- 1. INTRODUCTION The Radiological Environmental Monitoring Program for the Comanche Peak Steam Electric Station was conducted under contract with T U Electric.
This report covers the period from January 1,1988 through December 31, 1988 and summarizes the results of measurements and analyses of data obtained from samples collected during this interval. 1 A. Site and Station Description Comanche Peak Steam Electric Station consists of two PWR units, each I designed to operate at a power level of about 1150 megawatts (electrical). l The station is located on Squaw Creek Reservoir in Somervell County about 40 j miles southwest of Fort Worth, Texas. The plant is currently under con. 1 struction with an anticipated Unit 1 fuel load date of late 1989. B. Objectives and Overview of the CPSES Monitoring Program United States Nuclear Regulatory Commission (USNRC) regulations require that nuclear power plants be designed, constructed, and operated to keep levels of radioactive material in effluents to unrestricted areas as low as reasonably achievable (ALARA) (10 CFR 50.34). To assure that these criteria are met, each license authorizing reactor operation includes technical specifications (10 CFR 50.36a) governing the release of radioactive effluents. In-plant monitoring will be used to assure that these predetermined release limits are not exceedeo. However, as a precaution against unexpected and undefined processes which might allow undue accumulation of radioactivity in any sector of man's environment, a program for monitoring the plant l environs is also included. 1 3
I T I ) 1 I Sampling locations were selected on the basis of local ecology, meter-l ology, physical characteristics of the region, and demographic and land use features of the site vicinity. The preoperational program was designed on the basis of the USNRC Branch Technical Position on radiological environ. mental monitoring issued by the Radiological Assessment Branch, Revision 1 (November 1979)(1), the proposed CPSES Technical Specifications, and the i proposed CPSES Offsite Dose Calculation Manuai (ODCM). In 1988 the radiological monitoring program included the measurement of ambient gamma radiation by thermoluminescent dosimetry; the determination of gamma mitters in vegetation, sediment and fish; the determination of air-borne gross beta, gamma emitters, and iodine-131; the measurement of tritium and gamma emitters in surf ace water; the measurement of gross beta, tritium and gamma emitters in ground water; the measurement of gross beta, tritium, 1-131 and gamma snitters in drinking water; and the determination of gamma emitters and 1-131 in milk.

Tb LSCTTOPES I The regulations governing the cuantities of radioactivity in reactor effluents allow nuclear power pl ants to contribute, at most, only a few percent increase above normal background radioactivity. Background levels at l any one location are not constant but vary with time as they are influenced by external events such as cosmic ray bombardment, weapons test f allout, and seasonal variations. These levels also can vary spatially within relatively short distances reflecting variations in geological composition. Because of I these spatial and temporal variations, the radiological surveys of the plant environs are divided into preoperational and operational phases. The pre-operational phase of the program of sampling and measuring radioactivity in various media permits a general characterization of the radiation levels and concentrations prevailing prior to plant operation along with an indica-tion of the degree of natural variation to be expected. The operational phase of the program obtains data which, when considered 41ong with the data obtained in the preoperational phase, assist in the evaluation of the radio-l logical impact of plant operation, implementation of the preoperational monitoring program fulfills the following objectives:
- 1. Evaluation of procedures, equipment and techniaues.
- 2. Identification of potentially important pathways to be monitored after the plant is in operation.
- 3. Measurement of background levels and their variations along poten-tially important pathways in the area surrounding the plant.
4 Provision of baseline data for statistical comparison with future operational analytical results. l l 4

!!. PROGRAM DESCRIPTION Seventy-eight (78) locations within a radius of 15 miles from the CPSES site were included in the monitoring program for 1988. The number and location of monitoring points were detennined by considering the locations where the highest of f-site environmental concentrations have been predicted frcrn plant effluent source terms, site hydrology, and site meterological conditions. Other f actors considered were applicable regulations, population distribution, ease of access to sampling stations, availability of samples at desired locations, secLrity and future progran integrity.
