I. INTRODUCTION r
i This report contains a summary and analysis of the radiological data j collected during 1982 by the EnvJronmental Studies Laboratory of the Vermont i Yankee Nuclear Power Corporation.
We measure direct gamma radiation in the station environs with CaF2:
Mn TLD bulbs in energy compensating shields. Vermont Yankee personnel prepare, distribute, measure and calibrate these dosimeters. We refer all measurements of radionuclide concentrations to an off-site environmental r radioactivity laboratory. All the environmental samples were processed by the l
' tankee Environmental Laboratory, located in Westborough, Massachusetts.
1 Section II of this report contains a list of all sampling stations used in 1982 as well as a tabulation of the media sampled at each station. Figures 1 through 4 indicate the location of the plant site, its topography and the locations of the sampling stations.
Section III summarizes the environmental data. A computer program, ERMAP, produces a digest of the 1982 measurements.
Section IV of this report discusses the Quality Assurance program, which includes EPA results, and Section V discusses fallout from a Chinese atmospheric nuclear weapons test. In the final sections, we analyze the results of our efforts in 1982, calculate environmental radiation doses, and present our conclusion.
II. LOCATION OF SAMPLING STATIONS t The following two pages list our sampling locations. Distances and t
crimuths are measured from the plant's stack and directions are relative to l true north. The media codes are:
AP Air particulate CF Charcoal air filter FI Finfish r TM Milk
(
SS Sediment f VA Aquatic vegetation VT Cattle feed WG Fresh water WR River water FD food crops TG Mixed grasces GM Direct radiation I

SUMMARY
OF 1982 ENVIRONMENTAL DATA The following pages summarize the analytical results of all the environmental samples which were collected during 1982. These pages were f generated by the computer program, ERMAP. Each environmental media appears according to the alphabetical order of its media code. At the top of each page, ERMAP lists the units of measurements for each media. The left hand column contains the radionuclide which is being reported, total number of analysis of that radionuclide, and the number of measurements which exceeds ten times the yearly average background value. The latter are called
, "non-routine" measurements. The next column lists the Lower Limit of Detection (LLD) for those radionuclides which have detection capability requirements as specified in the USNRC's Radiological Assessment Branch i
Technical Position (Rev. 1, 1979). (Guidance is not given for many of the radionuclides routinely measured and reported herein.) LLDs equal to or less I than these values are achieved greater than 95 percent of the time.
ERMAP calculates a set of statistical parameters for each l
radionuclide. This set of statistical parameters includes separate analyses for (1) the indicator stations (2) the control stations, and (3) the station having the highest annual mean concentration. For each of these three groups l of data, ERMAP calculates:
I
- 1) The mean value of all concentrations including negative values and values below MDC.
- 2) The square root of the mean square deviation. This is an estimate of the l sample variance.
l
- 3) The lowest and highest calculated concentration.
1 l
- 4) The number of positive measurements (activity which is three times greater l
than the standard deviation) divided by the total number of measurements.

IV. QUALITY ASSURANCE PROGRAM i
( Three separate Quality Assurance programs were performed during 1982 to demonstrate the validity of laboratory analyses by the Yankee Environmental Laboratory (YEL).
YEL participates in the EPA Interlaboratory Comparison (cross-check) program for those species and matrices routinely analyzed by the laboratory.
This provides an independent check of accuracy and precision of the laboratory analysis. When the results of the cross-check analysis fall outside of the control limit, an investigation is made to determine the cause of the problem and corrective measures are taken.
YEL maintains an intralaboratory quality control program to assure the validity and reliability of the data. This program includes quality control of laboratory equipment, use of reference standards for calibration, determination of counting efficiencies and analysis of blank and spiked samples. The records of the quality control program are reviewed by the responsible cognizant individual, and corrective measures are taken whenever applicable.
A blind duplicate / replicate program is maintained in which samples are prepared from split or homogeneous media and sent to the laboratory for analysis. The results from this blind duplicate program are used to check for precision in laboratory analyses.
EPA Interlaboratory and Intralaboratory Results The Quality Assurance program implemented at the analytical laboratory indicated good precision and accuracy in reported values. Table 2 shows the results of accuracy and precision for laboratory analyses in 1982 for EPA samples, intralaboratory analyses and interlaboratory cross-check analyses.
For accuracy, 55.4 and 73.1 percent of the results were within 5 and 10 percent of the known values, respectively, with 95.1 percent of all results falling within the laboratory criteria of 15 percent. For precision, 65.7 and 80.5 percent of the results were within 5 and 10 percent of the mean, respectively, with 98.4 percent of all results meeting the laboratory criteria of 15 percent.
l Blind Duplicate-Replicate Program 1
l A total of 72 paired samples were submitted for analysis during 1982.
The data base used for the duplicate-replicate analysis consisted of paired
( measurements of 26 gamma emitting nuclides, tritium, Strontium-89, Strontium-90, low level I-131 and gross beta. A dual level criteria for agreement is used. If the paired measurements fall within 1,15 percent of -
their average value, then agreement between the measurements has been met. If the value falls outside of the 1;15 percent, then a two sigma range (95 percent confidence level) for duplicates and a three sigma range (99 percent confidence level) for replicates is established for each of the analyses. If the ranges overlap, agreement is obtained. One thousand five hundred and seventy-five paired duplicate and replicate measurements were analyzed for 1982. A total of 99.2 percent of all measurements fell within the established criteria discussed above. Of the 0.8 percent of the measurements which fell outside of the criteria, most of these were made up of fallout and plant-related radionuclides (Cs-134, Cs-137 and Co-60) contained in sediment i
samples. This poor agreement can be attributed to non-uniform distribution of man-made radionuclides in the sediment, rather than poor precision in laboratory analysis.

