1.0 INTRODUCTION
This report describes the Radiological Environmental Monitorinq Program (REMP) for the Waterford 3 Steam Electric Station and discusses the results obtained (Wing the calendar year 1991. The results discussed in this report were used to evaluate the radiological environmental impact resulting from the operation of Waterford 3. The submission of this report to the Nuclear Regu!atory Commission (NRC) fulfills the requirements pursuant to Waterford 3 Technical Specification 6.9.1.7. 1.1 Procram and Roo. ort Objegives The objective of the monitoring program is to evaluate the radiological environmental impact of the plant. In order to conduct this evaluation, the data analyses and interpretations contained in this report fulfill the following specific objectives; a. to identify any radioactive ma erials or radiation in the environment associated with plant operation, b. to compare the results obtained during the reporting period with past operational and pre-operational data and identify any trends associated with accumulation of radioactivity in the environment, and c. to verify compliance with federal regulatory requirements. 1.2 Plant and Site Descriotion Waterford 3 employs a pressurized water reactor for the production of approximately 1153 gross (1104 net) megawatts of electricity. The station uses a flow of water obtained from and discharged to the Mississippi River for condenser cooling, On March 4,1985, the unit achieved initial criticality. 1
The plant is located on the west bank of the Mississippi River at River Mile 129.6 between Baton Rouge and New Orleans, Louisiana. The site is in the northwestern section of St. Charles Parish approximately 3 miles southeast of the St. John the Baptist Parish boundary between the towns of Kiliona and Taft. The Mississippi River is the closest prominent natural feature; other features include Lac des Allemends, abcut 5.5 miles southwest of the site, and Lake Ponchartrain, about 7 miles northeast of the site. Most of the man made features are located on the narrow strip of land between the Mississippi River and the wetlands. Specifically, several A industrial facilities including Waterford 1 and 2 Steam Electric Stations (0.4 miles northwest), Little Gypsy Steam Electric Station (0.8 miles northeast), Agrico, a fertilizer manufacturer (0.6 miles east scutheast), Occidental Chemical Company (0.8 miles east southeast), and Union Carbide, a chemical manufacturer (1.2 miles east southeast) are operating in the area. Major urban centers in the region include New Orleans (aporoximately 25 miles east) and Baton Rouge (approximately 50 miles west northwest). Communities near the site in St. Charles Parish include Killona (0.9 miles west northwest), Montz (1.0 miles north), Norco (2.5 miles east), Hahnville (3.7 miles east southeast), and Destrehan (6.3 miles east southeast). Laplace (4.7 miles north) is located in St. John the Baptist Parish. 2.0 PROGRAM DESCRIPTION A general summary of the REMP is given in Table 2.1; brief descriptions anc4 locations of the sampling stations are presented in Table 2.2. In addition, station locations are illustrated in Figures 2.1 through 2.3. A more detailed description of the REMP is provided below. 2 1
2.1 _ History and Develgpment The Waterford 3 REMP evolved from the Pre-operetional Environmental Radiological Surveillance (PERS) program (1978-1982) and was initiated in April of 1983. Equipment, procedures, techniques, and sampling locations used during the pre-operationa! survey were incorporated into the operational program. Further, the environmental data collected during the first two years of the REMP (1983 and 1984), prior to initial criticality, were used to supplement the baseline established during the PERS Program. 2.2 Responsibilities Waterford 3 personnel are responsible for implementing and insuring that I the REMP complies with federal regulatory, Technical Specification, and Offsite Dose Calculation Manual (ODCM) requirements. Responsibilities of o Waterford 3 personnelinclude collecting (with the exception of fish I samples), preparing, and shipping of environmental samples; conducting enviror' mental dosimetry measurements; reviewing analyticci results reports; and preparing and submitting toe annual Radiological Environmental Monitoring and other relevant reports to the Nuclear Regulatory Commission. The primary contractor, the Environmental Services Department of Arkansas Power & Light (AP&L) located in Little Rock, Arkansas, is responsible for performing radiological analyses; conducting initial data review; preparing results reports; and overseeing laboratory quakty assurance and control. Additionally, a separate contractor, the Fisheries Co-coerative Extension Service of Louisiana State University, is responsible for the collection of fish samples. 2.3 Sample Collection and Handiino ! ueedures Sample types, location, collection frequency, and the analyses performed are surnmarized in Tables 2.1 and 2.2. The information contained in these tables is based on requirements specified in Table 5.8-1 of the Waterford 3 ODCM. Location maps of the sa~1pling stations are illustrated in Figures 2.1 through 2.3. Any deviations (i.e., unavailable samples and missed lower limits of detection) or changes made to the REMP during 1991 are discussed in Section 3.6. 3
