- 1. INTRODUCTION This report contains a complete tabulation of data collected during
~ the period January through December 1987, for the operational Radiological Environmental Monitoring Progra performed for the Cooper Nuclear Station (CNS) of the Nebraska Public Power District (NPPD) by Teledyne Isotopes. Cooper Nuclear St ation is located in Nemaha County in the southeast corner of Nebraska on the Missouri River. A portion of the site extends into Missouri. The reactor is a 778 megawatt boiling water reactor. Initial criticality was attained on February 21, 1974 The reactor reached 50% power on June 25, 1974 and 100% power on November 20, 1974. Radiological environmental monitoring began in 1971 before the plant became operational and has continued to the present. The program m6nitors radiation levels in air, terrestrial and aquatic environments. ftst samples are collected by NPPD personnel. All are shipped for analysis to a con-tractor's l aboratory where there exists special f acilities required for measurements of extremely low levels of radioactivity. From 1971 through 1976 the contractor was Teledyne Isotopes, Westwood, New Jersey. ' NAt;CO Environmental Sciences ~ assuned responsibility for the analyses effective . January 1, 1977. . - On November 1,1978 Hazelton Environmental Sciences Corporation (HESC) - assurped responsibility for the program. Prior to November 1,1978 Hazelton Environmental Sciences operated as NALCO Environmental Sciences. Teledyne Isotopes again assumed responsibility for the analyses effective January 1, 1979 through December 31, 1987. e 1

SUMMARY
Presented in this report are summaries and discussions of the data generated for the Radiological Environmental Monitoring Program (REMP) - for the Cooper Nuclear Station (CNS) of the Nebraska Public Power District (NPPD) for 1987. Part V, Table 3 preser.ts the yearly sunmary of the program with the total number of samples of each type analyzed, the yearly average for all samples, the number of detections per total number of samples, the station with the highest average, the average of the control station, and the in-clusive dates of the analyses. Part VI is a discussion of each type of sample analyzed and its impact, i f any, on the environment. Included also is a graph of the isotopes of interest since 1977 and the statistical results for each quarter of the year. This is followed by a complete tabulation of the data by sample type and station number. The 1987 radiological environmental measurements for CNS indicates that there has been no residual f allout resulting from the explosion and fire at the Chernobyl Reactor in the Soviet Union which occurred on April 26, 1986. ~ It may be concluded from all measurements taken that the operations of CNS had no detectable impact on the environment in the vicinity of CNS. . e 4 s O e 2
TM ' ISOTOPES III. SAMPLING AND ANALYSES PROGRAM, STATIONS AND MAPS The 1987 sampling and analysis program is described in Table 1. Teledyne Isotopes has a comprehensive quality assurance / quality control progran designed to assure the reliability of data obtained. The results for 1987 of the Intercomparison Program conducted by the EPA Environmental Monitoring Systems Laboratory in las Vegas, Nevada, are contained in Ap-pendix B. Sampling locations are sunmarized in Table 2. The type or status of each location and its distance and direction from the reactor elevated release point are specified. A map of locations follows (Figure 1). Complete descriptions of current and earlier sampling locations are given in Appendix I. The annual land use census for 1987 is described in Appendix A. There were no milk animals found within three miles of CNS. The nearest gardens were 2.7 miles fran CNS in Sector F and 2.2 miles froe. CNS in Sector L.

