Executive Summary This 1993 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).

I. 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. DOH adopts the public health position that unnecessary exposure to radiation from man-made sources and radioactive materials releases to the environment should be as low as reasonably achievable.

A. 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, thermoluminescent 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

B. 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 for Laboratories and Research (WCL&R) then analyzes these samples using a variety of equipment and appropriate methods for the 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. The WCL&R can provide more detailed information on sample preparation, analysis and quality assurance programs.

1. Water Samples usually consist of 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, or gross beta activity exceeds 50 pCi/liter, gamma spectral analysis is performed to identify the particular radionuclides present in the sample.

2. Milk Two liter samples of milk are collected near facilities which may release fission products such as 1-13 1, 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.

3. 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.

a. 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.

2

b. Activated Charcoal Cartridges The Department uses activated charcoal to collect the various radioisotopes of iodine. Analysis is by gamma spectroscopy or radiochemical 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 WCL&R uses this method for samples taken near the Cintichem facility.

c. 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.

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 tritium (HTO) at Elmsford, Westchester County.

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.

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.

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, Pu-238, Pu-239 or 1-129 are measured in flesh, thyroid and lung tissue. Fish samples are analyzed as whole fish (meat plus bones with head and tail cut off) or may be separated into flesh and bone components which are then analyzed individually.

3

C. Types of Sampling Sites Sampling sites are generally of three types, i.e., background,' routine nuclear and nonroutine sites. A list of New York State sampling sites is shown in Appendix A.

1. 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.

• 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.

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

4

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

Nuclide Concentration (pCi/1)

Sr-90 20 +/- 5 Sr-90 <8 Sr-90 Not Reportable or No Sample 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 maximum annual average concentrations allowed by the New York State Sanitary Code, Part 16 in air and water discharges to unrestricted areas are given in Attachment B. These 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.

Data for the various sites of interest are presented in Tables 1-10. Data are grouped by type of sample, by county and by date as shown below:

IlI. Results A. 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 1 shows the location of the background sites (1-7) and Table 1 gives the sample type and collection frequency. Data for these locations are included in the data tables of this report. This allows comparison to other locations of interest. The Empire State Plaza (ESP) is located in downtown Albany and is the location of the DOH Wadsworth Center Labs and Research (WCL&R) laboratories. Air and fallout samples in Albany are collected at the roof of the Albany County Health Department in Albany, New York.

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 (5E-3) to 0.02 (2E-2) pCi/m3 . The naturally occurring radionuclide Be-7 is measurable in quarterly composite samples.

7

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 1100 to 1600 pCi/l. This year low levels of the fallout radionuclides Sr-90 and Cs-137 were measured. The Cs-137 values were below minimum detection levels except for one sample collected on 06/29/93 where the value was 17 + 12 pCi/l, which is about two to three times the minimum detection level of 6 to 8 pCi/l. Figure 2 shows the annual average levels of Cs-137 and Sr-90 for 1963 through 1993. Values for the radioiodines (1-125, 1-129, 1-13 1) are all below minimum detection levels.

3. Radioactivity in Water Background water samples show typical levels of radionuclides for drinking water or environmental samples. Gross alpha levels are typically below 2 pCi/liter and beta levels are typically below 4 pCi/liter. Tritium (HTO) is typically below 200 pCi/liter except one sample collected on (03/01/93 - 03/05/93) which was 600 + 150 pCi/1.

Fallout fission products were at or near minimum detectable levels.

B. 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 thermal megawatt (MWt) High Flux Beam Reactor (HFBR) and the 5 MWt Medical Research Reactor (MRR). Other nuclear facilities include hot cells and storage areas for spent reactor fuel. Figure 3 shows the facility and some nearby sampling sites.

1. Radioactivity in Air Results of gross beta activity in air were within the typical range for background levels of less than 0.02 pCi/m3 . Due to BNL reconstruction of their on-site sampling building in which our air sampler was kept, therefore, no air samples were collected after March 24, 1993.

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

3. Radioactivity in Water Monthly samples were collected from the Peconic River which is near this facility.

Gross alpha and gross beta activity were typical for background levels. Measurable levels of tritium were found to range between 600 to 3,600 pCi/1. Although some of the samples showed elevated tritium levels, the measured values were well below the EPA drinking water standard of 20,000 pCi/l. The most likely source of the tritium is movement of contaminated groundwater or surface runoff from the BNL site.

Figure 4 shows the average annual value of tritium measured in the Peconic River from 1974 to 1993.

4. Direct Environmental Radiation Values recorded by the TLD monitors were typical for normal background radiation levels at these locations, and are shown in Table 11 around the Shoreham Nuclear Power Station which is close to BNL.

5. Other Table 6 shows results for fish samples collected from several ponds near BNL. As in previous years, these samples show elevated levels of Cs-137 and Sr-90 compared to samples from other locations. The Sr-90 is found almost entirely in the skeleton while Cs-137 is distributed primarily in the flesh. The analysis was performed on the whole fish. A person consuming 26 kilograms of fish per year containing 300 pCi/kg of Cs-137 would receive a committed effective dose equivalent of only 0.4 mrem.

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.