The preoperational environnental radiological progran for Comanche Peak is summarized in Table 1. Figures 1 and 2 show the locations of the various sampling points.
!!!. SAMPLING METHODS AND PROCEDURES To derive meaningful and useful data from the Radiological Environmental Monitoring Progran, sampling methods and procedures are required which will provide samples representative of potential pathways of the area. During the preoperational phase of the program, samples are collected and analyzed not only to obtain background radiological levels, but at the same time to acquire experience with the sampling methodology and procedural format dictated by site specific requirenents.
A. Direct Radiation Thennoluminescent dosimeters (TLDs) were used to determine the direct (ambient) radiation levels at monitoring points. Sampling locations were chosen according to the criteria given in the USNRC Branch Technical Position on Radiological Monitoring (Revision 1, November 1979),(1) The area around the station was divided into 16 radial sectors of 221/2 degrees each. TLDs were placed in all sectors. TLDs were located in two rings around the station. An inner ring was located at the site boundary and an outer ring I
I Y ISOTOPES was located at a distance of 4 to 6 miles from the station. Eleven sadt-tional TLDS were located at points of special interest, including two control locations. For routine TLD measurement s, two dosimeters of CaSO 4 :Dy in teflon cards were deployed at each selected 4 cation. One set of dosimeters was exchanged on a Quarterly basis and the second set was exchanged on an annual basis. Additional sets of dosimeters were shipped with each exchange cycle to serve as in-transit controls. For routine exchanges, TLDs were shipped by Federal Express. Individual dosimeters were calibrated by, exposure to an accurately known radiation field from a calibrated Cs-137 source. B. Air Particulates/ Air lodine Air particulate and air iodine samples were collected f rom the 13 locations described in Table 1. During the course of the year, several changes were made to air sampling locations as a result of changes to the draf t CPSES Offsite Dose Calculation Manual (ODCM) . The changes are in-dicated in the notations to Tables 2 and 3. By year end, the air sampling locations corresponded to the eight sampling locations required by the ODCM. All other locations were deleted. I Each air particulate sample was collected by drawing air through a 47-millimeter disneter glass fiber filter. Air iodine was collected by drawing air through a TEDA impregnated charcoal cartridge /(Scott N0 605018-
- 03) which was connected in series behind the filter. The filters and char-coal cartridges were collected weekly by CPSES staff. In the laboratory, air particulate filters were analyzed for gross beta activity and were composited quarterly for analysis by gamma spectrometry. Charcoal cartridges were l analyzed for iodine-131.

Yb ISOTOPES I C. Milk l Milk samples were collected by CPSES staf f monthly except for May through October chen samples were collected bimonthly. There were two principal milk s ampl ' .M locations; one indicator location, SSE-2.2 and one control location, Sh '.',5 Upon arrival at the laboratory, the milk samples ,I were promptly analyzed for 1-131 and by gamma spectrometry. D. Water The CPSES staff collect;d water from 12 locations. Sui f ace water was i collected at four loc 6tions (N 19.3, Est-1.4, N-1.5 and NE-7.4). Surface-drinking water was collected at two locations (N-9.9 and NNW-0.1). Location N-1.5 provides samples representative of Squaw Creek Reservoir surf ace water at a location beyond significant influence of the plant discharge. Location ESE-1.4 provides samples representative of discharges from Souaw Creek Reservoir, both down Squaw Creek ano to Lake Granbury via the return line. Location N-7.4 provides samples of Lakt Granbury surf ace water down stream of the discharge of the return line from Scuaw Creek Reservoir. There are six ground and drinking water locations (N-10.0, SSE-4.6, $ W-1.2, WSW-0.1, N-1.45 and N-9.8. Samples were collected from station N-10.0 during January and February only. Station N-9.8 replaced N-10.0. All samples were shipped back to the laboratory and analyzed by gamma spectrometry and composited by location quarterly for tritium analysis. The ground and drinking water samples were also analyzed monthly for gross beta, gamma isotopic and bi-monthly for iodine-131. E. Fish Twenty fish samples were collected at two locations for the 1988 pro-gram. An area 2.0 miles east-northeast of the site in Squaw Creek Reservoir was chosen as the indicator location, and a location at Lake Granbury was I e
