AIR PARTICULATC SAMPLCS - GROSS BETA AND GROSS ALPHA (See Tables A A-4, B B-4 STATIONS 01 to 10 Air particulates were collected continuously on membrane filters which w3rc changed weekly at Stations 01 through 10.
The filters were shipped to Teledyne Isotopes and analyzed for gross beta and gross alpha.
They were composited for each station quarterly and monitored for gamma activity (See Tchles 0-1 and D-2).
The gross beta activity for each quarter since July 1980 is summ6rized below:
1980 Third Quarter 0.029 pCi/Cu. M.
October 16 Chinese Atmospheric Nuclear Tests fourth Quarter 0.053 pCi/Cu. M.
1981 First Quarter 0.130 pCi/Cu. M.
Second Quarter 0.260 pCi/Cu. M.
Third Quarter 0.053 pCi/Cu. M.
Fourth Quarter 0.033 pCi/Co. M.
It is indicated by these averages that the level of gross beta activity rose sharply af ter the Chinese atmospheric nuclear tests of October 16, 1980.
The activity reached a high in the second quarter of 1981 and is now tapering off to a level similar to that before the tests.
This trend has been observed in may areas of the United States.
It may be concluded that this increased activity was caused by follout from the Chinese nuclear tests and not from the operations of CNS.
The gross alpha activity (Tables B-1 through B-4) continues low and close to the limits of detection.
This low gross alpha activity is probably due to alpha emitters found in soil and cosmogenic radiation.-
One air particulate filter for the second quarter was not included in the averagcc because the blue paper was not removed and r.O air was drawn through the filter.

STATIONS 01 to 10 Charcoal filtero used in series with air particulate filters were col-lected weekly during 1981 at station 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 for all 10 stations.
No airborne I-131 was detected; all results were at or below the minimum level of detection.
The fact that no airborne I-131 was detected in charcoal filters during 1981 supports the fact that the ince ase in beta activity, summarized in Parts A and D was due to the Chinese stmospheric nuclear tests and not from any releases by CNS.

STATIONS 01 to 10 h

Weekly Air Particulate filters were composited for each station for o quarterly gamma spectral analysis during the four quarters of 1981.
I During the first two quarters there were detections of the fission product nuclides Zr-95, Ru-103, Ru-106, Cs-137, Ce-141 and Ce-144 at almost all 10 stations.
These detections reached a peak in the second quarter of 1981 dropping off considerably in the third quarter and entirely in the fourth These nuclides are a continuing trend from the fourth quarter of 1980 quarter.
and occurred after the Chinese atmospheric nuclear tests of October 16, 1980.
This some trend was noted in other areas of the United States which lends support to the conclusion that they are due to the Chinese nuclear test.
There were two detections of Co-60 at station 01 and 02 during the second quarter and eight detections of Mn-54.
Upon further testing of the composite of Station 01, it was found that the detection of Co-60 was for the period June 22 through June 29.
This correlates with the period of maximum fallout from the Chinese nuclear tests.
The detections of Mn-54 were low being slightly above detection level. Berillium-7, which is naturally occurring, was detected at all stations at about the same level as previously.
The average of gross beta measurements for all stations reached a maximum of 0.260 pCi/Cu M. during the second quarter of 1981 and fell to a level of 0.033 pCi/Cu. M. by the end of 1981. The 1-131 measured in charcoal filters in series with the air particulate filter remained below the limit of detection.
There was no correlation between the level of activity and the stations close to the plant.
This would tend to support the conclusion that the nuclides detected were from the Chinese test of October 16, 1980 and were not associated with the operations of CNS.

EGGS (See Tables E1, E2)
STATIONS 42, 51, 67, 76 Egg samples were collected quarterly from four locations and analyzed for elemental calcium, gross beta, Sr-89, Sr-90 and gamma emitters. The gross beta measured 1.5 pCi per gram, wet, which was accounted for largely by the natural-ly occurring, terrestrial isotope K-40.
No other gamma emitters were measured above the minimum level of detection.
There were no detections of Sr-89 and 3 detections of Sr-90 in 16 samples at a level of 0.0017 pCi per gram, wet, which
'is below the minimum level of detection.
The level of elemental calcium in 16 samples was 0.14 mg per gram which is similar to the levels of previous years.
There is no evidence of an effect from the operation of CNS on egg samples.