The environmental samples collected are classified into four general categories according to exposure pathways: direct radiation, airborne, waterborne, and ingestion. Sample coliection and handling procedures are described in the following sections. The descriptions are intended to provide a concise procedural overview rather than a step-by-step description. 2.3.1 Direct Radiation Exoosure Pathway Samples Integrated external gamma exposure, determined using Panasonic Multi-element thermoluminescent dosimeters (TLDs), was measured at thirty-one locations as follows: a. an inner ring of stations, one in each of the sixteen meteorological sectors, in the general area of the site boundary; b. an outer ring of stations, one in ten of the sixteen meteorological sectors, in the six to eigh+ 1:ilometer range from the site; and c. the balance placed in areas of special interest (e.g., population centers, schools, etc.) with one area serving as a control. The TLDs weie exchanged and analyzed quarterly by Waterford 3 personnel. 2.3.2 Airborne Expgsure Pathway Sampin Samples of airborne particulates and radiciodines were collected at f?ur indicator stations (APP-1, APO-1, APG-1, APC-1) and one control station (APE-30). Low-volume air pumps and flow totalizers in weather proof shelters provided continuous air sampling. I 4
. Using the sampling device described above, airborne particulate l samples were obtained on a filter and collected weekly by Waterford 3 personnel for shipment to the contract laboratory for gross beta analysis. Tne filters were composited quaderly by the -l contract laboratory for isotopic analysis by gamma spectroscopy. Altborne iodine sampling was cone in conjunction with air particulate sampling using a charcoal cartridge to collect iodine. The cartridges were collected weekly by Waterford 3 personnel and sent to the contract labcratory for lodine-131 analysis by gamma spectroscopy. 2.3.3 Waterborne Exoosure Pathway Samoles
- Because the plant discharges into the Mississippi River, the major source of drinking water in the vicinity of Waterford 3, water samples taken from the Mississippi River were designated as both drinking and surface water samples.
Composite drinking / surface water samples were obtained biweekly from the Mississippi River using automatic composite samplers placed at one upstream (DWP 7/SWP 7) and two downstream (DWG-2/SWG-2, DWE 5/SWE 5) locations. Hydrochloric acid was added to each sample prior to shipment Tne contract laboratory analyzed the biweekly samples for iodine 131, composited them monthly for gross beta and gamma spectroscopy, and composited them quarterly for tritium analysis. .Due to the high water table resulting from shallow aquifers in the vicinity of the site, drainage canal sampling represents groundwater discharge. Groundwater was obtained quarterly by grab sampling from one sampling location (GWK-1). Apain, hydrochloric acid was added to the sample prior to shipment to the contract laboratory for tritium and gamma spectroscopy analyses. 5 1
U Shoreline sediment samples were obtained semi-annually from a l sampling station at each plant discharge point. Station SHWE-3 is located downctream on the shoreline of the Mississippi River; station SHWK-1 is on the shoreline of the 40-Arpent canal. The samples were shipped without further processing. 