I Y l Fish i,ampling was conducted in May and October chosen as a control location. at both locations. Fish were collected by CPSES staff. Available edible species were gutted at the time of collection. Samples were then frozen and shipped to the laboratory for analysis. Fish were filleted in the laboratory and the edible portion analyzed by gamma spectrometry. F. Shoreline Sediment Shoreline sediment samples were collected in February and August from Squaw Creek Reservoir, the indicator location. This is in an area of l potential recreational usage,1.0 mile north-northeast of the station. Samples were also collected from Lake Granbury, the control location, on the same days. Samples were also collected from Lake Grenbury downstream of the discharge of the return line from Squaw Creek Reservior on the same I dates. CPSES staff collected the tediment samples and shipped them to the laboratory for analysis by gamma spectrometry. G. Vegetables and Broadleaf Vegetation During the period June through November, sixteen samples were collected from three sampling locations. Food products were collected from a control (13.5 miles southwest) and two indicator stations. A total of twelve dif-ferent types of food product were collected during this sampling period.

SUMMARY
AND DISCUSSION OF 1988 ANALYT! CAL RESULTS Data from the radiological analyses of environmental media collected during the report period are tabulated and discussed below. The procedures and specifications followed in the laboratories for these analyses are as required in the Teledyne isotopes Quality Assurance manual, TWL-0032-395 and are detailed in Teledyne Isotopes Analytical Procedures manual. Radiological analyses of environmental media characteristically approach end frequently f all below the detection limits of state-of-the-art measure-ment methods.(2) The use of "<" in the data tables spbolizes that the result is less than the lower limit of detection (LLD) as defined in Appendix B. "ND" (Not Detected) is used periodically in the tables presenting gamma analysis results for various media. It primarily appears under the "Others" column, and indicates that no other detectable gamma emitting nuclides were identified. The Teledyne Isotopes analytical methods meet the LLD require-ments addressed in the draft CPSES Technical Specifications. Tables 2 through 16 give the radioanalytical results for individual samples. A statistical sumary of the results appears in Table 22. The reported averages are based only on concentrations above the limit of detec-tion. In Table 22, the fraction (f) of the total number of analyses which were detectable follows in parentheses. Also given in parentheses are the minimum and maximum values of detectable activity during the report period. I 11
I WTri prWNE ISOTOPES I A. Direct Radiation Environment al r adi ation dose rates determined by thermoluminescent dosimeters (TL0s) are given in Table 2. TLD badges of four readout areas each were deployed at each location on quarterly and annual cycles. The mean values of four readings (corrected individually for response to a known dose and for in-transit exposure) are reported. A statistical summary of the 1988 data ,is included in Table 22. Indi-vidual measurements of 210 external radiation levels in the environs of the CoSES site ranged from 0.13 to 0.20 mR/ day during 1988. For the quarterly analyses the average activity of the control locations was 0.16 mR/ day with a range of 0.14 to 0.18 mR/ day. The average of the indicator locations for the quarterly saples was 0.16 mR/ day with a range of 0.10 to 0.20 mR/ day. For the annual suples: The activity for the control sample was 0.15 mR/ day. The control sample from station WSW-7 was destroyed by the Highway Depart-ment.- The indicator locations had an average of 0.15 mR/ day with a range of 0.12 to 0.18 mR/ day. Oakley(3) calculates an ionizing radiation dose equivalent of 82.2 I mR/ year for Fort Worth including a terrestrial component of 45.6 mR/ year and an ionizing cosmic ray component of 36.6 mR/ year (excludes neutron compo-nent). Since Oakley's values represent averages covering wide geographical areas, the measured ambient radiation average of 58 mR/ year for the immediate locale of CPSES is not inconsistent with Oakley's observations. Significant variations occur between geographical areas as a result of geological com-position and altitude differences. Temporal variations result from changes in cosmic ray intensity, local human activities, and f actors such as ground cover and soil moisture. I 12