V. ATMOSPHERIC FALLOUT DURING 1982 In October of 1980, the People's Republic of China detonated a nuclear device in the atmosphere in Northwest China. The clouds of radioactive debris began drifting over the United States shortly thereafter. During the latter part of 1980 and throughout much of 1981, increased radioactivity was seen in ,
sampled media of most types (Reference 2). Long-lived radionuclides from this test and other previous tests can still be detected in significant quantities k in other sampled media. Due to physical depletion of the contaminants in the ..
atmosphere, along with their radioactive decay, very little of this radioactivity was seen in air particulate samples during 1982.

VI. ANALYSIS OF ENVIRONMENTAL DATA l
The analysis of environmental data may be divided into three sections:
airborne radioactivity, waterborne radioactivity, and direct exposure measurements. A discussion of each environmental media within these sections will follow.
- 1. Airborne Pathway
- a. Air Particulate and Gaseous Radioiodine Air monitoring stations are established at a total of nine locations.
Airborne particulates were collected by passing air through a fiberglass filter. These filters were collected weekly and analyzed for gross beta activity. Weekly filters from each location were composited for the calendar quarter and were analyzed for gamma l emitting nuclides.
Gross beta counts (Figure 6) showed random fluctuations at all sampling locations including controls. Two data points were left out of the ERMAP summary tables and the curve in Figure 6. These were for Stations 22 and 23 (both controls) for the week of June 22-29, 1982.
Due to improperly aligned air particulate filters, the sampled air volume, and consequently the gross beta air concentration, could not be determined. (Control Station 21 was operating properly and did provide control data for that period.)
{
Cs-137 was detected on air particulate filters at Station 13, an indicator, and at Station 23, a control (see Figure 7). In both cases, the concentrations were approximately equal to the three sigma level which determines whether a count indicates positive activity or not, and also in both cases the counts were below their respective MDCs. Cs-137 was also detected at the control air sampling station in Westboro, Massachusetts during 1982 (see Figure 5).
Co-60 was also detected at two air sampling stations (see Figure 8).
The first, Station 14, showed a concentration slightly over the three sigma level and its respective MDC for the first quarter composite
100.

sample. The second, Station ll, showed a concentration close to the three sigma level and below the MDC for the third quarter composite sample. No Co-60 was detected in any other environmental samples.
This fact, along with the marginally detectable concentrations, indicates that the Co-60 measurements were either false positive measurements or were due to cross contamination of samples. If the Co-60 had, in fact, been in the sampled air during the above times and at the above locations, the total body dose to a person residing at each location during the respective release times would have been approximately .00002 mrem (to a child's total body) or for the i critical organ, .007 mrem (a teenager's lung).

Charcoal filters from nine air sampling locations were collected and analyzed weekly for I-131 activity. During 1982, no I-131 activity was detected in charcoal filter samples.

- c. Milk Milk samples were collected from three indicator and one control location and analyzed monthly for gamma emitters and quarterly for Sr-89 and Sr-90 activity. As usual, Cs-137 and Sr-90 activities were detected in samples submitted from indicator and control locations (see Figures 9 and 10). The ERMAP milk table shows that the average concentration of Cs-137 and Sr-90 was higher in control station milk, indicating that Cs-137 and Sr-90 levels in milk were due to residual activity from atdospheric nuclear weapons testing.
- d. Mixed Crasses Grass samples were collected in June, August and October from nine sampling locations and were analyzed for gamma emitting nuclides. The radionuclides observed at levels above minimum detectable concentrations were the naturally occurring radionuclides K-40 and Th-228, cosmic produced Be-7, and Cs-137 (see Figure 11). Cs-137 was detected at control as well as indicator stations. The highest