FEED AND FORAGE - BEEF PRODUCERS (See Tables F-1 and F-2)
STATIONS 64, 65, 67, 68, 71, 76 feed and forage samples were collected monthly from beef producers at six stations and radioassayed for gamma emitters During peak pasture season monthly composite was made of the weekly samples (June through September) a received and also measured for gamma activity.
Bery11ium-7, of cosmic origin, was detected in 44 of 79 samples and the terrestrial nuclide K-40 was detected in 87 of 87 samples at the levels encountered in the past.
There were 2 detections of the neutron activation product Mn-54; one at station 68, 3.4 miles from the plant in the June composite and one at station 64, 2.25 miles from the plant in the July composite.
Both of these were slightly above the minimum detection level.
Manganese-54 has been seen in air particulate filters and was probably due to the fallout of nuclear debris.
The fission product nuclides Zr-95, Ru-103, Ru-106, Cs-137, Ce-141 and Cc-144 were detected in several samples (See Table F-1).
These reached a peak in the second and third quarters and tapered off to a lower level in the fourth
- quarter, lhe incidence of these fission nuclides was not at any one particular station nor was it related to distance from the plant.
These same nuclides and the same trend to peak in the second and third quarters was noted in the composite of air particulate filters (See Section D).
This suggests that the probable source of these nuclides is atmospheric fallout from the Chinese nuclear tests and is not related to the operations of CNS.

Garden crops and apples were radioassayed once during the year at harvest Detectable for gross beta, St-89, Sr-90, elemental calcium and gamma emitters.
concentrations of gross beta, elemental calcium and K-40 were monitored in each sample. and are the usual elements measured in food and garden crops.
The results monitored during 1981 duplicate measurements conducted during previous
.yurs.
No Sr-90 was detected in apples.
Strontium-90 vas detected in two of three garden vegetable samples at an average level of 0.0016 pCi/gm, wet, which is below the minimum level of detection.
There were no gamma emitters above the minimum levels of detection except K-40 as cited above.
It may be con-cluded that there was no detectable effect on food and garden crops from the operations of CNS.

STATIONS 61, 74 (Nearest Milk Producers) 3.
STATIONS 42, 73, 75 (Commercial Milk Producers) feed and forage was collected from milk producers nearest the plant Feed and quarterly from two stations and monthly during peak pasture season.
forage from commercial milk producers was collected quarterly from three stations.
These samples were monitored for Sr-89, Sr-90, elemental calcium and gamma emitting nuclides.
Sr-90 and elemental calcium were detected in these samples at levels similar to the levels monitored in 1973 through 1980.
There were several detect ions of Sr-09 at both the nearest stations and at'the commercial stations at approximately the same level. Sr-89 was detected in air particulate filt.ers in some ares of the United States indicating that this was r
the result of ' fallout from previous nuclear tests especially those of October 16, 1980.
The naturally occurring nuclides Be-7, K-40, Ra-226 and Th-228 were detected at the Icycls seen in camples in previous years.
There was one detection of the activat ion corrosion product Mn-54 at station 73 which is 10 miles from the plant.
This was slightly above the detection level and has been seen in air particulate filters also, indicating that it was probably from
. fallout.
The fission related products Zr-95, Ru-103, Cs-137, Cc-141 and Cc-144 occurred in several samples reaching a peak in the third quarter and tapering off to zero in the fourth quarter. These nuclides were seen in samples equally at stations farthest from the plant as well as those nearest to it.
This is 1
the same trend seen in feed and forage from beef producers and in air partic-ulate filters.
This gives further support to the conclusion that these nuclides were due to follout from the Chinese atmospheric nuclear tests on-October 16, 1980.
Thus it has been established that no nuclides which are related to CNS could be ingested by cows from feed and forage and there is no doue impact to the populat ion.

gnd range to those measured in the previous years of wet.
Gross beta activity measured an average of 11.0+-0.9 pCi per gram, This was largely due to K-40, the naturally occurring, terrestrial nuclide.
Strontium-90 was detected in 3 of 8 samples at an average of 0.012 pCi/gm, wet, which is below the minimum level of detection. The elemental calcium level was similar to that of other years at 0.52 mg per gram.
From this mcnitoring data it may be concluded that there is na effect on food-and feed crops from the cperations of CNS.

detections of Sr-89.-
All of the gamma emitters were at or below the minimum level of detection except -K-40, a naturally occurring isotope, which was at
-the same level as previous years.-
There was no significant difference between the fish caught at station 28 downstream from the discharge point and that caught at station 35 upstream from discharge point.
Since no change has occurred in levels of activity in the isotopes monitored since 1975 it can be concluded that the operations of CNS have had no effect on fish samples.

STAT 10NS 61, 74 (NEAREST PRODUCERS)
Hilk samples from commercial producers were collected quarterly from 3 stations and monitored for 1-131, Sr-09, Sr-90, elemental calcium and gamma emitters. Hilk samples from nearest producers were collected from two stations monthly and monitored for I-131, Sr-89, Sr-90, elemental calcium and gamma emitters.
During peak pasture season weekly samples were collected and moni-tored for 1-131.
A monthly sample was composited and monitored for the same analytes os the monthly sample.
There were no detections of 1-131 or Sr-09 in milk from either the com-mercial producers or the nearest producers.
St-90 was detected in 36 of 39 samples during the four quarters at levels slightly below those of 1900.
Elemental calcium levels remained approximately the same.
Naturally occurring K-40 remained at the same levels as previous years.
There were no other detect ions of gamma emitting nuclides oxcept for one detection of naturally occurring Th-228 in the first quarter at n very low level.
Thus we conclude that the operations of CNS had no effect on the milk from commercial nor from nearest producers and thus no dose impact on the population.

