SUMMARY
~
The Radiation Environmental Monitoring Program (REMP) required by the U.S.
Nuclear Regulatory Commission (NRC) Technical Specifications for the Monticello Nuclear Generating Plant is described.
Results for 1982 are summarized and discussed.
Results obtained for gross beta in airborne particulates collected during the first quarter of 1982 show a moderate effect of fallout from atmospheric nuclear detonation of a 200 kiloton to 1 megaton range device on 16 October 1980.
Presence of other fission products, mostly strontium-90 and cesium-137 in some of the sampling media indicates a long range effect on the environment from fallout resulting from previous atmospheric nuclear tests.
No effect on the environment due to the operation of the Monticello Generating Plant is indicated.

HAZLETON CNVIRONMENTAL SCIENCES 3.0 RADIATION ENVIRONMENTAL MONITORING PROGRAM (REMP) 3.1 Program Design and Data Interpretation The purpose of the Radiation Environmental Monitoring Program (REMP) at the Monticello Nuclear Generating Plant is to assess the impact of the
~
Plant on its environment.
For this purpose, samples are collected from the air, terrestrial, and aquatic environments and analyzed for radio-active content.
In addition, ambient gamma radiation levels are monitored by thermoluminescent dosimeters (TLDs).
Sources of environmental radiation include the following:
(1) natural background radiation arising from cosmic rays and primordial radionuclides; (2) fallout from atmospheric nuclear detonations; (3) releases from nuclear power plants.
In interpreting the data, effects due to the Plant must be distinguished from those due to other sources.
A major interpretive aid in assessment of these effects is the design of the monitoring program at the Monticello Plant which is based on the indicator-control concept.
Most types of samples are collected both at indicator locations (nearby, downwind, or downstream) ani at control locations (distant, upwind, or upstream).
A plant effect w)uld be indi-cated if the radiation level at an indicator location was significantly larger than that at the control location. The difference would have to be l
greater than could be accounted for by typical fluctuations in radiation l
levels arising from other sources.
i An additional interpretive technique involves analyses for specific radio-nuclides present in environmental samples collected from the Plant site.
The Plant's monitoring program includes analyses for tritium, strontium-89, strontium-90, and iodine-131.
Most samples are also analyzed for gamma-emitting isotopes with results for the following groups quantified:
l s
3 l
T HAZl.ETON CNVIRONMZNTAI. SCl2NCES zirconium-95, cesium-137, cerium-144, beryllium-7, and potassium-40.
The first three gamma-emitting isotopes were selected as radiological impact indicators because of the different characteristic proportions in which they appear in the fission product mix produced by a nuclear reactor and that produced by a nuclear detonation. Each of the three isotopes is pro-duced in roughly equivalent amounts by a reactor:
each constitutes about 10% of the total activity of fission products 10 days after reactor shut-down. On the other hand,10 days after a nuclear explosion, the contribu-tions of zirconium-95, cerium-144, and cesium-137 to the activity of the resulting debris are in the approximate ratio 4:1:0.03 (Eisenbud,1963).
Beryllium-7 is of cosmogenic origin and potassium-40 is a naturally-occurring isotope.
They were chosen as calibration monitors and should not be considered as radiological impact indicators.
The other group quantified consists of niobium-95, ruthenium-103 and -106, cesium-134, barium-lanthanum-140, and ceri um-141.
These isotopes are released in small quantities by nuclear power plants, but to date their major source of injection into the general environment has been atmos-pheric nuclear testing.
Nuclides of the final group, manganese-54, cobalt-58 and -60, and zinc-65, are activation products and arise from activation of corrosion products.
They are typical components of nuclear power plant's effluents, but are not produced in significant quantities by nuclear detonations.
Other means of distinguishing sources of environmental radiation can be employed in interpreting the data.
Current radiation levels car be compared with previous levels, including those measured before the plant became operational.
Results of the Plant's Monitoring Program can be related to those obtained in other parts of the world.
Finally, results can be related to events known to cause elevated levels of radiation in the environment, e.g., atmospheric nuclear detonations.
3.2 Program Description The sampling and analysis schedule for the Radiation Environmental Moni-toring Program (REMP) at the Monticello Plant is summarized in Table 5.1 and briefly reviewed below. Table 5.2 defines the sampling location codes used in Table 5.1 and specifies for each location its type (indicator or control) and its distance, direction, and sector relative to the reactor site.
To assure that sar:pling is carried out in a reproducible manner, detailed sampling procedures have been prescribed.(Hazleton Environmental Sciences, 1982).
