I. INTRODUCTION The preoperational radiological environmental monitoring program-
- (REMP) for Pennsylvania Power and Light Company (PP&L) at the Susquehanna ,
Steam Electric Station (SSES) was conducted from April 1972 to September 1982. On September 10, 1982, Unit #1 became critical, thereby initating the'.
l operational phase of the program. The preoperational phase of the program, as well as the initial phase of the operational program (September 10, 1982 through June 1983) was conducted by Radiation Management Corporation (RMC).
NUS Corporation conducted the REMP from June 1983 until August 1984 when [
i Teledyne Isotopes (TI) took over the operational-REMP. The analytical j program is now being conducted by Teledyne Isotopes under contract ~with
! Pennsylvania Power and Light Company. The sample collection portion of the program was conducted by Ichthyological Associates until June 1985 when l Ecology III assumed responsibility at the Susquehanna SES Biological Labora-
. tory essentially utilizing the same staff.
l This report covers the period January 02, 1985 through-January 07,-
1986. Teledyne Isotopes performed all the analyses including the Quality Control and the Quality Assurance Program. Data from programs conducted in -
prior years have been presented in a series of annual reports. (1-13, 21) l A. Site and Station Description Susquehanna SES contains 2 BWR generating units, each with a-capacity of about 1050 MWe. Unit'#1 achieved initial criticality on September 10, 1982. Unit #2 achieved initial criticality on May 8,--1984. The site'is located on an approximately 1300 acre tract along the Susquehanna River,-five miles northeast of Berwick in Salem Township, Luzerne County, Pennsylvania. -

- 8. Objectives and Overview of Susquehanna SES Monitoring Program i
United States Nuclear Regulatory Commission (USNRC) regulations require that nuclear power plants be designed, constructed, and operated to keep i
levels of radioactive material in effluents to unrestricted areas as low as
! reasonably achievable ( ALARA) (10 CFR 50.34 and 10 CFR 20.1c). To ensure that these criteria are met' each license authorizing reactor operation includes technical specifications (10CFR 50.36a) governing the release of 1
radioactive effluents.
In-plant monitoring will be used to ensure that these predetermined release limits are not exceeded. However, as a precaution against unexpected and undefined processes which might. allow undue accumulation of radioactivity i
in any sector of man's environment, a program for monitoring the plant environs is also included in the Susquehanna technical specifications. -
! ( ;
{ The ' regulations governing the quantities of radioactivity in reactor effluents allow nuclear power plants to contribute, at most, only a few percent increase above normal background radioactivity. Background levels at any one location are not constant but vary with time as they are influenced
~
4 by external events such as cosmic ray bombardment, weapons test' fallout, and '
1
. I-2 L .;
.L seasonal variations. These levels also can vary spatially within'relatively ,
short distances reflecting variations in geological composition and other l factors. Because of these spatial and temporal variations, the radiological i
surveys of the plant environs are divided into preoperational and operational ,
phases. The preoperational phase of the program of sampling and measuring radioactivity in various media permits a characterization of the radiation levels and concentrations prevailing prior to plant operation along with an s indication of the degree of natural variation to be expected. The opera-tional phase of the program obtains data which, when considered along with the data obtained in the preoperational phase, assist in the evaluation
\
of the radiological impact of plant operation.
The objectives of the operational Radiological Environmental Monitoring Program are: j
- 1. To identify, measure and evaluate existing radionuclides in the environs of the Susquehanna SES site and fluctuations in radioactivity levels which may occur. ,
- 2. To determine whether any significant increase occurs in the' -
concentration of radionuclides in critical pathways. ."e r .
- 3. To detect changes in ambient radiation levels. "
- 4. ,To verify that Susquehanna SES operations have no detrimental effects on the health and safety of the public or on the environment.
- 5. To fulfill the obligaties f the Radiological Environmental Monitoring section or nie t chnical specifications for Susquehanna SES.
Sampling locations were selected on the basis of local ecology, meteor-ology, physical characteristics of the region, and demographic and land use features of the site vicinity. The REMP was designed on the basis of the '

environmental monitoring as revised in Revision 1, November 1979.(17)
PP&L expanded the basic program to aid in the characterization of area radiation levels and Susquehanna SES impact.
In 1985 the radiological monitoring program included the measurement of ambient gamma radiation by thermoluminescent dosimetry;.the determination of gamma emitter.9, gross alpha, and gross beta in' shoreline sediments; the determination of gamma emitters and gross beta in fish; the determination of
,,,,,- gross beta, gross alpha,'and gamma emitters in airborne particulates; the measurement of airborne iodinc-131; the measurement of gross beta, gross alpha, gamma emitters, iodine-131, and tritium in water; the measurement of i -
k gross beta, gross alpha, gamma emitters, and tritium in precipitation; the measurement of iodine-131, gross beta minus potassium-40 and gamma emitters in cow milk and iodine-131 in goat milk; the determination of gamma emitters in game, poultry, eggs, and various fruits and vegetables; the determination of gamma emitters in algne; the determination of gamma emitters in pasture l
\
, grass; and, the determination of gamma emitters in soil and vegetation.

II. PROGRAM DESCRIPTION II. PROGRAM DESCRIPTION One-hundred and thirty-nine (139) locations were included in the Susquehanna SES monitoring program for 1985. Environmental sampling locations were divided into two classes, indicator and control. Indicator samples I
i are those collected at locations which are expected to manifest station effects, if any exist, and were selected on the basis of distance from the site, topography, hydrology, meteorology, demography, and drainage charac-teristica. Control samples are collected at locations which are believed will be unaffected by station operation. These provide a bacis on which to evaluate fluctuations in radioactivity at indicator locatiors in relation to natural phenomena and fallout. The number and locations of monitoring points were determined by considering the locations where the highest off-site environmental concentrations have been predicted from plant effluent source terms, site hydrology, and site meteorological conditions. Other factors considered were applicable regulations, population distribution, ease of access to sampling stations, security and future program integrity.
The operational environmental radiological program for Susquehanna SES is summarized in Table 1. Table 2 describes sample locations, associated
- media, and approximate distance and direction from the site. Figures 1 and 2 i
illustrate the locations of sampling stations relative to Susquehanna SES.
- In addition to the described analytical program, a milk animal, vege-table garden, and residence survey was performed in 1985. This survey located the nearest milk animal, garden and residence in each sector (out to 5 miles) and will be updated annually. These land use parameters are used in the assessment of potential radiological doses to individuals.and populations of the stated regions.

Sample locations and Media for the SSES Radiological Environmental Monitoring Program 1985 Location Codes:
The location codes are based on direction and distance from the site. The first two numbers represent each of the 16 angular sectors of 22-1/2 degrees centered about the reactor site. Sector one is divided evenly by the north axis and other sectors are numbered in a clockwise direction; i.e., 2=NNE, 3=NE, 4=ENE, etc. The next digit is a letter which represents the radial dis-tance from the station:

III. SAMPLING METHODS AND PROCEDURES To derive meaningful and useful data from the radiological environmental monitoring program, sampling methods and procedures are required which will i
provide samples representative of potential pathways of the area.
A. Direct Radiation i
Thermoluminescent dosimeters (TLDs) were used to determine the direct (ambient) radiation levels at seventy-three (73) monitoring points as j described in Tables 1 and 2. Sampling locations were chosen according to the criteria given in the USNRC Branch Technical Position on Radiological f Monitoring (Revision 1, November 1979).(17) 1 The area around the station was divided into 16 radial sectors of 22 1/2 degrees each. TLDs were placed in all sectors. The TLDs were placed at locations designed to take advantage of local meteorologic and topographic characteristics and population distribution characteristics. There were seven (7) control locations: 3G3, 3G4, 4G1, 7G1, 7H1, 12G1, and 12G4.
4 In 1985 direct radiation measurements were made using Panasonic UD-801 i
thermolumenscent dosimeters (TLDs) consisting of calcium sulfate doped with
)
i thulium (CaSO4:TM). The dosimeters were exchanged on a quarterly basis.
Element correction factors were determined for each dosimeter by exposure to an accurately known radiation field from a calibrated Cs-137 source.