1PTE. EDGE ISOTOPES IV. DISCUSSION A. Procram Objectives and Data Interpretation
- The objective of the monitoring program is to detect and assess the impact of possible releases to the environs of radionuclides from the oper- '
ations of the Cooper Nt: lear Station. This objective requires measurements of low levels of radioacMvity equal to or lower than pre-determined limits of detection. In addition the source of the environmental radiation must be established. Sources of environmental radiation include: (1) Natural background radiation from cosmic rays (Be-7). (2) Terrestrial, primordial radionuclides from the environment (K-40, Ra-226, Th-228). (3) Fallout from atmospheric nuclear tests such as the September 1977 detonation by the Peoples' Republic of China and the atmo-spheric weapons test of October 16, 1980. (fission products and fusion products). (4) Releases free nuclear power plants such as CNS (fission products and neutron activation products). (5) Fallout from tne. Chernobyl Nuclear Reactor Accident. , A number of technicues are used to distinguish power plant effects from other sources. Radiation levels measured in the vicinity of an oper- - ating power station are compared with preoperational measurements at the saae loc tions. Measurements at indigator locations (nearby, downwind, or down- - stream) are compared with measurements made at. distant points such as - stations of the nationwide Environmental Radiation Ambient Monitoring System (ERAMS) operated by the U.S. Environmental Protection Agency (EPA) or - stations operated worldwide by the Environmental Measurements Laboratory (EML) (formerly called the Health and Safety Laboratory or HASL) of the U.S. Department of Energy. Also, results cf the monitoring progran are related to events known to cause elevated levels of radiation in the environment, e.g., atmospheric nuclear detonations or abnormal plant releases. B. Atmospheric Nuclear Tests Three atmospheric nuclear detonations in the People's Republic of China influenced program results significantly in late 1976 and in 1977. Two of these detonations occurred in late 1976 (September 26 and November 17) and one in late 1977 (September 17). As a consequence of these tests elevated activities of gross beta in air particulate filters and I-131 in milk were observed throughout most of the United States. No atmospheric nuclear tests were conducted during 1979 thus no short-lived fission products were detected in air particulate samples. Also no I-131 was detected from radiogases from any sources.
- On April 26, 1986 the fire and explosion of Chernobyl Reactor No. 4 .
in the Soviet Union resulted in the release of fission products to the atmosphere and worldwide fallout. Following the explosion, elevated levels of gross beta activities in air particulates and I-131 in charcoal filttrs - and milk samples were measured. Addi'tionally, in 1986, Cs-137 and the 10
. l WTE. EDGE 8CMCPES short-lived isotopes I-131, Ru-106, and Cs-134 were detected in broadleaf vegetation. Similar results occurred in other areas of the United States and the entire Northern Hemisphere.

WTELEDGE ISOTOPES V. RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM TABLES Presented in Table 3 are the radiological environmental monitoring program summaries (REMPS) generated from the reports of analyses performed during 1987 for the NPPD sampling and analyses program. The REMPS tables - conform to the requirements of Tabic 1 in Regulatory Guide 4.8 (Reference 6). The average activity level for all samples collected for the year for each sample type are summt-hed in this table. The mean, range and fraction of detections to total sam; .:s assayed are presented. The station location and station number with the nighest annual mean is also tabulated. If a control station is specified the comparable results of the control are listed. From the REMPS table it is possible to determine the total number of each type of sample analyzed and the average activity of all samples from all stations of each nuclide. If there were no positive, detections the maximum of the lowest levels of detection is listed. The station havino the highest level of activity is specified. From this data it is possible to determine any high levels of activity and the source. The dose impact on the popula-tion can thus be evaluated. . 9 4 0 6 e b e 12