T N g B. Air Particulates/ Air Iodine A total of 571 charcoal cartridges were analyzed for airborne iodine-131 by gamma spectrometry. No iodine-131 was detected at any of the sampling stations. Results of these measurements are presented in Table 3. A total of 570 air particulate filters were collected and analyzed for gross beta activity. For the year of 1988 the average gross beta activity for the control location was 0.025,pC1/m3 with a range from 0.009 I to 0.047 pC1/m3 For the eleven indicator locations the yearly average was 0.023 pCi/m3 with a range from 0.007 to 0.050 pCi/m3 Air filters were composited quarterly and then analyzed by gamma spectrometry. The gamma spectrometry data is presented in Table 5. Cosmogenic beryllium-7 was detected in all 47 samples while potassium 40, a naturally occurring nuclide, was measured in five samples. The average beryllium-7 activity for the control location was 0.09 pC1/m3 with a range of 0.074 to 0.110 pC1/m3 For the indicator locations, the average
- beryllium-7 activity was 0.091 pCi/m3 with a range of 0.060 to 0.137 pCi/m3 Naturally occurring potassium-40 was detected at one control location samples with an activity of 0.007 pC1/m3 The average potassium-40 activity for the indicator locations was 0.01 pCi/m3 with a range of 0.007 to 0.014 pCi/m3, C. Milk There were a total of 38 milk samples collected in 1988; 19 from the indicator location and 19 from the control location. All samples were analyzed for iodine-131 by radiochemistry and for other gamma-emitting isotopes by gamma spectrometry.

l TE L mrmss I No iodine-131 was found in any of the milk samples. The lower limits of detection can be found in Table 6. Results of the gamma spectrometry measurements are presented in Table 7. Naturally occurring potassium-40 was detected in all of the milk s ampl es . The average activity for the control location was 1391 pCi/l with a range of 1180 to 1520 pCi/1. For the indicator location the average activity was 1341 pCi/l with a range of 1060 to 1490 pCi/1, Cesium-137 was not detected in any of the samples, , D. Water l Ground and drinking water samples were collected from six locations during 1988; however, only two samples (Janu ary and February) were col-lected from station N.10.0. Location N-10.0 was moved to N-9.8 so that the actual groundwater input into the Granbury city water supply would be sam-pled. The samples were analyzed monthly for gross beta activity and gamma spectrometry. The gamma spectrometry analysis showed no detectable activity above the LLO for all samples. The samples were also analyzed for iodine-131 bi-monthly with no measurable activity. Quarterly composites for each sampling location were analyzed for tritium. No tritium was detected. Of I the 67 ground and drinking water samples analyzed for gross beta, 45 indicator locations had measurable activity with an average of 8.4 pCi/l and a range of 1.2 to 15 pCi/1. Fif teen out of 15 control samples had measurable gross beta activity with an average of 3.6 and a range of 2.3 to 4.5 pCi/1. Results of these analyses are contained in Table 8, 9,10 and 11 respec-tively. Surf ace water was sampled from four locations during 1988. Fifty-two samples were analyzed by gamma spectrometry. No radioactivity was detected above the lower level of detection. Fif ty-two samples were 14