2.3.4 inaestion Exoosure Pathway Samoles Milk samples were collected semi-monthly from one indicator location (MKO-5) and one control location (MKO-45). Sampling of the control station was performed by Louisiana Radiation Protection Division personnel. Although one additionalindicator location was identified (MKE-4), no samples were available from this location during 1991 (see Section 3.6). Formaldehyde was added as a preservative to all samples prior to shipment lodine-131 and gamma spectroscopy analyses were performed. Fish samples were collected bi annually from the Mississippi River upstream (FH 1) and downstream (FH 2) from the plant. A contractor performed the sampling by netting. Subsequently, the fish were segregated by species and location prior to delivery to - Waterford 3. The samples were shipped frozen for analysis by gamma spectroscopy. The Waterford 3 ODCM, Section 5.8.1, requires broad leaf vegetation to be sampled from 3 locations within 5 miles of the . plant in the event milk samples are unavailable. Since milk samples were collected from only one sampling location within five miles of Waterford 3, broad leaf vegetation was sampled monthly at two indicator locations (BLO 1 and BLB-1) and one control location (BLK-15). The samples were shipped without further processing. Food product sampling was not required because no areas - surrounding the plant were irrigated with water in which plant wastes are discharged. However, food products grown within the site boundary were collected to demonstrate the absence of radionuclide accumulation. 6 w-
These food product samples (sugarcane and soybeans) were co!!ected at the time of harvest from three locations (FPP-1, FPG 1, and FPQ-1) by normal harvesting techniques and shipped without further processing, lodine-131 and gamma spectroscopy analyses were performed. 2.4 Analvtical Procedures A brief synopsis of the analytical procedures used by AP&L and Waterford 3 are given in Appendix D to provide an overview of the program.- The minimum sensitivities for the analytical procedures are reflected by the Lower Umits of Detection (LLD) values presented in Table 2.3 from Table 5.8-3 of Waterford 3 ODCM. The LLD's are a oriori estimates based on t assumed sample volumes, counting times, detector efficiencies, etc. Analyses that could not achieve these lower limits of detection are discussed in Section 3.6. 2.5 Laboratorv Ouality Assurance During 1991, AP&L performed between 5% and 10% of all analyses for quality assurance purposes. Spiked and blank samples were prepared in-house. In addition, AP&L' participated in the EPA Radiological intertaboratory Comparison (cross-check) Program. This_ quality assurance program satisfies the requirements of the Waterford 3 ODCM, Section 5.8.2, for participation in an interlaboratory cornparison l program. The. program involved analyses on various sample media l typically found in the REMP. As a result of participation in the program, an objective measure of analytical precision and accuracy was obtained, in the event that results obtained by AP&L were not within control limits (3 standard deviations), an investigation was conducted to determine the -cause, and corrective action was taken to prevent a recurrence. Appendix r C lists the 1991 results of AP&L's participation in the cross-check program. 7

l 3.0 DISCUSSION OF RESULTS Analytical results for the year 1991 are discussed in this section by exposure pathway, sample type. and analysis performed. Further, analytical results focusing only on man-made radioactivity are summarized in Appendix A; dcta for the individual analyses are presented in the tables of Appendix B. 3.1 . Direct Radiation Exposttry Pathway The average exposure rates measured by thermoluminscent dosimeters (TLDs) at both control and indicator stations were 12,13,12, and 13 mrem / standard quarter for the first, second, third, and fourth quarters of 1991 respectively. The average exposure rate of the 117 indicator TLD locations was 13 rarem/ standard quarter compared to 12 mrem / standard qvm r average exposure rate at the controllocation. The lowest and highest individual exposure rates were 7 mrem / standard quarter (C 1, 2nd and 3rd quar 1ers) and 19 mrem / standard quar 1er (G 9,1st quarter), respectively, for all locations. Table 3.1 compares the indicator TLD results by directional sector and distance from the facility. A comparison of 14 mrem / standard quarter directional sectors indicates the highest overage exposure rate to be in Sectors A, G and O. The average exposure rates during 1991 are consistent with those from the pre operational program and the previous five years of operation (Figure 3.1). Specifically, the pre-operational survey indicates that exposure rates ranged between 11 and 33 mrem / standard quarter. Similarly, the range indicated during the previous five years of operation was from 6 to 30 mrom/ standard quarter with an average exposure rate of 14 mrem / standard quarter. 3.2 Airborne Exposure Pathway 3.2.1 Airborne ParticuMtp3 Gross beta activity ranged from 0.005 pCi/m' (APO 1 and APP-1, 8/26-9/3) to 0.039 pCl/m' (G 1) (APG 1,11/5-11/11) with an average of 0.018 pCl/nf for 260 measurements from all five locations. The average gross beta activity for both control (APE-
- 30) and indicator (APG 1, APO 1, APP-1, APC 1) locations was 0.018 pCi/m.