WM 80 TOPES l l A and B. AIR PARTICULATE SAMPLES - GROSS BETA AND GROSS ALPHA (See Tables A A-4, 8 B-4)
- STATIONS 01 to 10 Air particulates were collected on membrane filters at ten locations (01-10). The filters were changed weekly and analyzed for gross beta and gross alpha activities. Quarterly composites are analyzed for gama emit-ting isotopes.
The average gross beta activity of all stations for each quarter of 1986 and 1987 is summarized below: , , 1986 First Quarter 0.025 pC1/Cu. M. Second Quarter 0.079 pCi/Cu. M. Third. Quarter 0.022 pCi/Cu. M. Fourth Quarter 0.031 pCi/Cu. M. - Average 1986 0.039 pCi/Cu. M. . 1987 First Quarter 0.023 pCi/Cu. M. - Second Quarter 0.021 pCi/Cu M. . Third Quarter 0.023 pCi/Cu. M. - Fourth Quarter 0.026 pCi/Cu. M. - Average 1987 0.023 pCi/Cu. M. The level of beta activity was at normal environmental levels in 1987 - showing the natural seasonal variations. There was a slight increase in the level of gross beta activity during the fourth quarter as shown in Table A-4. This increase in activity often occurs and is attributed to natural phenomena. The gross alpha activity continued low and close to the limits of detection. Gross alpha activity is probably due to the alpha emitters found in soil and particulates drawn into the filters. No effect attributable to the Cooper Nuclear Station was observed in the results of monitoring air particulates. The air particulate filters listed below were not radioassayed for the reasons shown in the table. COLLECTION > STATION FILTER PERIOD REASON NOT ASSAYED . 01 AP 05/26-06/01 Lost to environment 04 AP 06/01-06/10 Not collected (a) . (a) Sample not collected -- power failure. 28
i 0 SP N N L A and B. AIR PARTICULATE SAMPLES - GROSS BETA AND GROSS ALPHA (See Tables A A-4, B B-4) STATIONS 01 to 10 , Figure A1, B1 shows the gross beta, gross alpha and Ce-144 activity in the environs of CNS. The results for 1986 and 1987 are on the second page of Figure A-1, 8-1. The gross beta activity in 1987 was similar to previous years in which there were no nuclear atmospheric weapons tests or nuclear accidents. The gross alpha activity remained low and near the normal detection level. Cesium-144 was below the level of detection. Figure A-2. shows the gross beta activity in air smples through March 1987 at Jefferson City Missouri as reported by the Environmental Radiation Monitoring System (ERAMS) of the US Environmental Protection Agency. No more recent data was available. This data was taken from Reports 46-49 Environ-mental Radiation Data dis'tributed by the Eastern Environment al Radiation Facility, Montgomery, Alabma. The measurements by ERAMS were made after a waiting period which may explain the somewhat lower results because of decay of the isotopes having a shorter half-life. Measurements of Ce-144 were no lonaer reported because the activity has approached the limit of detection by the analytical techniques now used. e 9 29 1

- STATIONS 01 to 10 .
Charcoal filters used in series with air particulate filters were col-lected weekly during 1987 at stations 01 through 10 and monitored for radio-iodine. Tables C-1 through C-4 show the average monthly and quarterly results for each station and the average of all 10 stations. Airborne I-131 levels were below the limits of detection for all of 1987. Figure C-1 plots the results of I-131 as monitored in charcoal filters and sisnmarized monthly in 1987 compared with previous years. Results for 1987 were below the norml limits of detection indicating no atmospheric effect from the operations of CNS. e 0 e 9 A 9 l 42

, D. COMPOSITES OF AIR PARTICULATE FILTERS - GAMMA (See Tables 0-1 and 0-2)
STATIONS 01 to 10 Air Particulate Filters, which were collected weekly, were composited for each station for a cuarterly gamma spectral analysis during the four quarters of 1987. Beryllium-7, a naturalli occurring cosmogenic nuclide, was detected in 40 of 40 samples at a level of 0.1268 pC.i per cubic meter which is similar to the levels of past years. Potassium-40, also.a naturally occurring - nuclide, was detected in one of 40 samples at a level near the normal level of detection. Figure 0-1 graphs the gross beta, gross alpha and Ce-144 activity as measured on air particulate filters collected weekly at CNS. ( Th i s .i s the same as Figure A-1, 8-1). The plot- illustrates that there were no detections of Ce-144 above the normal level of detection as measured by the quarterly gamma scan of samples from CNS.
~
Figure 0-2 shows that measurements of Ce-144 are no longer reported by the Environment &l Measurements Laboratory of the U S Department of Energy - because the artificial nuclides such as Ce-144, have reached the limits of detection by the analytical techniques now used. l e l l 9 l 49 1

SPTELEDYNE ISOTOPES E. FISH (See Tables E-1, E-2) STATIONS 28, 35 ' Fish samples were collected during the summer and fall at the above stations and analyzed for gross beta, Sr-89, Sr-90 and gamma emitting isotopes. The gross beta and Sr-90 activities were similar to the levels of previous years. Strontium-90 was detected in six of eight samples at a level of 0.010 pCi/ gram, wet, which is below the normal level of detection. There were no detections of Sr-89. Naturally occurring K-40 was detected in eight of eight samples at an average level of 2.70 pCi/gm, wet. There was one detection of Cs-137 at a level of.0.024 pCi per gram wet, at Station 35, 2.0 miles, 350 degrees. This is below the normal detection level. There was no indication of an effect on fish samples from the operations of CNS. , Plotted in Figure E-1 are the radionuclides gross beta, K-40, Sr-90 and Cs-137 monitored in fish samples which show no appreciable. change from 1977 . through 1987. The plot of the nuclides shows that most of the gross beta , activity is due to the terrestr,ial nuclide K-40. -