To monitor the air environment, airborne particulates are collected on membrane filters by continuous pumping at seven locations. Also, airborne iodine is collected by continuous pumping through charcoal filters at four of these locations. Filters are changed and counted weekly.
4
HAZLETON ENVIRONMENTAL SCIENCES Particulate filters are analyzed for gross beta activity and charcoal filters for iodine-131.
A monthly composite of all particulate filters is gamma-scanned on a Ge(Li) detector.
Five of the seven locations are o
indicators, and two are controls (M-1 and M-2).
One of the indicators (M-6) is located in the geographical sector expected to be most suscep-tible to any atmospheric emissions from the Plant (highest X/Q sector).
Ambient gamma radiation is monitored at the same seven locations using CaF :Mn thermoluminescent dosimeters (TLDs).
The sensors are placed 2
in pairs at each location and are collected and measured quarterly.
In addition, as a " Lessons Learned" commitment, ambient gamma radiation is
~
monitored at thirty-seven (37) special locations using three (3) LiF2 chips for each location:
fourteen (14) in an inner ring in the general area of the site boundary, sixteen (16) in the outer ring within 4-5 mi radius, six (6) at special interest locations and one control location, 11.5 mi distant from the plant. They are replaced and measured quarterly.
Also, a complete emergency set of TLDs for all locations, including seven airborne particulate locations, is placed in the field at the same time as regular sets.
The emergency set is returned to HES quarterly for anneal-ing and repackaging.
Milk samples are collected monthly from five fanns (four indicator and one control).
All samples are analyzed for iodine-131.
In addition, samples from the control location (M-10, Kirchenbauer) and the highest X/Q location (M-18, Olson) are analyzed for strontium-89, strontium-90 and for gamma-emitting isotopes.
Natural vegetation (such as grass) is collected semi-annually from three locations (including the highest X/Q milk location and the milk control l
location).
- Samples are analyzed for gamma-emitting isotopes including iodine-131.
l l
Leafy green vegetables, collected annually from the garden nearest to the Plant and a control location, are analyzed for iodine-131.
Corn is l
collected annually from the higher X/Q farm and a control location and analyzed for gamma-emitting isotopes.
Potatoes are collected annually from a farm irrigated with downstream river water and a control location, and are analyzed for gamma-emitting isotopes.
l The terrestrial environment is also monitored by collection of well water (quarterly), wildlife (semi-annually) and' topsoil (every three years).
The latest collection of soil was in 1982.
5 o
HAZLETON ENVIRONMFNTA.L SCIENCES River water is collected weekly at two locations, one upstream of the Plant and one downstream.
Monthly composites are analyzed for gamma-emitting isotopes. Quarterly composites are analyzed for tritium.
Drinking water is collected weekly from the City of Minneapolis water supply, which is taken from the Mississippi River downstream of the Plant. Monthly composites are analyzed for gross beta activity and gamma-emitting isotopes.
Quarterly composites are analyzed for tritium, stron-tium-89, and strontium-90.
The aquatic environment is also monitored by semi-annual upstream and
~
downstream collections of fish, algae or aquatic insects, aquatic veg-etation, and bottom sediments.
Shoreline sediment is collected semi-annually.
3.3 Program Execution The Program was executed as described in the preceding section with the following exceptions:
(1) There were no TLD data for the third quarter,1982, for locations M-10A, M-11A, M-12A because they were lost in the field (vandalized).
(2) Algae or aquatic insects and aquatic vegetation were not collected in the fall of 1982 from locations M-8 (Upstream) and M-9 (Down-stream) because the river was too high.
Deviations from the program are summarized in Table 5.3.
3.4 Laboratory Procedures All strontium-89, strontium-90, and iodine-131 analyses in milk were made using a sensitive radiochemical procedure which involves separation of the element of interest by use of an ion-exchange resin and subsequent beta counting.
All gamma-spectroscopic analyses were perfonned with a Ge(Li) detector.
Levels of fodine-131 in cabbage and natural vegetation were determined by Ge(Li) spectrometry.
Levels of airborne iodine-131 in charcoal samples were measured by Ge(Li) spectrometry.

HAzLETON ENVIRONMENTAL SCIENCES 4.0 RESULTS AND DISCUSSION All of-the scheduled collections and analyses were made except those listed in Table 5.3.
All results are summarized in Table 5.4 in a format recommended by the Nuclear
~
Regulatory Commission in Regulatory Guide 4.8.