The gross beta activity results obtained during 1991 are consistent with those from the pre operational program and the previous five years of operation (Figure 3.2). Specifically, the pre-operational survey indicates that in periods not significantly influenced by nuclear weapons testing the gross beta activity ranged between 0.006 and 0.08 pCi/rrf with an average of.02 pCi/m'. Similarly, the range indicated during the previous five years cf operation was from 0.003 to 0.05 pCl/n1 with an average activity of 0.02 pCi/m. 25 I
3.2.2 Altborne lodine All of the 264 airborne iodine 131 results were below the calculated lower limit of detection (LLD). The sample LLD variability (0.011 to 0.040 pCl/ cubic meter Table B 2) was due primarily to the difference in air sample volumes. 3.2.3 Gamma Isotoolc Analysis Gamma spectroscopy results of the twenty air sample quarterly composites indicate that no man made radionuclides were detected above their respective lower limits of detection. 3.3 . Waterborne Exoonpre Pathway 4 3.3.1 Drinkina/ Surface Water As mentioned previously, drinking water samples also serve as surface water samples for Waterford 3. Therefore, monthly and quarterly gamma spectral analysts of drinking water and quarterly tritium analyses also satisfy the surface water sampling requirement. Seventy eight composite drinking / surface water samples were analyzed by a radiochemical procedure for lodine 131 (Table B-4). Results from these analyses indicate that no activity was detected above the calculated LLD for lodine 131. Gross beta activity was detected in thirty five of the forty-two composites with a range of 1.1 (DWP 7,11/512/3) to 9.5 (DWG 2, 7/29-8/26) pCl/l and an average activity of 3.8 pCl/l. The average activity for the control location, DWP 7, was 3.9 pCl/l compared to the averages of 4.2 and 3.3 pCi/l for indicator stations DWG 2 and DWE 5 respectively. The gross beta activity results obtained during 1991 are consistent with those from the pre operational program and tha previous five years of operation (Figure 3.3). Specifically, the pre-operational survey indicates that in periods not significantly influenced by nuclear weapons testing the gross beta activity ranged between 3 and 14 pCi/l with an average of 7.0 pCi/l. Similarly, the range indicated during the previous five years of operation was from 2 to 60 pCl/l with ari average activity of 61.pCl/l. Tritium analysis of dricio g/ surface water samples indicate that-- n eleven of the twelve measurements were be'ow the respective LLD. Tritium was detected in the first quarter of 1991 at a concentration of 260 pCl/l (DWE 5, an indicator station). 26
Tritium is man made and cosmogenically produced and levels detected during 1991 are consistent with the pre operational program and the previous five years of operation. Specifically, the pre operational survey indicates that tritium activity ranged between 60 and 220 pCl/l with an average of 136 pCl/l. Similarly, the range indicated during the previous five years of operation was from 170 to 545 pCl/l with an average activity of 265 pCl/l. 3.3.2 Groundwater _ Four groundwater samples were collected from one sampling location, GWK 1, and analyzed for tritium and Gamma emitters were not detected; however, gamma emitters. 4 tritium was detected in two of the four samples at concentrations of 200 and 340 pCl/l. Tritium is man made and cosmogenically produced and levels detected during 1991 are consistent with the pre operational program and the previous five years of operation. Spec;fically, the pre operational survey indicates that tritium activity ranged between 50 and 180 pCl/l with an average activity of 121 pCl/l. Similarly, the range indicated during the previous five years of operation was from 249 to 650 pCl/l with an average activity of 336 pCl/l. Although the concentrations detected in 1991 are slightly higher than the pre operational data, they are within the same range as those reported during the previous five years and well below the reporting levels and LLD (2000 pCl/l) required by the Waterford 3 ODCM. 3.3.3 Shoreline Sediment Four shoreline soil samples were collected from the following sampling locations: two samples from tne Mississippi River - shoreline downriver of the plant the shoreline of a drainage cana(SHWE 3) and two samples from l (SH'NK 1). Naturally occurring radionuc' ides including potassium-40, radium-226, and actinium 228 were detected in ali of the sarnples. Ceslum 137, a man-made nuclide was detected in samples from station SHWK 1 ano SHWE at concentrations of 49 and 32 pCi/kg(dry) respectively. No other man-made radionuclides were detected in any of the samples. i The cesium 137 results obtained during 1991 are consistent with those from the pre-operational program and the previous five years of operation. Specifically, the pre-operational survey indicates that cesium-137 was detected in 13 of 18 soil samples at concentrations ranging between 30 and 890 pCi/kg(dry) with an average concentration 01138 pCi/kg(dly). Similarly, the range indicated 27 L ,...._,_m.... ,-,m. ..,._,,_.,,.,-....r._-,