I B. Surfacs Water i
i Surface water was sampled at nine locations from the Susquehanna River i
and other surrounding bodies of water. Time proportional automatic composite l
samples were collected monthly at 12H1 ' (Merck Company). Monthly samples
! were also composited from weekly grab samples at location 558 (under the power line) and location 655 (outfall area). Monthly grab samples were
-l collected at location 1D3 (Hocanequa Substation), location 12F1 -(Berw'ick 1
i Bridge), location 12G2 (between Bloomsburg and Berwick), and Lake Took-A-While (LTAW). Monthly surface water samples were analyzed for gross alpha, j gross beta, gamma emitters, iodine-131 and tritium. Stations SS8, 6S6 a
and 1D3, were the control stations.
2 Time proportional automatic composite water samplers were installed in i 1983 at the river water intake (6S6) and the cooling tower blowdown discharge "
line (657). These samples are collected at least weekly. Monthly composites
! of weekly samples were analyzed for gross alpha, gross beta,. iodine-131, I
, gamma emitters and tritium. Locations SS8 and 6S5 provide alternate data for 1
l locations 656 and 6S7, respecitvely, in the event that the automatic samplers i
malfunction.
2 C. Drinking Water Drinking water was sampled by means of a time proportional automatic composite sampler on a weekly basis from station 12H2 RAW. A~ daily grab -
sample was taken at 12H2 TREATED and composited into a weekly sample.
1 i
. These stations are located at the Danville Water Company (drinking i
i water supply closest to Susquehanna SES which could be affected by plant i discharge). 12H2 RAW is taken from the Susquehanna river intake structure j while 12H2 TREATED is drawn from the supply line after processing. Monthly >
composites of the 12H2 RAW and 12H2 TREATED samples were analyzed for gross-alpha, gross beta, gamma emitters, iodine-131 and tritium.

D. Algae l
l Susquehanna River algae collections were set up at six locations l
! beginning in May 1984 as a special study (not required by technical specifications) to locate the source of iodine-131 upstream of the Susquehanna SES as postulated earlier (11 ). Surface samplers were located i
above (AG-1) and below (AG-2) the Wilkes-Barre sewage treatment plant, above (AG-3) the Susquehanna SES river water intake structure, and below (AG-4)
< the cooling tower blowdown discharge diffuser. Bottom samplers were located above ( AG-5) the intake structure and below ( AG-6) the discharge diffuser.
I i
j Locations AG1, AG2, AG3 and AG5 serve as controls. for indicator locations AG4 and AG6. Dry monthly samples were analyzed by gamma spectrometry.

E. Fish Fish sampling was conducted in the spring (May) and the fall (October) at three locations for this program. Downstream of the Susquehanna SES on the Susquehanna River was selected as an indicator location (IND), and on upstream location was chosen as a control location (2H). Fish samples were also taken from Lake Took-A-While (LTAW), an indicator station.
Available edible species were filleted at the time of collection. The edible portsans were packed in dry ice and shipped to the laboratory for analysis by gamma spectrometry and for gross beta.
F. Shoreline Sediment Shoreline sediment (0 to 4 ft. of water) samples were collected in May and November at six locations in the Susquehanna River. These were Bell Bend (78), near Hess Island (11C), the old Berwick test track (12F), near Gould Island (28), between Shickshinny and the former State Hospital (2F) and Lake Took-A-While (LTAW). Samples were analyzed for gamma emitting nuclides, gross alpha and gross beta. The control locations are 2B and 2F.
G. Ground (Well) Water Eight wells: the Energy Information Center (256), the Riverlands Facility (3S5), the Peach Stand (452), the Training Center (4S4), the EOF Building (1155), the Serafin Farm (15A4), the Berwick Hospital (12EA) and the Berwick Water Company (12F3), a control station, were sampled monthly.
Gross alpha, gross beta, gamma and tritium analyses were performed on the monthly samples.
III-4
H. Airborne Particulates/ Air Iodine-131/ Precipitation Airborne patnways were examined by analyzing air particulates, air iodine and precipitation. Air particulates were collected on Gelman type-A/E, glass fiber filters with low-volume air samplers. Air iodine was collected 1
on one-inch-deep Science Applications, Inc. charcoal cartridges. Air sample volumes were measured with temperature-compensated dry-gas meters.
The samplers were run continuously and the filters and charcoal car-tridges exchanged weekly. The elapsed time of sampling was recorded on an elapsed-time meter. The initial and final volumes as registered on the dry gas meter, were recorded by the sample collector.
Atmospheric pathway samples were collected at eleven locations; the Information Center (2S2), the Biological Laboratory (SS4), the Colomb House (1152), the north transmission line (1554), the transmission 'ine east of route 11 (901), the Mocanaqua Substation (102), near Pond Hill (3D1), the Berwick Hospital (12E1), the Hazelton Chemistry Lab (7G1), at the Bloomsburg Service Center (12G1) and the PP&L roof in Allentown (7H1). The last three locations, 7G1, 12G1, and 7H1'were the controls. Air filters weru analyzed weekly for gross beta, then composited quarterly and analyzed for gross alpha and gamma emitters. Air iodine was collected on a charcoal cartridge in series with the air particulate filter at all locations. The charcoal cartridges are warranted to have an ef ficiency of removal of elemental iodine of 99". The charcoal cartridges were analyzed weekly for iodine-131.
Precipitation samples were collected at least monthly from locations 252, SS4, 1152, 1554, 981, 102, 3DI, 12E1, 7G1 (control) and 12G1 (control),
composited quarterly and analyzed for gross alpha, gross beta, tritium and gamma emitters.
III-5
I. Milk / Pasture Grass Cow milk samples were collected monthly from eight locations; 12B2, 12B3, 6C1, 1001, 1202, SE1, 13E3 and 10G1 (control). Samples were collected semi-monthly from April through October from locations 1282, SE1,13E3, and 10G1. Each monthly and semi-monthly sample was analyzed for gross beta minus potassium-40, iodine-131 and gamma emitters.
Goat milk sampling was scheduled at one location (8D1) on a quarterly basis. However, sampling was discontinued in May when goat milk was no longer available. Goat milk, if available, was analyzed for iodine-131 only.
f Pasture grass was collected monthly at the farm closest to the site (15A1). Pasture grass samples from location 801 were scheduled for collec-tion during quarters when the goat milk was unavailable. However, location 901 was discontinued in May when goat milk was no longer available. Each sample was analyzed by gamma spectrometry.
J. Vegetation, lop and Bottom Soil ihree samples, one vegetation, one top soil and one bottom soil were taken at ten stations: 254, 555, 1154, 1554, 9B2, 104, 302, 12E2 and 7G1, 12G3 (controls). These samples were taken in August by compositing twelve plugs at each location. The top soil consists of the first 2 inches of soil l
and the bottom soil is from the depth of 2 to 6 inches. All samples were analyzed for gamma emitting nuclides.
III-6
K. Food Products fruits and Vegetables Gamma spectrometry was used to analyze various types of food products collected from farms or gardens within the vicinity of Susquehanna SES.
These included the following: apples, honey, corn, cabbage, lettuce, potatoes, spinach, string beans, tomatoes, endive, red beets, and swiss chard. Indicator locations that were sampled were 1101, 7S5, 7B2, 1156 and 1281. The control location sampled was 2H1.
Meat Meat samples consisting of eqqu, chicken end duck were collected from local farms at indicator locations 12111 and IhD1. The edible portion was analyzed for gamma emitters.
4 Game Two deer samples and three composite squirrel sample 5were collected in the fall and the flesh was analyzed for gamma emitters. The deer samples were collected from indicator stations 3S and SS while the squirrel samples were collected from indicator stations 155, 1S and 2S.