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 were measurable while Cs-137 and 1-131 were below minimum detection levels. The Sr-90 concentrations are typical for the atmospheric fallout contribution and are found in milk samples taken throughout the state.

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. Monthly samples from the discharge canal (5857-005) showed minimum detectable levels of activity.

F. 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 since the 1950s until it stopped its operation in 1980.

During 1987, the Department of Energy (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 temporarily stores the soil within the building until final disposal, in an approved low level radioactive waste disposal site, can be arranged.

1. Radioactivity in Air Air samples collected near the SPL show measurable levels of tritium (HTO). The 1993 range of results are 1.0 to 15.5 pCi/m3 compared to the 1992 results with a range of 2.0 to 64 pCi/m 3 .

2. Radioactivity in Water Water samples show measurable levels of tritium in samples collected near the SPL facility, but all samples were well below limit for release to the environment. Yonkers water treatment plant results were all below the U.S. Environmental Protection Agency (USEPA) guideline for tritium in drinking water (20,000 pCi/l.) Figure 10 shows the annual average tritium (H-3) level at the Yonkers water treatment plant from 1979 to 1993. Levels have fallen to below 300 pCi/l over this period.

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.

I. 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 12 shows the location of the site and some of the nearby sampling points. Table IX provides information on the sampling sites.

Table 11 shows the location of the TLD monitors used to measure the external background radiation level.

In 1990 Cintichem shut down the reactor following the discovery of environmental contamination. The reactor and radioisotope processing hot cells were being decommissioned in 1993.

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.

2. Radioactivity in Milk Due to the fact that the farmer who previously supplied milk samples went out of business and Cintichem was being decommissioned, no milk samples were collected in 1993.

3. Radioactivity in Water Several water samples from Indian Kill were collected and showed HTO concentrations, which ranged from less than detectable levels to 11,100 pCi/l.

J. 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. This 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 site.

Figure 13 shows the location of the site and some nearby sampling locations. Table X lists these sampling sites. Figure 14 shows the location of on-site sampling, which is also listed in Table X. Table 11 shows the results and location of TLD sites used to monitor external radiation levels.

1. Radioactivity in Air Gross beta activity at this location was within the normal range for background levels.

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.

3. Radioactivity in Water Water samples are collected on and around the West Valley 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.

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.

Figures 15 and 16 show the trends in annual averages for tritium (HTO) and Sr-90 in Cattaraugus Creek at the Springville dam. Sr-90 levels ranged from <6 to 7 + 6 pCi/l.

These levels reflect atmospheric fallout and reconcentration via surface water runoff.

4. Direct Environmental Radiation (TLD)

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 personnel monitors, which determine their radiation doses.

35

5. Other Deer, fish and vegetable samples collected continue to show low levels of radioactivity. Naturally occurring K-40 exhibited the greatest activity.

K. Shoreham Nuclear Power Station, Brookhaven, 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 is being decommissioned under an agreement between New York State and the Long Island Lighting Company.

Figure 17 shows the Shoreham site and nearby sampling locations. Table XI provides information on the sampling sites.

1. Radioactivity in Air Gross beta activity of air samples collected at this location was within the normal range for background levels.

2. Radioactivity in Milk Due to close out of the dairy business in the Long Island area no milk sample was collected in 1993.

3. Radioactivity in Water Water samples collected from Long Island Sound showed fission product activity to be below minimum detection levels.

4. Direct Environmental Radiation Four locations near the Shoreham site showed quarterly readings typical for this area.

5. Other Fish samples (Table 6) show that naturally occurring K-40 is responsible for most of the activity. Other radionuclides were at typical background levels.

Sediment samples (Table 7) taken near the discharge point show typical levels.

Vegetation samples (Table 8) were obtained from nearby locations and showed only typical background levels of radioactivity.

L. Non-Routine Sites

1. EAD Metallurgical Inc., Tonawanda, Erie County From 1977 to 1983 this site produced Am-241 foils which were used in 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 use. In 1984, contamination was discovered in the sewer lines leading from the EAD facility. The location of this site is shown on Figure 18. In 1993 NYSDOH and NYSDEC condcuted characterization of the contaminated building and grounds.

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 which was instituted in 1984 was continued through 1993.

Table 9 shows the 1993 Am-241 data for ash samples collected in Tonawanda.

Concentrations were below the minimum detection level of 0.4 to 3 pCi/g. Figure 19 shows the long term data for ash samples. Table 10 shows the Am-241 data for sludge samples. Concentrations in sludge were below the minimum detection level of 0.2 to 1.7 pCi/g.

2. NRD, Inc., Grand Island, Erie County This facility currently manufactures smoke detector foils containing Am-24 1. 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 10 shows the 1993 Am-241 data for sludge samples collected in Grand Island. Figure 20 shows the long-term data for sludge samples. The Am-241 levels have dropped from 1984 to 1989. Samples collected in 1993 were slightly higher than the results of the previous year, being in the range of about 1 to 84 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.

3. Cornell University, Ithaca, Tompkins Co.

The Cornell 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 2 percent was short-lived fission products for crop and animal experiments.

Water samples were taken in the vicinity of Cornell University site (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 for 1993 show that low levels of H-3 were found near the burial site.