during the previous five years of operation was from 21 to 142 pCl/kg (dry) with an average activity 0151 pCl/kg (dry) respectively. Further, studies in Louisiana indicate that cesium 137 is commonly found in soils and sediments as a result of atmospheric weapon testing. Because the cesium 137 levels are - consistent with pre operational values and cesium 137 has been shown to be present in most Louisiana soils, these cesium 137 levels are more than likely attributable to weapon testing fallout. 3.4 Innestion Exoosure Pathwa.y 3.4.1-Milk Fo:ty eight milk samples were collected from two sampling locations and analyzed by gamma spectroscopy. Naturally occurring potassium 40 was detected in all samples and cesium-137 was detected in two samples (MKE-45 9/3 and 11/18) at levels of 3 and 4 pCl/l respectively from the control location. The i samples were also analyzed by a radiochemical procedure for iodine 131. Results from these analyses indicate that no activity was detected above the calculated LLD for iodine 131. The cesk.m ;37 results obtained during 1991 are consistent with those from the pre operational survey and the previous five years of operation. Specifica!!y, the pre-operational survey indicates that cesium 137 activity ranged between 3 and 7 pCi/l with an average activity of 4.8 pCl/l. Ceslum 137 was detected in 1986 at 4 pCi/l. 3.4.2 Fish Twenty fish samples, ten upstream and ten downstream of the plant were collected and the edible portions analyzed by gamma spectroscopy. Only naturally occurring potassium-40 was detected above the lower limits of detection in any samples. 3.4.3 Broad Lepf Veg_etation Thirty six broad led vegetation samples were collected and i analyzed by gamma spectroscopy and a radiochemical procedure for iodine-131. Naturally occurring radionuclides were detected in all of the samples; however,- no man made radionuclides were ~ detected above their lower limits of detection. 3.4.4 Food Products Three food products samples were collected and analyzed by a radiochemical procedure for lodine 131. Results indicated iodine-131 concentrations to be below the lower limit of detection. 28 r e-- ,,-m 4--.-- .-,-.,,,.,,--..-,m,._'-.,.m..- -.,;_,--.mm_-m._,-,.w,, ,_,vm-, ,,rm ~ y,, -~ve-r, ~- ,m.,-.
Further, the samples were analyzed by gamma spectroscopy. Natura:ly occurring potassium 40 was the only radionuclido detected in all the samples. All man made garnma emitters were below their respective lower limits of detection. 3.5 . Statistical Analyses 3.5.1 Calculation of the Mean and Standard Deviation The mean and standard deviation for differont groups of analyses are calculated using the following equations-(F1) 2= n f 30.6 E X' - (n) (X): (F2) g, s.t (n-1) j x = mean of sample population, s = standard deviation of sample population, n = number of samples in sample population, and x, = value of the l'th sample. 3.5.2 Comparing Two Sample Population Means The meant of two sample populations are compared for statistical difference ising the standard 't" test. The use of the test requires the assum,Lon that the data within the populations are normally distributed and that the true standard de.vlations of the mean are equal for both populations. The standard "t" test tests the hypothesis that the true means of both populations are equal. The 't" value can be calculated from the equation below (obtained from the CRC Standard Mathematical Tables,26th Edition (1981)): (R-T') f, (F-3) '(n,-1)s,' + (n -1) s[" 'y y*5 y where: A"

The T value can be calculated from the following equation (obtained from the CRC Standard Mainematical Tables, 26th Edition (1981)): (F-4) I = -- (n)" where: 'd = the average of the difference between the correlated data points from the two sample populations: d = f 'UY lol x, = the l'th data point from population y, y, = the l'th data point from population y, N = the number of correlated pairs of data points, n = degrees of freedom, for equation F 4, n=N 1, and s,= the standard deviation of the difference between the i correlated data points. The calculated "t" value in both cases is used to test the hypothesis that the true mean of the first population ,) is equal to the true mean of the second population (p ) assu(ming that the true standard deviations of both populations are equal ( y The calculated "t" value is compared to a tabular T value such,). ,=p that:

A statistical analysis using the standard "t' test (described above) was performed comparing the a<erage exposure rates from 0 2 miles and 2 5 miles to the average exposure rate at >5 miles, in short, the results of the analyses show the average expost:re rate at 0 2 miles to be statistically lower than at >5 miles and the average exposure rate at 2 5 miles to be statistically the same as at >5 miles. Table 3.2 )ummarizes the results of this analysis. 3.5.4 Gross Beta Activity on Air Particulate Filters Additionally, the standard 't" test was used to compare average gross beta activity from each indicator station to the average gross beta activity at the control station. The results from this test show average activity detected at all indicator locations to be statistically the same as the activity detected at the control location. Table 3.3 summarizes the result of this analysis. 