SUMMARY
AND DISCUSSION OF 1985 ANALYTICAL RESULTS The analytical methods used by Teledyne Isotopes meet the lower limit of detection (LLD) requirements set forth in the Susquehanna Steam Electric Station Technical Specifications. The procedures, specifications and an explanation of the analytical calculation methods used in the laboratory for these analyses are summarized in Apendix B. Data from the radiological analyses of environmental media collected are tabulated and discussed below.
Radiological analyses of environmental media characteristically approach and frequently fall below the limits of state-of-the-art measurement methods.
(18) For the gamma spectrometric results listed in this report only those radionuclides positively detected are listed in the tables. A positively detected radionuclide is one in which the activity is greater than a critical value. The critical value is defined as LLD/2. (22) However, due to the presence of the natural Ra-226 and Th-228 decay chains in background gamma spectrometric results, the critical value for reporting Ra-226 and Th-228 is LLD. Typical LLD's of selected nuclides searched for by gamma spectrometry are listed in Table 19.
For analyses other than gamma spectrometry, "LT" is used in the data ,
i tables where activity was not positively detected. The use of "LT" in the {
data tables is the equivalent of the less than symbol (<). The number
[
following "LT" is a result of calculation as defined in Appendix B and Appendix C.

A. Direct Radiation Environmental radiation exposure rates determined by thermoluminescent dosimeters (TLD's) are given in Table 5. The mean quarterly value for each of 76 locations is reported in this table. (Due to the deviations and program changes there were 66 to 73 locations per quarter). A description of the TLD system used by PP&L is contained in Appendix B of this report.
1 A statistical summary of the .1985 data is included in Table 3. Indi-
! 5 vidual measurement of external radiation levels in the environs of the Susquehanna SES site ranged from 0.16 to 0.28 mR/ day. The average for all t
indicator locations, 0.20 +- 0.02 mR/ day, was virtually identical to the i
average for the control locations, 0.19 +- 0.03, and was also virtually
.idbntical, 0.20 +- 0.02, if the Allentown location was excluded from the
! control average.
Oakley (19) calculates an ionizing radiation dose equivalent of 82 mrem / year for the Wilkes-Barre area. Since Oakley's values represent averages covering wide geographical areas, the measured ambient radiation average of 73 mR/ year for the immediate locale of Susquehanna SES is consistent with Dakley's observations. Significant variations occur between geographical areas as a result of geological composition and altitude differences. Temporal variations result from changes in cosmic ray intensitty, local human activities and factors such as ground cover and soil moisture.

B. Surface Water Surface water was sampled from nine (9) locations including three control locations. Samples were analyzed for gross alpha, gross beta, iodine-131, tritium and gamma emitting radionuclides. The results are listed in Table 6.
Of the 83 indicator surface water samples analyzed, 9 had detectable .
gross alpha activity ranging from 1.3 to 2.4 pCi/ liter. Gross alpha was detected in 2 of 42 control samples at a concentration ranging from 1.1 to 1.9 pCi/ liter. These values are within the range for previously reported surface water samples.
A total of 125 surface water samples were analyzed for gross beta ,
activity. Groas beta was detected in 82 of 83 indicator locations at concen-trations ranging from 1.4 to 15 pCi/ liter. Of the 42 control surface water +
samples, 40 had detectable gross beta activity ranging from 1.4 to 6.7 pCi/ liter. These values are within the ranges reported in preoperational data.
A to' a1 of 125 surface water samples were analyzed for iodine-131. Of the 42 ce ntrol surface water samples analyzed, 5 had detectable activity, i ranging f rom 0.12 to 0.40 pCi/ liter. Of the 83 indicator surface water samples ar alyzed, 7 had detectable activity, ranging from 0.12 to 0.42 e
pCi/ liter.
The presence of iodine-131 in the control location samples, and the general distribution of the observed activities indicates that the presence of this isotope is not plant relsted. Similar activity lesels were reported in preoperational data. Alternatesourcesofconcentrationsinsurfacewater are medical uses in the area. '

The presence of increased tritium in the plant discharge line is att ributed to plant operations. The concentrations are well below U.S. NHC non-routine reporting limits. .The calculated dose to the maximally exposed individual is presented below in section IV-L.
All 125 surf ace water samples were analyzed for gamma emitting radio-nuclides. The results are presented in Table 6.
4 Using gamma spectrometry, naturally occurring potassium-40 was detected-in 15 of the 125 samples at concentrations ranging from 17 to 230
- pCi/ liter. Thorium-228 was detected in one sample with a concentration of 27 pCi/ liter. The man-made radionuclide cesium-137 was detected in 1 of 42 control samples at a concentration of 4 pCi/ liter. Cesium-137 was detected in 2 of 83 indicator samples at a mean. concentration of 4.6 pCi/ liter. The presence of Cs-137 in these samples is attributed to global fallout from previous atmospheric weapons testing..