TW6 ISvitats F. MILK (See Tables F-1, F-2) STATION 61 (NEAREST PRODUCER) Milk samples from the nearest producer Station 61, 3.5 miles, 326 degrees from the elevated release pcint of CNS were collected once every 15 days in peak pasture season and once every 31 days the rest of the year. The monthly samples collected January through May and October through December were analyzed for I-131 by chemical separation, for elemental calcium and strontium 89 and 90. In addition they were analyzed for gamma emitting isotopes on a high resolution gama spectrometer. The samples collected every 15 days during peak pasture season were analyzed upon receipt for I-131 and gama emitting isotopes. A monthly composite was prepared and analyzed as described above. There were no detections of I-131 in. the twenty-one samples analyzed by chemical separation. There were no detections of Sr-89 in the samples analyzed. Strontium-90 was detected at an average level of 2.1 pCi/ liter, which is a normal envir6nmental level. Elemental calcium was found at ..an average level of 2.0 mg/ liter. Potassium-40, a naturally occurring isotope,
- was detected at an average level of 1208 pCi/ liter.
There was one detection of the fission product Cs-137 in the first
- quarter. Cesium-137 was not detected throughout the remainder.of the year.
There was no indication of an effect on the miik of the producer nearest the plant from the operations of CNS. Shown in Figure F-1 and F-2 are the plots of radionuclides monitored from 1977 through 1987 in milk samples from producers nearest the reactor. The levels of K-40, elemental calcium and Sr-90 remained stable. There were no detections of I-131, Sr-89 or Cs-137. This indicates no effect on milk samples from the operations of CNS. e l . 61

G. MILK (See Tables G-1, G-2) . ; STATIONS 42, 95 (OTHER PRODUCERS) Milk samples were collected cuarterly from other producers within a ten mile radius of the plant. The samples were analyzed for 1-131 by chemical separation, for elemental calcium, for Sr-89 and 90 and for gamma emitting isotopes. Therte were no detections of I-131 in the eight samples monitored. There were no detections of Sr-89. Strontium-90 was found at an average level of 1.8 pCi/ liter. There were 2.0 mg of calciun per liter of milk. Potassium-40 was detected at an average sevel of 1289. pCi/ liter. Th e strontiun. 90, X-40 and elemental calcium were at normal environmental levels and were similar to the results obtained from analyses of milk from the nearest producer. There were no detections of Cs-137 in the samples col-lected. It can be concluded that the operations of CNS had no effect on milk , samples and thus no dose impact on the population. The levels of radioactivities of the nuclides K-40, I-131 and Cs-137 are plotted on Figure G-1. Potassium-40 was at normal environmental levels as , in previous. years. ' There were no detections of I-131 or Cs-137. Figure , G-2 shows that Sr-90 and elemental calcium are at a level comparable to previous years and there were no detections of Sr-89. These graphs indicate . that there was no appreciable difference between the levels of activity of - the nearest producer and the commercial producers. This indicated no effect on milk samples from the operations of CNS. 68

WTE.EPOE ISOTOPES H. GROUN0 WATER (See Tables H-1 and H-2) STATIONS 11, 47
. Groundwater was collected from two stations quarterly and analyzed for gross beta and gross alpha activity, for tritium and for gamma emitting radionuclides. Station 11 is 0.15 miles from the plant and station 47.is 25.75 miles from the plant.
The gross beta activity averaged 9.7 pCi/ liter which is statistically similar to past years. There were two detections of alpha activity at a level of 5.5 pCi/l often attributable to leaching processes of natural ground sources. There were no detections of gamma emitters above the normal level-of detection. The tritium, level averaged 150 pCi/ liter for the year which is the normal environmental level. ' There was no difference in levels of beta activity or tritium for the station close to the plant as compared with the more distant stati6n. It may be concluded that there was no impact from the operations of CNS on the
. environment as shown by measurements of radionuclides in groundwater. . Shown in Figure I-1 are the pross alpha, gross beta and tritium levels . in groundwater. The levels of these activities .have remained. essential.ly_. .