For each type of analysis of each sampled medium, this table lists the mean and range for all indicator locations and for all control locations.
The locations with the highest mean and range are also shown.
j 4.1 The Effect of Chinese Atmospheric Nuclear Detonation There were no reported atmospheric nuclear tests in 1982.
The last reported test was conducted by the People's Republic of China on 16 October 1980.
The reported yield was in the 200 kiloton to 1 megaton range.
There was a moderate residual effect of this test on the gross beta levels in airborne particulates.
The annual mean gross beta activity was about four times lower than in 1981.
The highest mean activity was reached in the month of January and in the first quarter and then by the end of 1982 declined steadily to the level observed in 1980.
4.2 Program Findings A number of program findings reflect effects of the latest Chinese and previous worldwide atmospheric nuclear tests.
The chief environmental indicators of a recent test effects were airborne particulates.
The residual effect of previous nuclear tests was detected in some of the milk, wildlife, natural vegetation, periphyton, bottom sediments, and soil samples (radiostrontium and cesium-137).
Ambient Radiation (TLDs)
At seven regular air sampling locations, indicator TLDs averaged 13.6 mR/91 days and control TLDs averaged 13.7 mR/91 days.
The location with the highest mean (15.1 mR/91 days) was location M-7, 2.7 mi SE of the Plant.
8
HAZLETON ENVIRONMENTAL SCIENCES The means at special locations were similar to those measured at regular locations and ranged from 12.3 mR/91 days for,the inner ring to 12.6 mR/91 days for the outer ring and special interest areas.
The differ-ences are not statistically significant.
The dose rates observed were similar to those observed in 1978, 1979, 1980, and 1981. No Plant effect on ambient gamma radiation was indicated.
Air Particulates The average annual gross beta activity in airborne particulates was essentially identical (t indicator locations (0.027 pCi/m3) and control locations (0.026 pCi/m3) and was about four times loger than in 1981 3
(0.113 pCi/m )and about the same as in 1980 (0.032 pCi/m3).
The decrease in the activity is attributable to the cleansing of the atmosphere from radioactive debris produced by the nuclear test conducted on 16 October 1980 The highest averages for gross beta were for the month of January and the first quarter, then decreased gradually to the 1980 level by the end of the year.
The elevated activity in January and the first quarter was due to residual fallout from the nuclear test conducted 16 October 1980. The spring peak, which usually is observed in April - May (2nd quarter) was somewhat obscured by the elevated activity during the first quarter.
This peak has been observed almost annually (1976,1979, and 1980 were exceptions) for many years (Wilson et al.,1969).
The spring peak has been attributed to fallout of nuclides from the stratosphere (Gold et al.,
1964).
It was more pronounced in 1981 because of the addition of radio-active debris from the latest nuclear test.
The spring peak in 1982 was somewhat obscured by higher than normal activity in January and the first quarter of 1982.
Two pieces of evidence indicate conclusively that the elevated observed activity during the first quarter was not attributable to the Plant.
In the first place, elevated activity of similar size occurred simultaneously at both the indicator and control locations.
Secondly, an identical l
pattern was observed at the Prairie Island Nuclear Generating Plant, l
about 100 miles distant from the Monticello Generating Plant (Northern i
States Power Company,1983).
Except for beryllium-7, all other gamma-emitting isotopes were below their respective LLD levels.
None of the activities detected were attributable to the Plant operation.

HAZLETON ENVIRONMENTAL. SCIENCES Airborne Iodine Airborne iodine-131 results were below the detection limit of 0.07 pCi/m3 in all samples. Thus. there was no indication of a Plant effect.
Milk Iodine-131 results were below the detection limit of 0.25 pCi/l in all s ampl es.
Strontium-90 results averaged slightly higher at indicator location (M-18).
The annual means were 6.3 pCi/l and 5.3 pCi/1 at indicator and control locations respectively.
The difference is not statistically significant. All results were in the range 4.3 - 10.5 pCi/l; a range consistent with 1976, 1977, 1978, 1979, 1980, and 1981 observations at Monticello.
Strontium-90 levels in this range are attributable to world-wide fallout from previous atmospheric nuclear tests and reflect the long half-life (28.64 yrs.) of this isotope. Cesium-137 results were below the LLD level of 15 pCi/1 in all samples.
Cesium-137 is also a long-lived component (with a half-life of 30.24 years) of worldwide fallout and is found in the environment in trace amounts.