The man made radionuclides of Cr-51, Mn-54, Co-60 and Zn-65 were detected in indicator surface water samples as follows: Chromium-51 was seen in one sample at a concentration of 98 pCi/ liter, manganese-54 was detected in two samples at a mean concentration of 4.6 pCi/ liter, cobalt-60 was identified twice at an average concentration of 4.3 pCi/ liter and Zn-65 i was detected once at a level of 4.6 pCi/ liter. All of these positive
, results were found at the 6S7 sample station. This station is the composite sampler located on the discharge line of Susquehanna SES. These positive 1
values are attributed to the operation of Susquehanna SES. The calculated dose to the maximally exposed individual is presented below in section IV-L.
i C. Drinking Water 1
A total of 26 drinking water samples were taken at the Danville Water Company (12H2). Drinking water for Danville is taken from the Susquehanna River and is the closest to Susquehanna SES which could be affected by plant discharge. These samples were analyzed for gross alpha, gross beta, iodine-131, tritium and gamma emitting radionuclides.
l The results are presented in Table 6. . As there are no public upstream
! drinking water facilities, the results of the analysis of the indicator drinking water should be compared to the control surface water samples.
The results of gross alpha and gross beta analyses are shown in Table
- 6. Alpha activity appeared in 4 of 26 samples with a mean of 1.2 pCi/ liter l and a range of 1.1 to 1.3 pCi/ liter. Positive beta activity was detected in l
l all of the samples with a mean concentration of 2.4 pC1/ liter and a range of i
1.5 to 3.4 pCi/ liter.
IV-5
Tritium was detected in 15 of 26 samples. The average concentration 4
was 102 pCi/ liter and the range was 59 to 150 pCi/ liter.
No iodine-131 was detected in any sample.
lhe results of the gamma spectrometry analysis are also shown in Table 6. Naturally occurring potassium-40 was detected in 4 of 26 samples with a range of 25 to 78 pCi/ liter The fallout radionuclide l
cesium-137 was detected once at a concentration of 2.9 pCi/ liter.
1 I Activity seen in drinking water was no different than those I l concentrations noted for the surface water control stations. Also, all concentrations are within the range of preoperational data.
There is no indication of the presence of any radionuclide in these drinking water samples attributed to the operation of Susquehanna SES. ;
D.' Algae i
A total of 32 algae samples were collected for analysis during the program year. Stations AG1, AG2, AG3 and AGS are upstream and are considered control stations for Susquehanna SES. AG4 and AG6 are indicator stations.
1 All samples were analyzed by gamma spectrometry. Results of gamma spectro-metric analyses of these samples are contained in Table 7.
, The naturally occurring radionuclide Radium-226 was found in 5 of .32 -
, samples. Thorium-228, a naturally occurring radioisotope, was found in 18 of 32 samples. The observed values for both Ra-226 and Th-228 were within the expected range of normal distribution.
1 IV-6 i
Cesium-137 was detected in 3 of the 19 control samples at an average activity of 0.22 pCi/g (dry). Cesium-137 was detected in 5 of 13 indicator samples at an average activity of 0.22 pCi/g (dry). Since it is present in global fallout, the occasional detection of cesium-137 in the environmental media is not unusual.
Indine-131 was found to be present in 11 of the 19 control samples and 5 of the 13 indicator stations with the average concentrations of 1.82 and 0.55 pCi/g (dry) respectively.
The presence of iodine-131 in the control locations and the general distribution of the observed activities indicates that the presence of this isotope is not plant related. Alternate sources of concentrations in algae are medical uses in the area. This data is consistent with iodine-131 levels which are reported in the surface water tablce of this report.
The man-made radioisotopes of Mn-54, Co-58 and Co-60 were detected in downstream algae samples. Manganese-54 was seen in 2 of 13 indicator samples at a concentration of 0.55 pCi/g (dry). Cobalt-58 was detected once at a level of 0.43 pCi/g (dry) and cobalt-60 was found in 2 of the 13 ,
t indicator samples at levels of 0.25 and 0.74 pCi/g (dry). These activities substantiate values already seen in surface water samples and are therefore attributed to the operation of SSES. The Mn-54 and Co-60 detected in the algae sample collected on 07/08/85 were also seen in the 657 composite water sample collected on the same day. The Co-58 detected in the algae, however, was not seen in the corresponding 657 composite water sample. The ratio of Co-58 to Co-60 (0.43/0.74) seen in the 07/08/85 algae sample was used to predict. the concentration of Co-58 used in the dose to man from water calculations presented below in section IV-L.

E. Fish Fish samples were collected during May and October from three locations.
Smallmouth 8 ass, Walleye and Channel Catfish were collected at both the indicator and control locations in May. White Sucker, Walleye and Channel Catfish were collected at both locations in October. In May and October Largemouth Bass and Channel Catfish were collecter, at Lake Took-A-While. A total of 17 samples were analyzed, 7 from the indicator location, 6 from the control location and 4 from Lake Took-A-While.
The results of gross beta analyses of fish samples collected during 1985 are presented in Table 8. All 17 samples had detectable gross beta activity ranging from 3.0 to 7.9 pCi/g (wet) with a mean for all stations of 6.0 pCi/g (wet). This is probably due to naturally occurring potassium-40 which is a beta emitter. The range of gross beta activity was not signif-icantly different from ranges reported during the previous year.
The results of gamma spectrometric analyses of fish samples collected during 1985 are presented in Table 8. As expected, naturally occurring K-40 was the major detectable activity in the edible portions of the fish and was found in all 17 samples. Cesium-137 was the only man-made isotope detected in fish. Cesium-137 was detected in 2 of the 6 control samples and ranged from 0.007 to 0.012 pCi/g (wet). Cesium-137 was also detected in one indicator sample at a level of 0.013 pC1/g (wet) and in one sample from Lake Took-A-While at a level of 0.009 pCi/g (wet). The Cs-137 concentrations are consistent with preoperatinal and control data and concentrations expected from atmospheric weapons testing.
There were no detectable levels of radioactivity in fish due to the operation of Susquehanna SES during the period of this report.