3.5.5 Gross Beta Activity in Monthly Drinking Water Composites FinaBy, the standard "t* test was used to compare average gross beta activity from the two indicator stations to the average gross beta activity from the control station. The results from this test show average activity detected at both indicator locationt to be statistically the same as the average activity detected at the control location. Table 3.4 summarizes the result of this analysis. 3.6 Deviations from the REMP 3.6.1 Unavailable Samoles Deviations from the REMP associated with missing TLDs resulted from theft of the dosimeters and were beyond the control of Waterford 3. Three TLDs were discovered missing from locations A 2, D 5, and R-6 during dosimeter change out at the end of the third quarter. Consequently, the missing TLDs were replaced and the deviation noted. Milk samples were not available during 1991 from the animal owners at station MKO 1 since the cows are not currently producing milk for human consumption. With the absence of milk samples at these stations, broad leaf vegetation sampling was performed. 31
~._ _.____ _ i Mechanical malfunction of a sample pump resulted in low sample volume for one air sample. Although the sample volume was sufficient to complete analysis, the requirement for continuous sampling was not met for this sample period. A routine sampler maintenance schedule is currently in effect to reduce instances of malfunction. Additionally, three water samples failed to meet requirements for sample continuity. Tubing problems were responsible for two of the failures, while the third was a result of a power failure at the sample site. As a result, the routine maintenance schedule will be modified to address sampler tubing problems. Sample volumes in all instances were sufficient to complete analysis. A list of deviations and associated explanations is provided in Table 3.5. 3.6.2 Missed Lower Umits of Detection All lower limit of detection requirements were met for 1991. 3.7 Annual Land Use Census in compliance with Waterford 3 ODCM, the annualland use census was conducted on October 1 and 2,1991. The nearest residence, garden, and milking animalin each sector within a five mile radius of the plant were located by visual inspection and verbal inquiry. Although residence and garden locations remained unchanged from the 1990 census, three new milk goat locations were identified. Upon inquiry, It was discovered that the animals are not currently producing mi:k for human consumption. The results of the 1991 census are summarized in Table 3.6. l 32

S-The radiological environmental data collected during 1991 are consisterv. with the data obtained during the previous five years of plant operation (1986 90), the Pre-operational Environmental Radic.:ogical Surveillance (PERS) Program, and the first two years of the REMP prior to Waterford 3 initial crhicality (1983 84). The only man-made radionuclides detected in the environmental samp!es analyzed during 1991 were ceslum 137, and tritium. Ceslum 137 was detected in two milk and shoreline soil samples. Studies in Loulslana indicate that cesium 137 is commonly found in so!!s and sediments as a result of weapons testing. Further, the detected activity in allinstances was at levels less than the required lower limit of detection and well below levels requiring notification. In addition, the detected concentrations were consistent with pre-operational levels. Therefore, it is unlikely that the presence of cesium in these samples can be attributed to Waterford 3 operation. Tritium was detected in one drinking / surface water samp!e at levels below the . required lower limit of detection and well below levels requiring notification. Tntium is man made and cosmogenically produced and was frequently detected in samples taken prior to Waterford 3 operation. Due to the absence of tritium in drinking / surface water samples located at a closer downstream location and the presence of tritium in pre operational samples at comparable levels, it is not likely that the tritium detected in the drinking water samples in 1991 was a result of plant operation. Tritium activity in the groundwater samples was slightly higher than pre-operationallevels.but consistent wit" levels detected during the previous five years of operation. Additionally, the high statistical errors associated with the indicated concentrations are higher than would be expected with true activity. Further, the amounts released were well below regulatory limits, and the concentrations detected in the groundwater were well below both the required LLD and the reporting level. In conclusion, based on the evaluation of the REMP data collected during 1991 the operation of Waterford 3 had no discernable radiologk alimpact on the environment. 39

- 1 A new efficiency curve was constructed using a blank EPA plastic air filter.
Efficiencies calculated using this air filter geometry were approximately 30s hicher than previous geometries using air particulate filters.
- 2 Blind water samples contain several isotopes which have different beta energies.