Finally, all strontium-89 results in 1982, except one, were less than 2.0 pCi/1, in agreement with 1976, 1977, 1978, 1979, 1980, and 1981 measurements.
The detected activ-ity was 5.4 pCi/l in a control sample.
No significant changes were seen in strontium-90 levels which were similar to those observed in 1978, 1979, 1980, and 1981.
This absence of an effect is consistent with the low initial production of this isotope in nuclear explosions (Eisenbud, 1963).
Also no other gamma-emitting iso-topes, except potassium-40, were detected in any milk samples.
This is consistent with the finding of the National Center for Radiological Health that most radiocontaminants in feed do not find their way into milk due to the selective metabolism of the cow.
The common exceptions are radio-isotopes of potassium, cesium, strontium, barium, and iodine (National Center for Radiological Health, 1968).
In summary, the presence of strontium-90 in the milk data for 1982 is not due to the effects of Plant operation as explained above. but rather is the result of the long range residual effect of previous atmospheric nuclear tests.
River Water and Drinking Water Tritium was below the LLD level of 330 pCi/1 in all samples.
Strontium-89 and strontium-90 were below the detection limits of 2.3 pCi/1 and 1.4 pCi/l respectively in all drinking water samples.
Gross beta in Min-neapolis drir. king water averaged 2.9 pCi/l and was similar to the average 10
HAZLETON ENVIRONMENTAL. SCIENCES level observed in 1977 (3.4 pCi/1), in 1978 (3.8 pCi/1). in 1979 (3.4 pCi/1), in 1980 (3.2 pCi/1), and in 1981 (3.5 pCi/l).
Comparison with gross beta and strontium-90 data reported by EPA for Minneapolis drinking water samples collected in 1975, 1976, 1977, and 1978 indicates that concentrations of these nuclides are remaining f airly constant and are in,
the range of drinking water levels in other parts of the country (U.S.
Environmental Protection Agency, 1975,1976,1977,1978).
Gamma-emitting isotopes were below detection limits in all surface water samples.
There was no indication of a Plant effect.
Well Water The tritium level was below the LLD level of 330 pCi/1 in all samples.
All of the gamma scan results were below detection limits.
There was no indication of a Plant effect on the results.
Crops Corn and potatoes were collected in August and analyzed for gamma-emitting isotopes.
Cabbage and turnips were also collected in August and analyzed for iodine-131. All results except for potassium-40, were below detection limits. There was no indication of a Plant effect.
Small Game Animals Rabbits were collected in February, October. and November. Cesium-137 was detected in the flesh of two rabbits; in one rabbit collected at indicator location M-16 (0.11 pCi/g wet weight) and in one collected at control location M-17 (0.17 pCi/g wet weight). All other gamma-emitting isotopes, except potassium-40, were below their respective LLD's.
In all samples, potassium-40 results averaged 3.61 pCi/g wet weight in flesh and 4.98 pCi/g wet weight in liver. Thus, no Plant effect is indicated.
Natural Vegetation In natural vegetation, cesium-137 (0.09 pCi/g wet weight) was detected in one sample collected at control location M-10.
The level was similar to that observed at this location in 1980 (0.10 pCi/g wet weight) and in 1981 (0.13 pCi/g wet weight).
All other gamma emitting isotopes, except beryllium-7, which is constantly produced in the upper atmosphere by cosmic rays. and naturally-occuring potassium-40, were below their respec-tive LLD's. Thus, no Plant effect is indicated.
Topsoil In soil, strontium-90 was detected in all samples, and averaged 0.103 and 0.070 pCi/g dry weight in indicator and control samples. respectively.
Cesium-137 was also detected in all samples and averaged 0.377 pCi/g dry 11
HAZl.ETON ENVIRONMENTAR. SCIENCES weight at indicator locations and 0.916 pCi/g dry weight.
The only other gamma-emitting isotope detected was naturally-occuring potassium-40.
The mean activity of potassium-40 was identical at both indicator and control locations (12.8 pCi/g dry weight).
There was no indication of a plant effect.
Fish Fish samples were collected in June and September.
Flesh was separated from the bones and gamma scanned.
Potassium-40 was the only isotope detected and the results were similar in upstream and downstream samples (3.12 and 3.54 pCi/g wet weight, respectively).
There was no indication of a Plant effect.
Algae and Periphyton Two samples were collected in June.
Though there was a second scheduled collection in November. it was not done because the river was too high.
The samples were analyzed for strontium-89, strontium-90, and gamma-emitting isotopes.
Most of the isotopes were below detection limits.