F. Shoreline Sediment Sediment samples were collected twice during this program year. Six locations were sampled, including three indicator, two control locations and Lake Took-A-While. All samples were analyzed by gamma spectrometry, gross.
alpha and gross beta. A statistical summary of the analytical'results including the average, fraction of detectables, and range of radionuclide concentrations is shown in Table 3, section IX.
i The results of the analysis of sediment samples for gross alpha activity are listed in Table 9. Detectable activity was observed in 8 of 11 samples 4
- from the indicator locations. The range of observed activity was 5.6 to 17 pCi/g (dry). Detectable activity was observed in all four samples from the control locaticn. The range of observed activity was 7.6 to 16 pCi/g (dry).
I The data from indicator locations are consistent with preoperational and control data.
1 The results of the analysis of sediment samples for gross beta activity are listed in Table 9. All 15 sediment samples had detectable activity with a mean of 16.7 pCi/g (dry). The mean for the 11 indicator stations is 25.6 pCi/g (dry) and the mean for the 4 control stations is 29.5 pCi/g (dry).
The range of the indicator stations is 15 to 39 pCi/g (dry) and the range of the control stations is 23 to 35 pCi/g (dry). The results from the indicator locations are consistent with the results from the control locations and with data reported in previous years. The gross beta results can be attributed to naturally occurring radium, thorium and potassium-40 contained in the sediment.
LIV-9
A number of naturally crcurring radioisotopes were detected in these samples. Potassium-40 was detected in all samples, ranging from 7.7 to 19 pCi/g (dry). Beryllium-7 was detected in 8 of 15 samples, ranging from 0.30 to 1.7 pCi/g (dry). Radium-226 was found to be present in 14 of 15 samples and Thorium-228 was found in all 15 samples.
The man-made isotope Cesium-137 was detected in 12 of 15 samples.
Cesium-137 was detected in 3 of 4 control samples and ranged from U.18 to 0.25 pCi/g (dry). Cesium-137 was also detected in 9 of 11 indicator loca-tions at concentrations ranging from 0.04 to 0.36 pCi/g (dry). Since the data from indicator locations are consistent with preoperational and control data and the presence of Cs-137 can be explained by previous atmospheric weapons testing, it is felt that the Cs-137 is not from the operation of SSES.
Detectable levels of Mn~54, C0-511 and Co-60 were observed in sediment from some indicator locations. The presence of these radioisotopes is consistent with the data reported from surface water and can be attributed to the operation of SSES. Manganese-54 was found in 3 of 11 indicator samples at concentrations ranging from 0.03 to U.73 pCi/g (dry). Cobalt-58 and cobalt-60 were each detected once at levels of 0.15 and 0.42 pCi/g (dry), respectively. The calculated dose to the maximally exposed individual from these gamma emitting radionuclides is presented below in sect ion IV-L.
IV-10
G. Ground (Well) Water A total of 102 ground (well) water samples were collected during this program period. These samples were analyzed for gross alpha and gross beta, l tritium and gamma emitting radionuclides. The results are presented in l
Table 10.
Of the 89 indicator ground water samples, 8 had detectable gross alpha activity, ranging from 0.69 to 5.0 pCi/ liter. No detectable alpha activity was seen in the control samples. These data are within the range of pre-operational data.
Gross beta activity was detected in 54 of the 89 indicator samples. The range of concentration was 0.86 to 5.7 pCi/ liter. Of the 13 control ground water samples analyzed,12 had detectable gross beta activity, ranging from 0.79 to 3.3 pCi/ liter. These values are within the ranges of preoperational data.
Tritium activity was found in 71 of 89 indicator well water samples.
The average concentration was 116 pCi/ liter and the range was 60 to 280 pCi/ liter. Of the 13 control well water samples analyzed,12 had tritium activity with a mean concentration of 109 pCi/ liter. The range was 78 to 230 pCi/ liter. All tritium levels are within the range noted in preopera-tional reports.
Gamma spectrometric analyses of the well water samples revealed the typical concentrations of naturally occurring radionuclides. Potassium-40 was detected in 13 of the indicator samples and 1 of the control samples.
Thorium-228 was detected in one indicator sample. The fallout radionuclide cesium-137 was detected twice with an average concentration of 4.3 pCi/ liter.
l Due to the above observations, it is concluded that operation of l Susquehanna SES has not resulted in a detectable increase of radioactivity i
in ground (well) water. IV-ll
1 H. Air Particulates/ Air Iodine-131/ Precipitation Air Particulate Air filters were collected weekly from 11 locations. Each weekly filter was analyzed for gross beta activity. Quarterly composites were analyzed for gamma emitting radionuclides and for gross alpha activity.
Results of gross beta analyses on air particulate filters are given in Table 11. The mean gross beta activity for all stations was 16.3
~
and the range of gross beta ctivity was 3.3 to 36.0 E-03 pCi/m 3 . Figure 4 illustrates the variation of beta activity in airborne particulates over the program year. Comparison of this data with that of previous years shows no-significant difference in activity. Figure 5 shows the data 'from the current reporting period in the context of reported measurements for the program over the period 1973 through 1985.
Results of gross alpha analyses on air particulate filters are given I .
in Table 12. The mean gross alpha activity for all stations was 3.9 E-03 pCi/m3 and the range of gross alpha activity was 0.9 to S.8 E-03 pCi/m3 .
The average activity in the sample from the indicator' locations was 4.0 E-03 pCi/m3 . The average activity in the sample froin the control locations 3
was 3.6 E-03 pCi/m . All gross alpha activity measured on air particulate-filters in this program year falls within the range of preoperational data.
IV-12
Air filters from each location were composited quarterly and analyzed by gamma spectrometry. A total of 44 composited samples were analyzed and the results are presented in Table 12. Several naturally occurring radio-nuclides were detected on these filters. Cosmogenic bery111um-7 was detected in all samples with a range of activity from 53 to 95 E-03 pCi/m3.
Potassium-40 was detected in 25 of 44 samples with a mean activity of 4.2 E-03 pCi/m3 The only man-made radionuclide detected was the fallout radionuclide cesium-137 which was detected on 2 of 12 control samples with a mean of 0.2 E-03 pC1/m3. Cesium-137 was measured on one of 32 indicator locations at a level of 0.3 E-03 pC1/m3.
Due to the above observations, it is concluded that operation of Susquehanna SES has not resulted in a detectable increase of particulate activity in the environment.
Air Iodine Results of airborne iodine-131 analyses on charcoal cartridges are presented in Table 11. Iodine-131 was not detected in any of the samples.
t Precipitation Precipitation was composited to quarterly samples from eight indicator and two control locations. Samples were analyzed for gross alpha, gross 4
beta, tritium and gamma activity.
The results of gross alpha and gross beta are shown in Table 13. Alpha was detected in one indicator sample at a level of 0.61 pCi/ liter.and in one control sample at a concentration of 0.93 pCi/ liter. Beta activity was observed in all samples. The average activity in .the samples from the indicator and control stations were 2.5 and 3.4 pCi/ liter, respectively.
IV-13 l

-vv -
1 The results of the gamma spectrometry analysis are shown in Table 13.
Cosmogenic beryllium-7 was detected in 19 of 44 samples. The range of beryllium -7 activity was 24 to 110 pCi/ liter. Potassium-40 was detected in 5 of 44 samples with a mean activity of 31 pCi/ liter. The naturally occurring radioisotope of thorium-228 was detected in 4 samples.' The range o' thorium-228 concentration was 8.9 to 29 pCi/ liter. The fallout radionuclide l cesium-137 was detected in one indicator sample at a concentration of 3.4 pCi/ liter.
Results of the analyses for tritium are contained in Table 13. ,
Tritium was detected in 6 of 9 analyses of samples from control locations and in 30 of 35 analyses of samples from the indicator locations. The inean concentration of tritium detected at the control locations was 114 pCi/ liter and at the indicator location the mean concentration was 116 pCi/ liter.
These results are typical for environmental samples and are within the ranges previously reported in Susquehanna SES annual reports.
Due to the above observations, it is concluded that operation of Susquehanna SES has not resulted in a detectable increase of radioactivity in precipitation in the environment.
'l
- 1. Milk / Pasture Grass Milk Monthly and semimonthly milk samples were analyzed for iodine-131 by radiochemical methods and for other gamma emitting radionuclides by gamma
{ spectrometry. All samples were also analyzed for beta activity after potassium had been chemically extracted. Some samples with high beta activity were analyzed for strontium 89 and 90 activity. The results of all i ~
analyses are shown in Table 14.
IV-14
No iodine-131 was detected in any milk samples.
Using gamma spectrometry, naturally occurring potassium-40 was detected in all samples. The man-made radionuclide cesium-137 was detected in 3 of 22 control samples and 2 of 122 indicator samples. The mean concentration of Cs-137 was 4.4 pCi/ liter for the control samples and 4.8 pCi/ liter for the indicator samples. The presence of Cs-137 in these samples is attributed to global fallout from previous atmospheric weapons testing.
The analysis of gross beta following chemical extraction of potassium is shown in Table 14. The control samples exhibited beta activity in all 22
{
samples. The mean activity was 9.1 pCi/ liter and the range was 5.3 to 16 pCi/ liter. For the indicator samples beta activity was detected in 110 of the 122 samples. The average concentration was 7.3 pCi/ liter with a range of 2.5 to 26 pCi/ liter. Of the 144 total samples, one control and seven indicator samples had beta activity higher than 14 pCi/ liter. Five of these eight samples were analyzed for Strontium-89 and Strontium-90 activity.
Strontium-89 was not detected in any sample. Strontium-90 was found ~in the control sample at a concentration of 6.9 pCi/ liter and in the four indicator samples analyzed at a mean concentration of 7 pCi/ liter. These values are within the ranges reported in preoperational data. The presence of Sr-90 in these samples is attributed to global fallout from previous atmospheric weapons testing. .
From the observations presented, there is no indication of the presence of any radionuclide in milk attributed to the operation of Susquehanna SES.