The efficiency curve for beta in water was constructed using Cs-137. Because the strontium isotopes have different beta energies than Cs-137, the results may not always agree with the standard beta in water efficiency using only Cs-137. ,3 The results submitted by System Chemistry for Total Potassium (K) were less thnn the lower control unit established by EPA for this sample. System Chemistry will investigate possible sources ef error within the gamma spectrometer efficiency curves and the calculations used to convert K-40 measurements into Total Potassium results. The results of these investigations will be included in the next monthly report. It should be noted that the mean result submitted by 63 laboratories whose results were included in the Grand Average was 1.5 standard deviations below the value used by the EPA as the "known value" for Total Potassium for this cross-check sample. Of the results classified as outside the control limits by EPA, 17 were outside of the lower control lbmit set by the EPA while only 3 results were outside of the higher co: rol limit. The submitted results were drastically shifted below the EPA established "known value". A request will be made to EPA to recheck the published "known value" for Total Potassium of this sample. Results of this inquiry will be included in the next monthly report after receipt of a reply from the EPA. The U.S. EPA was contacted and confirmed that the "known value" for Total Potassium was correct. An independent experiment was developed to measure Total Potassium using a known mass on Potassium Nitrate dissolved in 3.5L of water. The experimented value was calculated to be 0.993 of the theoretical value. l 103

D 1.0 ANALYSIS OF SAMPLES FOR GROSS BETA ACTIVITY D-1.1 Air Particulates After allowing for the radon 222 and radon-220 daughter products to decay, the particulate filters were counted in a gas-flow proportional counter. D-1.2 WateI A known volume of water, usually 200 milliliters, was reduced by evaporation, transferred to a two inch diameter planchet, and evaporated to dryness. The planchet was counted for 100 minutes in an automatic alpha-beta counter. D-2.0 ANALYSIS OF WATER SAMPLES FOR TRITIUM A known volume of water,5 milliliters, was added to 15 milliliters of liquid scintillation solution in a 25 milliliter vial. The sample was counted for 500 minutes in a liquid scintillation counter. D-3.0 ANALYSIS 7F SAMPLES FOR IODINE-131 D-3.1 Milk and Water Up to four liters of sample were mixed with a stable iodine carrier solution and eluded through an anion exchange resin column to remove iodine from the sample. The iodine was stripped from the resin with sodium hypochlorite colution, reduced with hydroxylamine hydrochloride, and extracted into carbon tetrachloride as free iodine. It was back-extracted as iodide into sodium bisulfite solution ano precipitated as palladium iodide. The precipitate, palladium iodide, was weighed for chemical yield and mounted on a nylon planchet level beta analysis. The chemical yield was corrected by measuring the stable iodide conter.t of the milk or water with a specific ion electrode. D-3.2 Broad Leaf Veoetation lodine analysis was performed using gamma spectroscopy. The time between sample receipt and analysis, the sample size and count times were adjusted in order to attain the required lower limit of c tection. Refer to Section E-4.2 for a description of gamma spectroscopy procedure. 105 l
D-4.0 GAMMA SPECTROSCOPY ANALYSIS I I Air particulate filters and iodine cartridges, water, milk, broadleaf vegetation, sediment, food products and fish samples are analyzed by gamma spectroscopy. Initially, the samples are prepared in containers, using the appropriate geometry for its sample type. Secondly, the sample is counted in a shielded high purity germanium (HPGE) or germanium lithium (GeLi) detector coupled to a computer based data acquisition system that performs pulse height analysis. The computer software program defines peaks by changes in the slope of the spectrum. Additionally, after comparing each specific peak energy with - a library of peaks for isotopic identification the program performs the radioactivity calculation using the appropriate fractional gamma ray abundance, half life, detector efficiency. and net counts in the peak region. D 5.0 ENVIRONMENTAL DOSIMETRY Thermoluminescent Dosimeters (TLDs) manufactured by Panasonic (model UD-814AO) were used for environmental dosimetry. Although the Panasonic TLDs contain one lithium borate and three calcium sulfate phosphor elements, only the calcium sulfate phosphor elements were used. For placement in field, two annealed dosimeters are placed inside a plastic bag and mounted in an aluminum frame. The dosimeters are checked monthly and exchanged for analysis each quarter using an automatic TLD reader manufactured by Panasonic (Model UD 710). 106 _--}}