TTE. EDGE ISOTOPES I. RIVER WATER (See Table I-1 and I-2) STATIONS 12,28 , River water was collected monthly and monitored for gross beta and gross alpha, suspended and dissolved, Sr-89 and Sr-90 plus gamma emitting isotopes. A quarterly composite was measured for tritium. There were no detections of gama emitters above the normal level of detection. There were no detections of Sr-89 or Sr-90. The average gross alpha and gross beta readings were similar to previous years as indicated in the summary of 1986 and 1987 averages below: 1986 1987 Average pCi/ liter Average per/ liter Gross Alpha 4.7 5.3 (dissolved) . Gross Alpha 7.5 5.1 (suspended) - Gross Beta 9.4 11.4 (dissolved) Gross Beta 11.8 10.0 (suspended) Seasonal variations are reflected in the gross alpha and beta results. Changing weather conditions and flooding activity is responsible for the rise in suspended particles in the second quarter. Figure I-1, which follows, is a plot of the gross alpha and gross beta of suspended and dissolved particles. The results for 1987 are on the second page. The levels of activity continued to rise and fall within statistical limits depending on water levels and turbulence and were probably due to naturally occurring isotopes. No fission or reactor activation products were detected. Figure I-2 illustrates the level of activity for tritium, Sr-89 and Sr-90. 80

STATIONS 01-10,20,44,56,58,59,66,67,71,79-91,94 Ambient radiation was monitored at 32 locations within a 10 mile radius of CNS and collected quarterly. The quarterly averages for all stations of ambient net gamma radiation ranged from 15.7 milliroentgen / quarter to 29.4 milliroentgen / ouarter. The highest exposure during each of the four cuarters was at Station 01 (0.1 mile, 225 degrees) and averaged 29.4 mR/ ouarter. The lowest exposure was at Station 04 (3.0 miles, 43 degrees) averacing 15.7 milliRoenteen/cuarter.
> The radiation at station 44, (10.5 miles, 270 degrees) which is the control st ation, was an average of 19.0 mR/ quarter. This was similar to other stations and to the average of all stations which was 17.8 mR/ quarter.
The averace total exposure for the year was 70.9 mR which is consider-ably below the 125 millirems per quarter specified in 10 CFR 20.105 for an
- unrestricted area. The relationship between mil 11 Roentgen (mR) and millirems (mr) is approximately one for the exposure conditions encountered. No pl ant effect from CNS was indicated.
The ganma' exposures monitored by thermoluminescent dosimeters from 1977 through 1987 are plotted on Figure J-1. The data from year to year is in good agreement and indicates no adverse changes in radiation exposure to the population near CNS. i 1 e 87

WTELEDGE ' 80 TOPES K. VEGETATION, SROAOLEAF (SEE TABLES K-1 and K-2) STATICNS 35, 96, 97 , Broadleaf vegetation was collected each month during the growing season, May through October. Three suples were collected each month from each station plus a cuality control suple. The smples were tested for I-131 by chemical separation and for gamma emitting isotopes by high resolution spectrometry. The naturally occurring isotopes Be-7 and K-40 were detected in all of the smples at normal environmental levels. No I-131 was detected in any of the 59 smples. Cesium-137 was detected in one saple from Station 35, 2.0 miles, 350 degrees at 0.013 pCi/gm, wet. Cesitn-137 is detected in other areas of the United States and is attributed to fallout from previous atomic weapons testing. The mount detected from Station 35 is not con-sidered to be significant, , See Figure H-1 for the levels of activities in food suples as rep-resented in broadleaf vegetation in 1987. Since all nuclides are at normal - levels there is no indication of an effect on vegetaion from the operations of CNS.