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 radio-nuclides.
Station 11 is 0.15 miles from the plant and station 47 is 25.75 miles from, the plant.
There was no gross alpha activity detected and no detections of gamma emitters above the minimum level of detection.
The gross The tritium level beta activity was statistically the same as in past years.
overaged 180 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 station.
It may be concluded that there is no impact. from the operations of CNS on the environ-ment as shown by measurements of radionuclides in groundwater.

RIVER WATER (See Table P-1 and P-2)
STATIONS 12,13,28 River water was collected monthly and monitored for gross beta and gross alpha, suspended and dissolved, Sr-89 and Sr-90.
A quarterly composite was measured for gamma emitters and tritium.
All measurements during 1981 were in agreement with those of the period 1973 through 1980. There were no detections of Sr-89 or Sr-90 above the minimum level of detection.
Gross beta and gross alpha readings, suspended and dissolved, were at normal environmental levels for river water.
There were no detections of gamma emitters.
These measurements indicate that the river water samples monitored during 1981 cont ained no detectable CNS plant radionuclides.
Additional verificalion of no detectable releases is the low range of H-3 activity which was from 200 to 520 pCi/ liter.

TTELEDYNE ISOTOPES ANIMALS - RABBITS (See Tables 0-1 and Q-2)
Q.
STATION 28 and 35 Rabbit sampics were collected from stations 28 and 35 in the fall of 1981.
The femur was analyzed for Sr-89 and Sr-90, the thyroid gland for I-131 and the Strontium 90 was detected in four of four samples muscle for gamma emitters.
analyzed at a level slightly lower than previous years.
Iodine-131 analyses were below the minimum level of detection.
There were no gamma emitters detected except for naturally occurring K-40 shich was at the same level as in the previous years from 1977 through 1980.
Cesium -137 was at or below the lower limit of detection.
The result, P the monitoring of rabbit samples indicate that no nuclear in animal plant effects resulting from the operations of CNS were detectable life.

AQUAllC VEGETATION (See Tables R1 and R2)
STATION 12, 13,28 Aquatic vegetation was scheduled to be collected semiannually and measured for gross beta, Sr-89, Sr-90 and gamma emitters. Samples were collected during the fall of 1981 at stations 12 and 28.
No sample was available et station
- 13. No samples were collected during the summer of 1981 at any of the three stations because of dry conditions and lack of growth.
No samplec had been obtained in 1977 and 1979 for the same reasons.
The gross beta activity was slightly higher than in the past at 3.8 pCi/gm, wet.
There were no detections of Sr-89 or Sr-90.
Potassium-40 was detected in one sample at the same level as in previous years. Manganese-54, Co-58 and Co-60, which are neutron activation products, were detected in both samples collected; Mn-54 at 0.35 pCi/gn, wet, Co-58 at 0.52 pCi/gm, wet, and Co-60 at 0.77 pCi/gm wet.
This is slightly higher than the levels detected in 1980.
Since the sampling locations are in close prox-imity (Station 12 is within the site boundaries and Station 28 is within three miles downstream of the discharge point), it is assumed that these nuclides originated from CNS.
No other gamma emitters were detected above the minimum level of detection.

SOIL (See Tables S1 and S2)
STATIONS 2,3,4,5,6,7,8,9,10 Soil samples, which are collected every three years, were collected on September 10, 1981.
Samples were analyzed for Sr-90 and gamma emitting isotopes.
Strontium-90 was detected in 9 of 11 samples at a level of 0.16 pCi/gm, dry.
This is very close to th levels detected in 1975 and 1978.
Among the gamma emitters K-40 remained at the previous level of 17.0 pCi/gm, dry.
Radium-226 and Thorium-228 levels also remained constant.
Trace levels of Cs-137 were detected in eleven of eleven samples and of Zr-95 in one of eleven samples.
These nuclides were also detected in air particulate samples and are probably due to fallout from the Chinese nuclear atomspheric weapons tests of October 16, 1980.
There is no indication of a plant ef fect.

T.
STATIONS 01-10,15,18,22,44,58,59 Ambient radiation was monitored at 16 locations within a 10 mile radius of CNS and collected quarterly.
The quarterly averages of ambient net gamma radiation ranged from 19.4+-4.4 milliroentgen / quarter to 21.2+-5.5 milli-Roentgen / quarter.
The highest exposure during each of the four quarters at station 01 (0.1 mile, 225 degrees) and averaged 37.1+-5.6 mR/ quarter.
The lowest exposure was at station 03 (2.5 miles, 338 degrees) and averaged 17.1 mR/ quarter.
These exposures were considerably below the 125 millirems per quarter i
The relationship between specified in 10 CFR 20.105 for an unrestricted area.
mil 11 Roentgen (mR) and millirems (mr) is approximately one for the exposure conditions encountered. No plant effect from CNS was indicated.