concentration, and the only one at a level higher than found at control stations, was 337 pCi per Kg at Station TG 15, collected on June 8, 1982. No Cs-137 activity was detected on the air particulate sampler at this same location during all of 1982. Additionally, site meteorological data were correlated with measured plant releases of Cs-137 for this period. Both of these indicated that the measured off-site levels could not be due to plant releases. This, along with the absence of Cs-134, strongly indicates that the measured Cs-137 was due to nuclear weapons testing fallout.
- e. Food Products Food products were collected from four sampling locations and analyzed for gamma emitting radionuclides. Potassium 40, a naturally occurring radionuclide, was the only gamma emitter detected.
- 2. Waterborne Pathway
- a. Fish Fish samples were collected in June and October from two indicator and one control location. Edible portions of the samples were analyzed for gamma eeitting nuclides. Cs-137 and naturally occurring K-40 were the only radionuclides detected. Comparisons of indicator Cs-137 concentrations to control samples show that the control had a higher average concentration, and this activity can be attributed to nuclear weapons testing fallout,
- b. Aquatic Vegetation Aquatic vegetation samples were collected from two locations and analyzed for gamma emitting nuclides. Naturally occurring K-40 was the only radionuclide detected.

- c. Sediment Sediment samples were collected in June and October from one control and two indicator stations and were analyzed for gamma emitting nuclides. Naturally occurring K-40 and Th-228 plus man-made Cs-137 were the only radionuclides detected. The Cs-137 detected at indicator stations was not significantly different from that detected at the control station, nor have the concentrations at either changed significantly from the levels detected in 1981 (Reference 2). This activity can consequently be attributed to fallout from nuclear weapons testing.
- d. River Water River water was collected from three locations and analyzed monthly for gross beta and gamma emitting nuclides. The monthly samples were composited and analyzed for H-3 on a quarterly basis. Gross beta activity was detected in most samples, but since the control samples showed higher levels of activity than the indicator samples, the activity can be attributed to naturally occurring and/or fallout-related radionuclides (see Figure 12). H-3 was detected in one composite sample from Station 11. The concentration was, however, similar to background levels seen in surface water samples in the U.S.
(see Figure 13).
- e. Ground Water Ground water samples were collected and analyzed quarterly for gross beta, tritium and gamma emitting nuclides. The only detectable concentration in ground water samples was gross beta. Gross beta activity was detected in indicator and control locations and the concentrations are typical of concentrations made over the past few years. The mean concentration at indicator stations given in the ERMAP tables is skewed high due to one sample from Station 11.
Investigation showed that the unusually high count was most probably due to cross contamination. When the data from the blind duplicate sample, that had been split from the original, is substituted for the

- 3. Direct Radiation Direct gamma radiation is measured with Ca F2 : Mn thermoluminescent dosimeters (TLD's). The TLD's are collected monthly from 21 locations on and off the Vermont Yankee site. Table 3 shows the yearly average exposures in pR per hour and this table shows that off-site Zone I locations exhibited gamma radiation which ranged from 7.7 to 23.8 jar per hour which compares to the 7.7 to 8.2juR per hour at control locations.
' When one re-computes the mean exposure rate at indicator stations without including Station GM 1.14, the measured radiation levels are closer to that of the control locations. The mean in this case is 9.0 + 0.8 jar per hour with a range of 8.1 to 10.8. (Station GM 1.14 is located on the west shore of the Connecticut River, well within the site boundary and close to I
the Containment and Turbine Buildings, and as such, does not truly j represent off-site exposure rates.) The slightly higher average exposure i
j rate at indicator locations, when compared to the average exposure at control locations, is due to variations in natural background radiation, and the average exposure rates are not significantly different.

VII. ENVIRONMENTAL DOSIMETRY The mean concentration of radionuclides having detectable concentrations (i.e., greater than three sigma) in indicator and control station samples of air particulate filters, charcoal filters, drinking water, equatic food, milk, and food crops were used to calculate total body doses to cdults. The average individual usage factors were taken from USNRC Regulatory Guide 1.109 (Reference 1). These usage factors are:
8000 M per year of inhaled air 370 liters per year of drinking water 6.9 Kg per year of aquatic food 110 liters per year of milk 190 Kg per year of food products The product of the mean radionuclide concentration greater than three sigma and the usage factor yields the yearly radionuclide intake. The dose is calculated by using the dose conversion factors contained in USNRC Regulatory Guide 1.109. In addition, external whole body doses were measured with TLDs placed in indicator and control stations.
Table 4 summarizes the environmental doses at indicator and control stations. The doses calculated from inhalation, ingestion of aquatic food, ,
water and milk were due to concentrations of radioactivity related to atmospheric nuclear weapons tests. TLD measurements at indicator and control locations were not statistically different, indicating that the dose is from natural background and fallout radiation in Vermont.

VIII. CONCLUSION During 1982, our Radiological Environmental Monitoring Program conducted in the environs of Vermont Yankee showed, in general, that the radionuclides measured in environmental media were naturally occurring and fallout products from atmospheric nuclear weapons tests. There was no detectable increase in environmental radioactivity due to the operation of Vermont Yankee.
The levels of radioactive materials in the environment indicate that public intake was less than one percent of those recommended in Appendix B, Table II, of Title 10, Part 20 of the Code of Federal Regulations.