T l analyzed for iodine-131, all were below the lower limit of detection. Sixteen composited surf ace water samples were analyzed for tritium and all were below the lower level of detection. Results are presented in Tables 16, 17 and 18 respectively. Surf ace water-drinking was collected from two stations. All sampl es were analyzed for gamma; all were below the lower limit of detection. Twenty-six samples were analyzed for gross beta, the indicator station had an average activity of 18 pCi/l with a range of, 8.3 to 27 pCi/1. The control I station had an average activity of 16 pCi/l with a range of 8.0 to 28 pCi/1. The quarterly composites for tritium were below the lower limit of detection. Iodine-131 analyses by radiochemistry were perfonned on 52 samples, of surf ace water-drinking. There was no meaue6Lle activity. Results of these analyses are contained in Tables 12-15. E. Fish The results of gamma spectrometric analyses of fish samples collected during 1988 are presented in Table 19. A total of twenty samples were l analyzed, nine from the indicator location ENE-2 and eleven from the control location ENE-8. Sampling efforts concentrated on the larger edible species of commercial and/or recreational importance. Cesium-137 was detected in three of the samples with an average activity of 16.9 pC1/kg wet and a range of 9.9 to 25.1 pCi/kg wet. l Naturally occurring potassium-40 was detected in all samples. average potassium-40 concentration for the nine indicator samples is 3394 The pC1/kg wet with a range of 2720 to 4790 pCi/kg wet. The average concen-tration for the control location is 2798 pCi/kg wet with a range of 2000 to 3580 pCi/kg wet. I . 15
m I TE M I F. Shoreline Sediments The processes by which radionuclides and stable elements are concen-trated in bottom sediments are complex, involving physi 7hemical interaction in the environment between the various organic and inorganic materials I from the watershed. These interactions can prcceed by a myriad of steps in which the elements are absorbed on or displaced from the surf aces of col-lodial particles enriched with chelating organic materials. Biological i action of bacteria and other benthic organitms also contribute to the con-centration of certain elements and in the acceleration of the sedimentation process. l Results of the gamma isotopic analyses of the sediments sampled from the CPSES environment are given in Table 20. For 1988 three locations, one l control and two indicators, were sampled semiannually. The average, fraction of detectables, and range of radionuclide concentrations are summarized in i Table 22. Gamma emitters found in detectable concentrations were K-40, Pb-212, I R a-226, Bi-214, Pb-214 and Th-228. G. Vegetation Results of gamma spectrometric analyses of vegetation samples are contained in Table 21. Potassium-40, a naturally occurring isotope, was found in 16 samples. The average potassium-40 activity for the control location was 3320 pC1/kg wet with a range of 2330 to 4620 pCi/kg wet. For the indicator locations the average potassium-40 activity was 3642 pCi/kg wet with a range of 990 to 7350 pCi/kg wet. Naturally occurring beryllium-7 was detected in one indicator sample with an activity of 125 pCl/kg wet. Cesium-137 was below the lower limit of detection in all samples. lI 16

V. CONCLUSICNS lt can be concluded from the levels and fluctuations of radioactivity obt ained in environment al samples during 1988, that sensitive indicators of radioactivity for the environment around the CPSES have been selected. The atmospheric environment was sampled for airborne particulate matter, radiciodine, and direct radiation. The terrestrial environment was sampled for milk, ground-drinking water, surf ace-drinking water and food products. The aquatic environment was sampled for surf ace water, fish and shoreline sediment. The analyses of these samples provided results which were either below the measurement detection limits or were indicative of natural ter-restrial and cosniic ray radiation levels. I I I I I I I I 18

I 'I US EPA CROSS CHECK PROGRAM 1988 Notes: (a) EPA Results Expected laboratory precision (1 sigma). Units are I pCi/ liter for total PCi for air particulate water, and milk except K is in mg/ liter. filters. Units are I (b) Teledyne Results and milk except K is in mg/ liter. particulate filters. Average i one sigma. Units are pCi/ liter for water Units are total pCi for air (c) Units for food analysis are pCi/kg except K 40 which is mg/kg. (d) The average result of 86 PCi/kg was lowered by one analysis of 80 l pCi/kg, in which 1 131 may have been lost in processing. If this analysis is discarded and the higher results of the other 2 aliquots are taken, the average becomes 94 pCi/kg which is more favorable ( 1.1 sigma for 2 determinations). Our investigation revealed no systemic I reason for the low 1 131 ( 2.77 sigma for 3 determinations). Our previous performance for this analysis shows no systematic bias. Moreover. (e) There is no apparent reason for the deviation. Although there is a bias high, the bias does not appear to be changing significantly. Starting with the 01/13/86 data, the ratio is the average TI results to the EPA result is 1.27, 1.10. 