L. SHORELINE SEDIMENT STATION 28 . Shoreline sediment samples were collected in the spring and fall from Station 28,1.8 miles,150 degrees downstrem of the release point of CNS. They were analyzed for gamma emitters by means of a high resolution gamma spectrometer. In the samples collected the naturally occurring isotopet , Be-7, K-40, Ra-226 and Th-228 were detected at normal environmental leveis. Cesium-137, a fission product, was detected at an average level of 0.085 pCi/gm, dry. For the samples col.iected in the fall the naturally occurring isotopes were detected at about the same level as in the spring. Cesiun-137 was found at a level of 0.097 pCi/gm dry. Manganese-54, an activation product was detected at a level of .020 pCi/gm, dry in the spring smple. Cob al t-60, another activation product, was detected in the fall sample at a level of 0.019 pC1/gm, dry. Presented in Figure L-1 are the plots of the radionuclides K-40, I-131, Cs-134 and Cs-137 in shoreline sediment for 1985, 1986 and 1987. Shoreline ~ sediment was first monitored in 1985. No detections of I-131 nor Cs-134 were seen and K-40 was at a normal environmental level. The Cs-137 was at a low - , level which is found in many areas and media. Since sediment tends to trap ' and retain any elements in the water pathway, it acts as a good indicator of the effects on the water pathway of any reactor effluents. 98

APPENDIX A LAND USE CENSUS D 6 I O e T
i . LAND USE CENSUS l July 15, 1987 3 0-3 Miles ! Cooper Nuclear Station (CNS) Radiological Effluent Technical 4
. Specifications require an annual land use census. This census identifies the location of the nearest garden that is greater than 500 square feet in area and yields edible leafy vegetables, the location of the nearest milk animal, and the location of the nearest resident in each of the 16 meteorological sectors within 3 miles of CNS.
No changes have occurred in the nearest resident category since the 1986 land use census. The nearest resident to CNS is in Sector Q, 0.9 miles from CNS. The number of gardens found in 1987 was about the sama as the number found in 1986. The 1987 census revealed no gardens within
- 3. miles of CNS in one sector (Sectors N) that had a garden in 1986. Sector Q has a garden within 3 miles of CNS l'n 1987 but did not have a garden in 1986. The nearest garden to CNS in
- Sector L in 1987 is a different garden than the nearest garden found in 1986. Both the 1987 and 1986 nearest garden in Sector L were 2.2 miles from CNS but the 1986 nearest garden was 227 degrees from CNS while the 1987 garden is 220 degrees from CNS.
No milk animals were found within 3 miles of CNS in 1987. This *
. was also the case in 1986.

US EPA CROSS-CHECX PROGRAM 1987 (Cont.) Collectica Teledyne Date Media Nuclide EPA-Results(a) Isotopes Results(b) Notes: ( a) EPA Results-Expected laboratory precision (1 sigma). Units are pCi/t for water, and milk except K is in mg/t. Units are total.pCi for air particulate filters. (b) Teledyne Results - Average one sigma. Units are pCi/f for water and milk except X is in mg/t. Units are total pCi for air particulate filters. (c) Units for food analysis are pCi/kg except K-40 which is mg/kg. (d) No aerosol solution was added to the planchets in the final stages of preparation in order to create a more efficient counting geometry. The technicians in the alpha beta laboratory have been instructed to add the aerosol in accordance with Procedure PRO-031-1. -
. (e) No reason could be ascertained for the high result for Zn-65. Previous results had a normalized deviation from the known of -0.34 (10/10/86) , and 0.58 (06/06/86). Therefore this does not. appear to be a trend.
Further cross-checks will be studied for any problems.
. ( f) A new radiochemical method is being developed for this analysis which should give more accurate results.
(g) The previous two EPA beta results are 6 percent low, and our in-house beta spikes are low by about the same percentage. Dr. H. Jeter will re-train the analysts in transferring all sample residue into the planchets. (h) The reported high result was due to small aliquot available for the Sr-90 analysis. Inadvertently a larger aliquot was used for another analysis leaving 40% of the normal volume for Sr-90. Additionally, the narrow acceptance limits defined by EPA is particularly difficult to meet. For this analysis 63% of the participants were beyond the t 3 sigma limit. (i) The low result is attributed to the application of the resin method rather than the hydroxide method to this analysis. The resin method is inefficient at absorbing protien-bound iodine thus leading to low results. The results obtained by GeLi were higher. (j) The Cs-137 results in EPA Foods have typically been biased high. We are in the process of performing our annual calibrations. We are using a new
/cersham mixed gamma standard rather than the most recently prepared NSS standard which is now several years old. Based on preliminary results the three Cs-137 values would be 52.1, 50.3, and 50.9, which average 51.1.