Pasture Grass A total of 14 pasture grass samples were collected for analysis during this program year. Samples were collected monthly except when the ground was covered by snow and ice. All samples were analyzed by gsmma spectrometry. Results of gamma spectrometric analyses of these samples are contained in Table 15.
Cosmogenic beryllium-7, which exists due to its deposition as stratospheric fallout, was found in all 14 samples. Potassium-40, a naturally occurring isotope, was also found in all the samples. Table 3 contains the summarized average, fraction of detectable, and range of radionuclide concentrations. The observed values for both beryllium-7 and potassium-40 were within the expected range of normal distribution.
There is no indication of the presence of any radionuclide in grass attributed to the operation of Susquehanna SES.
J. Vegetation, Top and Bottom Soil A total of 30 vegetation and soil samples were collected for analysis during this program year. These samples consisted of 10 vegetation,10 from the top two inches of soil and 10 from the bottom soil (2-6 inches deep).
The results of the gsama spectrometric analysis are presented in Table 16.
Cesium-137 was present in 20 of 20 soil samples and in none of the vegetation samples.
Radium-226 was found to be present in 16 of 20 of the soil samples and none of the vegetation camples. Radium-226 is a naturally. occurring isotope and was observed within the expected range of normal distribution.
IV-16
Thorium-228 was found to be present in all of the 20 soil samples and none of the vegetation samples. Thorium-228 is a naturally occurring isotope and was observed to be within the expected range of normal distribution.
Cosmogenic beryllium-7 was found in all ten of the vegetation samples but none of the soil samples. Potassium-40, as expected because it is a l
l naturally occurring isotope, was found to be present in all of the soil and vegetation samples. The observed values were within the expected range of normal distribution.
There is no indication of the presence of any radionuclide in these vegetation and soil samples attributed to the operation of Susquehanna SES.
K. Food Products A total of 50 fruit, vegetable and food product samples and 8 game, poultry and egg samples were collected for analysis during this program year. Samples were collected as available during the harvest season. All samples were analyzed by gamme spectrometry.
Fruits, Vegetables and Honey A total of 50 edible food samples were collected from various gardens over the period June through October. These samples consisted of cabbage, lettuce, swiss chard, beans, corn, potatoes, apples, spinach, tomatoes, strawberries and honey. Results of gamma spectrometric analyses of food samples are contained in Table 17.
IV-17
Cesium-137 was detected in 3 of 50 food samples at an average activity of 0.02 pCi/g (wet). The single sample of honey contained 0.03 pCi/g of Cs-137. This data is consistent with data obtained from prior years. Since i
it is present in global fallout, the occasional detection of Cs-137 in environmental media is not unusual. No other man-made nuclides were detected 1
in any of the 50 samples.
Cosmogenic bery111um-7, which exists due to its deposition as stratospheric fallout, was found in 19 of the 50 samples. Potassium-40, a naturally occurring isotope, was found in all the samples. Table 3 contains the summarized average, fraction of detectables and range of radionuclide concentrations.
There is no indication of the presence of any radionuclide in food products attributed to the operation of Susquehanna SES.
Game, Poultry and Eggs In addition to the samples discussed above, a total of 8 non-vegetable food product samples were collected for analysis during this program-year.
These included squirrel, deer, duck, poultry and eggs. All. samples were analyzed by gamma spectrometry. Results are contained in Table 18.
Potassium-40, a naturally occurring isotope, was found in all the
! samples at its expected ranges of activity. Table 3 contains the summarized average, fraction of detectables, and range of radionuclide concentrations.
IV-18
As expected, the sample of squirrel meat contained high levels of cesium-137 relative to all other types of food products sampled. These elevated activities have been reported previously in the annual reports on the Susquthanna SES REMP and in other sources. (19) Cesium-137 was detected in all squirrel meat samples at an average activity of 2.6 pCi/g (wet). This is consistent with previously reported values. Since it is present in global fallout, the occasional detection of cesium-137 in environmental media is not unusual. The comparatively high levels in squirrel meat apparently result from high concentration factors in the components of the squirrel's diet. Detectable levels of cesium-137 were found in the deer samples, at the mecn level of 0.23 pCi/g (wet). No other man-made nuclides were detected in any of the samples of food product analyzed.
There is no indication of the presence of any radionuclide in these food products attributed to the operation of Susquehanna SES.
L. CALCULATED DOSE TO THE MAXIMALLY EXPOSED INDIVIDUAL As shown from the discussion above the only radioactivity detected in the environment from the operation of Susquehanna SES was in the surface water pathway. Specifically, slight amounts of radioactivity were detected in the composite sampler on the station discharge line (6S7), in some algae samples collected from the Susquehanna river downstream of the discharge and in some sediment samples collected from the Susquehanna river downstream of the plant. To judge the impact of these observations the hypothetical dose to the maximally exposed individual is calculated from both surface water and sediment. Iy_19
Surface Water The dose contribution received by the hypothetical maximally exposed individual from the radioactivity found in the surface water samples was determined using the methodology in the Susquehanna SES Offsite Dose Calcu-lation Manual (ODCM). (25) To use the methodology expressed in the ODCM, the total activity released must be estimated. As all positively detected surface water radioactivity attributed to Susquehanna SES operation was found in the discharge line composite sampler (6S7), the total activity of H-3, Cr-51, Mn-54, Co-58, Co-60, and Zn-65 released was estimated by multiplying the mean detected concentrations by the total volume of water that passed through the discharge line during the one year reporting period.
The total amount of water was estimated by assuming a discharge rate of 10,000 gallons per minute for the entire year. The mean or average concentrations of Cr-51, Mn-54, Co-60 and Zn-65 are found in Table 3.
The net mean activity of H-3 was determined by subtracting the average surface water control value (113 pCi/ liter) from the average value of the discharge line (595 pCi/ liter). The mean activity of Co-58 released was estimated by multiplying the Co-60 activity by the Co-58/Co-60 ratio found in the indicator algae samples. The hypothetical maximally exposed individual is a child. The whole body was the organ that had the highest percent of the applicable limit. The total whole body dose is conservatively calculated to be 0.00534 mrem or 0.089% of the 6 mrem limit (as expressed in 10CFR 50 Appendix 1) and an even smaller percentage of the normally occurring ingestion dose from background radioactivity.
1 i
IV-20
Shoreline Sediment A hypothetical dose to a person from the radioactivity found in the shoreline sediment was calculated usino the methodology found in Regulatory Guide 1.109. The assumption was made that the individual was exposed to 1
shoreline sediment containing Mn-54, Co-58 and Co-60 at the mean detected concentrations as listed in Table 3 for 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> per year. A shore-width factor of 0.2 was used to describe the geometry of the exposure. The whole body was the organ that had the highest percent of the applicable limit.
The hypothetical total whole body dose is conservatively calculated to be 0.00526 mrem or 0.088% of the 6 mrem limit (as expressed in 10CFR 50 Appendix I). The hypothetical skin dose was 0.00636 mrem. These values are well below the expected dose from exposure to naturally occurring radioactive materials.
IV- 21
l V. DEVIATIONS FROM THE PROGRAM
DEVIATIONS FROM THE PROGRAM 1985 The required analysis sensitivities were met throughout the year. The program sampling schedule was adhered to, except as discussed below.
TLDs at locations 7F1 and 14S6 were vandalized during the year. The poles and TLDs were destroyed at locations 1A1, 6A3 and 8D2. These devia-tions are noted in Table 5. See PROGRAM CHANGES for new locations for 6A3 and BD2. The entire residence was razed at location 1A1. It was decided that the TLD located nearby at 16A2 was adequate for monitoring in this community.
The time proportional surface water automatic composite samplers at locations 6S6, 6S7 and 12H2 RAW malfunctioned infrequently during the year.
These deviations are noted in Table 6. Corrective actions were completed prior to the end of the next sampling period. These samplers are not flow proportional.
The pump for ground (well) water location AS2 was temporarily out of service in November. Location 3SS is closed down seasonally from November through April. These deviations are noted in Table 10.
Various air samplers malfunctioned infrequently during the year.
These deviations are noted in Table 11. Corrective actions were completed prior to the end of the next sampling period.