1.08 and 1.15. (f) The Ruthenium 106 results (as well as other isotopes in the EPA sample) for February 5, 1988 EPA sample were based on a new standard (Amersham) I used in the December 1987 annual calibrations. A calculation using the previous NBS standard efficiencies gave an average of 98.0 pC1/ liter having a normalized deviation of 1.15. A second Amersham standard in I a Marinelli was prepared and agreed with the NBS standard. These efficiencies are in use currently. The Cesium 134 results (as well as the other isotopes in the EPA I (g) sample) for February 5,1988 EPA sample were based on a new standard (Amersham) used in the December 1987 annual calibrations. A calculation using the previous NBS standard efficiencies gave an I: average of 60.2 pCi/ liter having a normalized deviation of 1.80. A second Amersham standard in a Marinelli was prepared and agreed with the NBS standard. These efficiencies are in use currently. (h) The samples were analyzed for Ra 228 by PRO 032 67. A new procedure (PRO 032 97) has betn formalized and is currently in use for all samples. The results using the new procedure gave 6.2 61.4 pCi/ liter. I (i) An investigation was conducted and there is no apparent reason for the deviation. The samples contained an unusually high concentration of l stable iodide (3.6 mg/ liter) as determined by electrode readings which was verified at that time. The chemical yields were properly calculated taking these reaoings into account. No corrective action is I necessary since these results fall within the EPA 3 sigma control limits and no trends on previous 1131 intercomparison results are evident. 62
I I l Notes: (Cont.) US EPA CROSS CHECK PROGRAM 1988 (j) Dr. Frank Novielli of the EPA states that the EPA takes energy Cor rection into account, He mailed us a document which indicates now this is achieved. Teledyne isotopes has implemented the EPA method for I energy correction. (k) High Concentration of CO*60 in the sample (50 001/I) resulted in f alse Or, Frank I beta counts on the Tennelec counters from Co 60 gamma. Norelli of the EPA stated that the LPA will discontinue using Co 60 in Performance Evaluation samples (effective October 1988) because of this problem. , (1) Low alpha caused by presence of chlorides in the sample residue which increases self absorption. Samples are now being evaporated with more These reported results I nitric acid to convert chlorides to nitrates. fall within the EPA 3 sigma control limits. The investigation revealed no apparent reason for the reported low I (m) value; the result is within the EPA 3 sigma acceptance region. The new rapid extraction method for Ra 228 has provided acceptable results for all of the last 7 EPA tests. (n) The deviation noted is due to unusually high self absorption characteristics of EPA water spikes. Our results and the midwest I laboratory, each independently calibrated with Am 241, obtained low results by the same margin. Corrective action involves applying the self absorption curve derived by our analysis of EPA water in 1976 Collaborative Study (solid line) instead of the usual curve (dashed I line) when calculating EPA cross check samples.

An experiment with direct ashing (EML method) and iI with ion exchange (EPA iiiathod) as alternatives to the TCA separation step is being explo"ed. This study includes an experiment in which 4 3 spiked milk samples are stored for several weeks before analysis in 5 order to determine whether radiostrontium becomes bound to the protein or fat components of the milk,

I I I ANALYSIS OF SAMPLES FOR !ODINE-131 I Milk or Water Two liters of sample are first equilibrated with stable iodide carrier. A batch treatment with anion exchange resin is used to remove iodine from the sample. The iodine is then stripped from the resin with sodium hypochlorite I solution, is reduced with hydroxylamine hydrochloride and is extracted into carbon tetrachloride as free iodine, it is then back-extracted as iodide into sodium bisulfite solution and is precipitated as palladium iodide. The precipitate is weinhed for chemical yield and is pounted on a nylon planchet I for low level beta counting. The chemical yield is corrected by measuring the stable iodide content of the milk or the water with a specific ton electrode.