(k) Erroneously high electrode reading of stable iodide in sanple (possibly because of interfering species such as S--) leading to erroneously low chemical yields. After repeat.ing the electrode reading, the calculated average I-131 is 49.6 pCi/t. Technicians have been made aware to ba suspicious of high electrode readings. When unusually high readings occur samples will be diluted and/or oxidized and remeasured. (1) A new Ra-228 analytical procedure is being evaluated as a corrective action to the variability of results with current method. TI No. 12115 and TI No.12116 (there was not sufficient ssnple for a third analysis) were also analyzed by the new procedure with results of 5.9 to 7.0 pCi/2. - The new method will be used for the next Radium in Water Cross-check samples. (m) The data for the Cr-51 results were reviewed. The detector ef ficienciess - appear to be correct. The other five isotopes measured in this sanple were within two standard deviations indicating there is no systematic - error. Chromium-51 is difficult to measure at this activity level . because of the low branching intensity of the gamma ray and being in the high background region of the spectrum since Cr-51 has a low energy ray. - (n) An investigation is being conducted and the results will be available shortly.

T TELEDYNE ' ISOTOPES APPENDIX C . STATISTICAL NOTES
- 1. Each activity is reported in one of two forms:
x i s or
<L, where x = value of measurement; s = probable countin,g error at the 95%
confidence level (2e error); L = detection limit based on 4.66e error for background sample.
- 2. All activities are corrected to collection time.
- 3. Computation of means and standard deviations:
(a) In any statistical table, the values are entered as . x s or <L where EX ; _x = s ampl e me an = n n = number of data points averaged; 2 s = sample standard deviation = n-1 if n>1;
= 2e uncertainty if n = 1. ,
(b) For gross beta and gross alpha results in air particulates, averaging includes values which are less than the lower limits of detection. The detection limit is used as the sanple activity in these cases. (c) In all other cases, if all values in an averaging group are below detection limits, the highest of the detection limits is reported as a "less than"value without an associated standard deviation. If some values are above C-1
l T TELEDYNE ISOTOPES detection limits and some are below, then: (1) The mean and standard deviation of the detectable result equal to or greater than the highest "less than" value are reported, and the number detectable is listed in parentheses; if there is only one detectable result the 2e error is reported instead of the standard deviation; and (2) the highest nondetectable result is reported as a "less than" value, and the number nondetectable and the number detectable but below the "less than" value are listed in parentheses. , (d) Means and standard deviation are reported on a quarterly basis except for air particulate and airborne iodine data which are reported monthly. For ' air particulate and charcoal filters, data for samples collected on the 1st, ' ' 2nd, and 3rd day of a month are assigned to the previous month. (e) Cunulative means and standard deviations shown to the right and at the bottom of air particulate statistical tables are computed using the formulas shown in (a) above for all samples in the averaging group. They are not averages of the means and standard deviations shown in the main body of the table. (f) In rounding off, numbers followed by a 5 or higher digit are rounded upwards. n C-2

*LLD - lower liniit of detection based on 4.66s ; &whe're sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute)*. The LLD is at counting time and must be in the absence of any radionuclides is the sample. In calculating the LLD for a radionuclide determined by gamma-ray l spectrometry, the background shall include the typical contributions of other radio-nuclides normally present in the samples (e.g.. potassium-40 in milk samples).
Occasionally background fluctuations, unavoidably small sample mazes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLb's unachievable, la such cases, the contributing factors will be identified and described in the Environmental Radiation Monitoring Program Annual Report. Note: All LLD's which we require are listed in th16 table for Ce(L1) Camma Spectorscopy. If any nuclide is detested. At shall be reported quantitatively whether or not it is.one of the 20 nuclides listed above.