I VI. PROGRAM CHANGES 4
-- m -. -.. -
j PROGRAM CHANGES - 1985 Changes to the REMP were made in 1985 to provide more uniformity in the analysis performed. These changes are noted.
- 1. Surface Water - Iodine-131 analysis at locations 6S6 and 657 was changed from weekly to monthly.
- 2. Drinking Water - Iodine-131 analysis at locations 12H2 Raw and 12H2 Trented was changed from weekly to monthly.
! Various sampling locations were added, deleted, moved or given a new l code as noted below.
- 1. Surface Water - Locations 105 and 13E1 were discontinued from the sampling program. Location 1DS was a redundant up-river location which is sufficiently monitored by locations 1D3, SS8 and 6S6.
Location 13E1 is not a good indicator location as it is beyond the influence of any aquatic discharge from the plant.
- 2. Drinking Water - L( ,:ation 12F3 treated was deleted. The ground (well) water location 12F3 was retained to monitor 8erwick water.
- 3. Milk - The goat mili< location 8D1 was discontinued after the goat milking operation was discontinued in May.
- 4. Pasture Grass - Location 8D1 was discontinued after the goat milking operation was discontinued in May.
- 5. TLDs - Location 1 A1, 8D2 and 6A3 were destroyed during the second, second and fourth quarters, respectively. New nearby locations were begun the fourth quarter for 8D2 at 8D3 and for 6A3 at 6A4.
- After a careful review of aerial photos and site survey maps, it was discovered that three TLDs were actually located in adjoining sectors. Location 7S1 became 658, location 753 became 659 and location 15S3 became 16S2 beginning the third quarter.
- Location 7S1/658 is a 12KV pole no. 44316/N34036, not a 230KV Tower.
- Two new locations were added at the third quarter due to the above code changes. They are locations 7S6 and 15S5.
- Six new locations were added during the third and fourth quarters to better characterize the radiation environment.
These locations are 10S2, 13S4, 1355 (third quarter) and 1456, 7A2, 8A2 (fourth quarter).
L
- Location 12G4 became the Naus residence in August.

f VII. LAND USE CENSUS i
r VII. LAND USE CENSUS The USNRC Branch Technical Position on "An Acceptable Radiological Environmental Monitoring Program" (November 1979, Revision 1), states that "a census shall be conducted annually during the growing season to determine the location of the nearest milk animal and nearest garden greater than 50 square meters (500 sq. ft.) producing broad leaf vegetation in each of the 16 meteorological sectors within a distance of 8 km (5 miles)." To comply with this requirement, a land-use survey was conducted for the Susquehanna SES during the period June 26, 1985 through August 8, 1985. The closest garden (greater than 50 square meters, producing broad leaf vegetation) and l
residence in each radial sector was determined and all dairy animals within five (5) miles were identified.
Table 4 lists the nearest dairy animals, the nearest garden and residence in each sector identified during the survey. These land-use parameters are used in the assessment of potential radiological doses to individuals and populations of the stated regions.

'l3 VIII. CONCLUSIONS Results of the 1985 Radiological Environmental Monitoring Program for ' .
the Susquehanna SES Nuclear Station have been presented. Generally, the results were as expected for normal environmental samples. Naturally cccurring activity was observed in the usual sample media at the expected t '
magnitude. .
t A few man-made isotopes, in particular cesium-137, were also observed in a variety of sample types. These were also generally present at the ,
anticipated concentrations and are attributable to long-term fallout from 1
atmospheric nuclear weapons tests. A recurring detection of low levels of /
! I-131 in surface water samples was noted. The absence of.recent atmospheric j
testing rules out fallout as a source because of the short half-life of this
/
isotope. However, the pattern of detection is such that plant operations are not implicated. ,
j The program detected plant related radioactivity at very low levels
- in the composite sampler on the station discharge line, in some downstream J
algae samples and in some downstream sediment samples. These results support the results reported in the Semiannual Effluent and Waste Disposal reports for Susquehanna SES for 1985. (23 and 24)

APPENDIX A US EPA INTERCOMPARISON PROGRAM RESULTS h-
APPENDIX A US EPA INTERCOMPARIS0N PROGRAM RESULTS
- 1. Introduction The quality assurance program of the Radiological Laboratory of Teledyne Isotopes (TI) is briefly describ2d in this appendix.
Information on each incoming sample is entered in a permanent log book. A sample number is assigned to each sample at the time of receipt. --
This sample number uniquely identifies each sample.
Laboratory counting instruments are calibrated, using radionuclide standards obtained from the National Bureau of Standards, the EPA, and reliable commercial suppliers, such as Amersham-Searle. Calibration of counting instruments is maintained by regular counting of radioactive reference sources. Background counting rates are measured regularly on all counting instruments. Additional performance checks for the ganna-ray scintillation spectrometer include regular checks and adjustment, when necessary, of energy calibration.
Blank, spiked (known quantities of radioactivity added), and replicate samples are processed periodically to determine analytical precision and l accuracy.
- 2. Laboratory Analyses for Quality Assurance Teledyne Isotopes participates in the U.S. Environmental Protection Agency Radioactivity Intercomparison Studies (Cross-check) Program. The TI results of analyses performed on samples and the known values are listed in Table A-1.

(d) The results from.the EPA were received on August 09, 1985 for the analysis completed in April. The EPA had difficulty determining the correct results for this sample. It was difficult to scavenge and the -
results were reported as a courtesy although they were considered suspect because of the difficulty of analyzing a synthetic food sample.

SUMMARY
OF ANALYTICAL METHODS The following section contains a description of the analytical laboratory procedures along with an explanation of the analytical calculation methods used by Teledyne Isotopes for sample analysis. These are considered proprietary and are published for informational purposes only.
A further discussion on data reporting conventions can be found in Appendix C.

TLD MEASUREMENTS During the four quarters of 1985, a PP&L dosimetry system was used which consists of a Panasonic UD-710 reader and UD-801 badges. The UD-801 badges have two elements of lithium borate (Cu) and two elements of calcium sulfate (Tm). Only the calcium sulfate (Tm) elemento are used for environ-mental measurements. This phosphor was chosen for its characteristic high light output, minimal thermally induced signal loss (fading) and negligible self-dosing.
In handling, the badges are kept clean, and the element phosphors are not touched. The badges are stored and transported in plastic bags or other containers.
Before going to the field, the dosimeters are read twice (separated by one hour) in which the second reading is used as an inherent (background) reading for each element. After the inherent read, the badges are placed in sealed plastic bags (to aid in preventing moisture contacting the TLDs)'
labeled with the sampling location and taken immediately out to the field.
Upon removal from the field, the TLDs are inspected for any damage and readout immediately. In-transit TLDs are not used because of the short time period between the inherent reading and field placement.
l An element correction factor has been calculated for each element, and the reader is calibrated using a cesium-137 source.