Cesium-137 was detected in one upstream sample (0.28 pCi/g wet weight).
Strontium-89 was below the detection limit of 0.13 pCi/g wet weight in both samples.
Strontium-90 was detected in both samples and was slightly higher at the indicator location (0.134 pCi/g wet weight) than at the control location (0.094 pCi/g wet weight). Except for constantly produced beryllium-7 and naturally-occurring potassium-40, no other gamma-emitting isotopes were detected.
There was no indication of a Plant effect.
Aquatic Vegetation Aquatic vegetation was also collected in June.
The second scheduled collection for November was not done due to a high water level in the I
l river. The samples were analyzed for gamma-emitting isotopes. Except for l
naturally-occuring potassium-40, no other isotopes were detected.
No Plant effect was indicated.
Bottom and Shoreline Sediments Bottom and shoreline sediment collections were made in June and October, and analyzed for gamma-emitting isotopes.
Cesium-137 was detected in two bottom sediment samples one upstream and one downstream (0.16 pCi/g dry weight, average) and the activity was slightly lower than in two shoreline sediment samples (0.28 pCi/g dry weight, Montissippi Park),
indicating the influence of fallout deposition.
Similar levels of activ-ities and distribution were observed in 1978, 1979, 1980, and 1981. The only other gamma-emitting isotope detected was naturally-occuring potas-l sium-40. There was no indication of a Plant effect.

a GB = gross beta; GS = gamma scan.
LLD = nominal lower limit of detection based on 4.66 sigma error for.badgecund sample.
g Mean and range based upon detectable measurements only. Fraction of detectable m.casuranents at specified locations is indicated in parentheses (F).
d Locations are specified (1) by name and code (Table 2) and (2) dt=tance, direction; ar.d sector relative to reactor site.
e Nonroutine results are those which exceed ten times the control stttion values If no control station value is available, the result is considered nonroutine if it exceeds ten times the precperationas value for the location.
f Monthly composites from all locations were gamma scanned together. Thus the letation with the highest annual mean cannot be identified.

HAZLETON ENVIRONMENTAI. SCIENCES Appendix A Crosscheck Program Results The Nuclear Sciences Department of Hazleton Environmental Sciences has parti-cipated in interlaboratory comparison (crosscheck) programs since the formula-tion of its quality control program in December 1971.
These programs are operated by agencies which supply environmental-type samples (e.g.,
milk or water) containing concentrations of radionuclides known to the issuing agency but not to participant laboratories.
The purpose of such a program is to provide an independent check on the laboratory's analytical procedures and to alert it to any possible problems.
Participant laboratories measure the concentrations of specified radionuclides and report them to the issuing agency.
Several months later, the agency reports the known values to the participant laboratories and specifies control limits.
Results consistently higher or lower than the known valuet or outside the control limits indicate a need to check the instruments or procedures used.
The results in Table A-1 were obtained through participation in the environ-mental sample crosscheck program for milk and water samples Buring the period 1975 through 1982.
This program has been conducted by the U. S. Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, las Vegas, Nevada.
The results in Table A-2 were obtained for thermoluminescent dosineters (TLD's) during the period 1976, 1977, 1979, 1980, and 1981 through participation in the Second, Third, Fourth, and Fifth International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2.

where x = value of the measurement; s=2 counting uncertainty (corresponding to the 95% confidence level).
In cases where the activity is found to be below the lower limit of

Computation of Averages and Standard Deviations 4.1 A"erages and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standa'rd deviations. The averag'e x and standard are defined deviations of a set of n numbers x1, x2,... xn as follows:
x = f Ex EIx-xy2 K
s=
n-1 4.2 Values below the highest lower limit of detection are not included in the average.
4.3 If all of the values in the averaging group are less than the highest LLD, the highest LLO is reported.
4.4 If all but one of the values are less than the highest LLO, the single value x and associated two sigma error is reported.
4.5. In rounding off, the following rules are followed:
4.5.1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are kept unchanged. As an example,11.443 is rounded off to 11.44.
4.5.2 If the figure following those to be retained is greater than 5, the figure is dropped, and the last retained figure is raised by 1.
As an example. 11.446 is rounded off to 11.45.
4.5.3. If the figure following those to be retained is 5, and if there are no figures other than zeros beyond the five, the figure 5 is dropped, and the last-place figure retained is increased by one if it is an odd number or it is kept unchanged if an even number.
As an example,11.435 is rounded off to 11.44, while 11.425 is rounded off to 11.42.
