttermilk Creek, downstream of the WVDP discharge point, show low levels of beta activity. Cattaraugus Creek shows occasional low levels of activity near the point where Buttermilk Creek flows into it.

Monthly and quarterly water sample results for these locations are given in Tables 2.2.72 to 2.2.80.

Figures 2.2-13 and 2.2.14 show the trends in annual averages for tritium (HTO) and Sr-90 respectively, in Cattaraugus Creek at the Springville dam.

Both HTO and Sr-90 were very low at Springville Dam. These levels reflect atmospheric fallout and reconcentration via surface water runoff.

2.2.10.4 Radioactivity in Sediment Tables 2.2.81 and 2.2.82 show the results of sediments from two different locations.In addition to naturally occurring radionuclides, Cs-137 concentrations of 228+/- 17 pCi/Kg was measured in the sediment sample taken from the Springville Dam location and 48+/-12 pCi/Kg in the Buttermilk Creek sample. The results show no difference from previous years.

2.2.10.5 Radioactivity in Vegetation Vegetable samples continue to show background levels of activities.

Naturally occurring K-40 exhibited the greatest activity. Results of vegetable samples from area farms are presented in Tables 2.2.83 and 2.2.84.

2.2.10.6 Radioactivity in Fish Fish samples were collected at Springville Dam and at Arcade (background).

Both sites show background levels of activities. Naturally occurring K-40 is responsible for most of the activity. Sample results are shown in Tables 2.2.85 and 2.2.86.

2.2.10.7 Radioactivity in Deer Deer samples were collected both on-site and off-site. These samples continue to show low levels of radioactivity. The on-site sample indicates trace amounts of Pu-239 (0.25 +/- 0.18 pCi/kg). Complete results are given in Table 2.2.87.

112

2.2.10.8 Direct Environmental Radiation Quarterly TLD values are typical for this area. The TLD near the new waste storage location shows high readings, as expected. Actual exposure to anyone on the site is much lower than the TLD results show since such people will not spend 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> per day at this location. In addition, workers at the site have individual personal monitors, which determine their radiation doses.

Table 2.2.88 shows the results and location of TLD sites used to monitor external radiation levels.

2.3 Non-Routine Sites 2.3.1 CORNELL UNIVERSITY, ITHACA, TOMPKINS COUNTY The Comell University burial site is located off the main campus, adjacent to Snyder Road, close to Tompkins County Airport. This fenced-in site, operated between 1956 and 1978, is approximately 300' x 300' in size. Ninety-eight percent of the buried material was C-14 and H-3; the other two percent was short-lived fission products from crop and animal experiments.

Water samples were taken in the vicinity of the Cornell University burial site in Tompkins County. Samples have been collected since 1966 from a stream, pond and private wells near the site and low to non-detectable levels of activity were found over this time period. Results of water samples taken at various locations are shown in Table 2.3.1.

2.3.2 EAD METALLURGICAL INC., TONAWANDA, ERIE COUNTY From 1977 to 1983 this site produced Am-241 foils which were used in the manufacture of smoke detectors. The plant was closed in 1983 and attempts were made to remove residual Am-241 contamination so the building could be released for unrestricted use. In 1984, contamination was discovered in the sewer lines leading from the EAD facility. The location of this site is shown on Figure 2.3-1.

In 1993 NYSDOH and NYSDEC conducted characterization surveys of the contaminated building and grounds. In 1994 the building and property were cleaned up and returned to the original owner.

Samples collected from the sewage treatment plant showed Am-241 contamination in sewage sludge, incinerated sludge ash and at the nearby landfill. Ash had been disposed of at the landfill and was used as covering material. A program monitoring sewage sludge and ash was instituted in 1984 and was continued through 1994.

Table 2.3.2 shows the 1994 Am-241 data for ash samples collected in Tonawanda.

Concentrations ranged from below the minimum detection level of 0.04 to 9.7+/- 0.6 pCi/g. Figure 2.3-2 shows the long term data for ash samples. Table 2.3.3 shows the Am-241 data for sludge samples. Concentrations in sludge ranged from below the minimum detection level of 0.03 to 0.3 pCi/g.

2.3.3 NRD, INC., GRAND ISLAND, ERIE COUNTY This facility currently manufactures smoke detector foils containing Am-241.

Am-241 was discharged directly to the sanitary sewer system prior to 1984.

Following the discovery of the EAD problem, samples were collected in the Grand Island sewage treatment plant and measurable levels of Am-241 were found in the sludge. This plant disposed of the sludge in a local landfill. NRD installed a new treatment system for its waste water in 1984 and reduced the quantity of Am-241 released to the sanitary sewer. Table 2.3.4 shows the 1994 Am-241 data for sludge samples collected in Grand Island. Figure 2.3-3 shows the long-term data for sludge samples. Samples collected in 1994 were in the range of 1.33 to 30 pCi/g.

Beginning in 1990, the sludge from Grand Island was sent to Buffalo for incineration with Buffalo's sewage sludge. Several samples of ash from the Buffalo incinerator were analyzed but all Am-241 levels were below minimum detection levels. This is not unexpected since the volume of Buffalo's sludge is much greater than that from Grand Island. Any Am-241 present in Grand Island sludge will be diluted by the larger volume of Buffalo sludge.