DETERMINATION OF GROSS ALPHA AND/0R GROSS BETA ACTIVITY IN WATER SAMPLES, AIR PARTICULATE FILTERS, COMPOSITED AIR.
PARTICULATE FILTERS OR SEDIMENTS TELEDYNE IS0 TOPES This describes the process used to measure the overall alpha and/or beta radioactivity of water sanples, air particulate filters, composited air particulate filters or sediments without identifying the radioactive species present. No chenical separation techniques are involved. One liter of the water sample is evaporated on a hot plate. The evaporated 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. Residue mass is determined by weighing the planchet before and after mounting the sample. In the case of an air particulate sample, the filter is mounted directly on a 2-inch stainless steel planchet. Composited air filter sample' a leached with nitric acid to bring the deposit into solution. The so' . ion is filtered and a aliquot is evaporated and then mounted on a 2-inch stainless steel planchet. Sediment samples are dried and a 1 gram aliquot is mounted directly on a 2-inch stainless steel planchet, i
The planchets are then counted for alpha and/or beta activity in a low-background gas flow proportional counter. Calculation of activity includes an empirical self-absorption correction curve hich allow for the change in-effective counting efficiency caused by the residue mass. Self absorption is not considered in the case of air particulate filters because of the impracticality of accurately weighing the deposit and because the penetration depth of the deposit into the filter is unknown.

DETERMINATION OF I-131 IN MILK AND WATER SAMPLES BY RADI0 CHEMISTRY AND LIQUID PHASE BY ANALYSIS TELEDYNE ISOTOPES This describes the radiochemical methods for determining I-131 activity in milk and water samples by coincidence counting in the liquid phase.
Four liters of sample are first equilibrated with stable iodide carrier. A batch treatment with anion exchange resin is used to remove iodide from the sample. The iodine is then stripped fran the resin with sodium hypochlorite 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. I The iodide sample solution is oxidized to the free state using nan 02 reagent and is extracted several times into a total of 15 ml of toluene. A 200 p1 aliquot is taken for' determining chemical yield by spectrophotometer. A decolorizing agent (2-methyl-2-butene) is added to the toluene-iodine solution to form an inert molecule and to minimize liquid scintillation quenching. A toluene-based liquid scintillation counting solution is added to the sample, which is then analyzed by a beta-gated gamma-coincidence counting system.

Consequently, the branching intensity (abundance) of the I-131 gamma does not appear in the above equation.
Calculation of the MDL If the net activity (previously defined) is equal to or is less than a specified multiple of the background counting error, the activity on the collection date is below the limits of detection and is called "less than" (L.T.) or " minimum detectable level" (MDL).
The L.T. value can be specified by stating only the counting error at a predetermined multiple (rm) of the one sigma sta-tistics. A sigma multiple (am) of 4.65 is used for calculation of the L.T. values unless another multiple such as 2.83 is specified.

DETERMINATION OF GAMMA EMITTING RADI0IS0 TOPES TELEDYNE ISOTOPES Gamma emitting radioisotopes are determined with the use of a lithium-drifted germaniun (Ge(Li)) and high purity germanium detectors with high resolution spectrometry in specific media, for example, air particulate filters, charcoal filters, milk, water, vegetation, soil / sediments, biological medi a, etc. Each sample to be assayed is prepared and counted in standard geometries such as one liter wrap-around Marinelli containers, 300 mt or 150 mt bottles, or two-inch filter paper source geometries.
1 Samples are counted on large (>55 cc volume) Ge(Li) detectors connected to Nuclear Data 6620 data acquisition and computation systems. All resultant spectra are stored on magnetic tape.
The analysis of each sample consists of calculating the specific activities of all detected radionuclides or the detection limits from a standard list of nuclides. The Ge(Li) systems are calibrated for each standard geometry using certified radionuclide standards traceable to the National Bureau of Standards.

where: N = area, in counts, of a spectral region containing a gamma emission of the nuclide of interest Note: if the detector exhibits a peak in this region when counting a blank (ie. from natural background) then (BB)(At) is subtracted from N before using the above equation. BB is the count rate of the blank, cpm, in the background peak.
B = background counts in the region of interest, calculated by fitting a straight line across the region connecting the two adjacent regions.

The width of the spectral band around the emission energy is calculated differently from the case of an identified peak, so that the value of N used in the two equations may differ.
A detection limit (MDL) or "less than" (LT) value is reported if no activity is found. If no spectral lines are identified at the energies appropriate to a nuclide, the LT value is calculated by the above equation.
If spectral lines are identified but the 2 sigma error in the first equation is greater than 60% of the net activity, then a LT value is also assigned by the second equation.
The analyst's judgement is excercised in the decision to report an activity or an MDL. The agreement between various spectral lines of the same nuclide, and possible interference from other nuclides, are considered in this decision.

APPENDIX C DATA REPORTING CONVENTIONS
APPENDIX C DATA REPORTING CONVENTIONS The results from Teledyne Isotopes analyses are reported to two significant figures. Errors are reported to the same decimal place as the result. If the error has no digit before the third figure in the result, the error.is rounded up to the second significant figure, if the error is less than 10% of the result, an error of 10% of the result is reported. Detection limits are rounded to one significant figure.
In the tables presenting analytical measurements, the caiculated value is reported with the counting error of 2 standard deviations (2s) derived from a statistical analysis of both the sample and background count rates.
The precision of the results is influenced by the size of the sample, the background count rate, and the method used to round off the value obtained to reflect its degree of significance. For the results of gamma spectrometric analysis, the precision is also influenced by the composition and concentra--
tions of the radionuclides in the sample, the size of the sample, and the assumptions used in selecting the radionuclides to be quantitatively deter-I mined. The 2s error for the net counting rate is-- ')

Results. reported as less than (LT) are below the lower limit of detec-tion (LLD). The LLD is defined as the smallest concentration of radioactive material in a sample that will yield a net count (above system background) with a 95 percent probability of detection and with only a 5 percent prob-ability of f alsely concluding that a blank observation represents a "real" sign al .

The folowing are d:finitions of statistical terms used in analyses and reporting of environmental-monitoring results:
- 1. Mean(or average or arithmetic mean) A measure of the central value of a set; the sum of all values in a set divided by the number of values in that set. The mean is expressed as follows: I X = (X1+X2 + ...Xn)/n = Xi /n i=1
- 2. Precision The reproducibility of measurements within a set; the scatter or dispersion of a set about its central value.
- 3. Measures of precision with a set
- a. Standard deviation The precision with which the values of a set are measured; the square root of the value yielded by division i of the sum of squares of deviations of individual values from the mean by one less than the number of values in the set. The standt.rd deviation, s, is expressed as follows:
n s= E (Xj - X)2 /(n-1) i=i The standard deviation has the same units as the result. It becomes a more reliable expression of precision as n becomes larger. When the measurements are independent and normally distributed, the most useful statistics are the mean for the central value and the standard deviation for the dispersion,
- b. Relative standard deviation The standard deviation expressed as a fraction of the mean, x/Y. It is sometimes multiplied by 100 and expressed as a precentage,
- c. RE.3e, The difference in magnitude between the highest and the lowest values in a set. Instead of a single value, the actual limits (i.e., minimum value/ maximum value) are sometimes expressed.