' thermally induced signal loss (f ading), and negligible self dosing. The energy response curve (as well as all other features) satisfies NRC Reg Guide 4.13. Transit doses are accounted for by use of separate TL0s, Following the field exposure period the TL0s are placed in a Teledyne isotopes Model 8300. One fourth of the rectangular TLD is neated at a time and the I ,
measured light emission (luminescence) is recorded. The TLD is then annealed and exposed to a known Cs-137 dose; eacn area is then read again., This provides a calibration of each area of each TLD af ter every field use, The transit controls are read in the same manner, Calculations of results and the two sigma error in net milliRoetgen (mR): I RESULT = 0 = (Og+02 +0 3 +0 4 )/4 TWO SIGMA ERROR 1= 2((0 -0)2+(0 2

Each Ge(Li) detector is calibrated for both positions. The detection limit for I-131 of each charcoal cartridge can be determined (assum-ing no positive I-131) uniquely from the volume of air which passed through In the event I-131 is observed in the initial counting of a set, each it. charcoal cartridge is then counted separately, positioned on the face of the detector.

OETERMINATION OF GROSS ALPHA AND/0R GROSS BETA ACTIVITY IN WATER SAMPLES I
1.0 INTRODUCTION
The procedures described in this section are used to measure the overall radioactivity of water samples without, identifying the radioactive species present. No chemical separation techniques are involved. One liter of the sample is evaporated on a hot plate. Different volumes may be used if the suple has a significant salt content as measured by a conductivity meter, or if unusual sensitivity is desired. if requested by the customer, the sample is filtered through No. 54 filter paper before evaporation, removing particles greater than 30 microns in size. After evaporating to' a small volume in a beaker, the sample is rinsed into a 2-inch diameter stainless steel planchet which is stamped with a concentric ring pattern to distribute residue evenly. Final evaporation to dryness takes place under heat lamps. Samples which appear to be hygrosecpic are dried again under heat lamps just prior to counting. Residue mass is determined by weighing the planchet before - and af ter mounting the sample. The planchet is counted for alpha and/or beta activity on an automatic proportional counter. Results are calculated using ( empirical self-absorption curves which allow for the change in effective counting efficiency caused by the residue mass. I 73
I I I 2.0 DETECT 10,N CAPABILITY Detection capability depends upon the sample volume actually repre-sented on the planchet, the background and the efficiency of the counting instrument, and upon self-absorption of alpha and beta particles by the mounted sample. Because the radioactive species are not identified, no decay l , corrections are made and the reported activity < refers to the counting time. The minimum detectable level (MOL) for water samples is nominally 1.6 picoturies per liter for gross beta at the 4.66 sigma level (1.0 pCi/t at the 2.83 sigma level), assuming that I liter of sample is used and that 1/2 gram of sample residue is mounted on the planchet. These figures are based upon a nominal counting time of 50 minutes and upon representative values of counting efficiency and background of 0.2 and 1.2 cpm, respectively. The MDL for gross alpha - activity is nominally 2.3 picocuries per liter at the 4.66 sigma level (1.4 pCi/t at the 2.83 sigma level) also assuming that I liter of sample is used and that 1/2 gram of sample residue is mounted on the planchet. These figures are based upon a nomini 200 minute counting time and upon a representative efficiency of 0.02 arn a background of 0.1 cpm. The MOL becomes significantly lower as the mount weight decreases because of reduced self-absorption. At a zero mount weight, the 4.66 sigma MOL for gross beta is 0.9 picrocurit:s per liter and the MOL for gross alpha is 0.3 picocuries per liter. These values reflect a beta counting efficiency of 0.38 and an alpha counting efficiency of 0.18. I I < 74
