1.0 INTRODUCTION
This report summarizes and interprets results of the Radiation Environmental Monitoring Program (REMP) conducted by Hazleton Environmental Sciences at the Prairie Island Nuclear Generating Plant, Red Wing, Minnesota, during the period January - December, 1982. This program monitors the levels of radioactivity in the air, terrestrial, and aquatic environments in order to assess the impact of i
the plant on its surroundings.
1 Tabulations of the individual analyses made during the year are not included in this report.
These data are includeci in a reference document (Hazleton Envi-ronmental Sciences,1983) available at Northern States Power Company, Nuclear Support Services Department.
Prairie Island Nuclear Generating Plant is located on the Mississippi River in Goodhue County, Minnesota, and operated by Northern States Power Company.
The plant has two 550 MWe pressurized water reactors.
Unit 1 achieved initial criticality on 1 December 1973.
Commercial operation at full power began on 16 December 1973.
Unit 2 achieved initial criticality on 17 December 1974.
Commercial operation at full power began on 21 December 1974.

SUMMARY
The Radiation Environmental Monitoring Program (REMP) required by the U.S.
Nuclear Regulatory Commission (NRC) Technical Specifications for the Prairie l
Island Nuclear Generating Plant is described.
Results for 1982 are summarized i
and discussed.
i j
No effect on the environment due to the operation of the Prairie Island Nuclear
'j Generating Plant is indicated.
Results obtained for gross beta in airborne particulates collected during the first quarter of 1982 show a moderate effect of fallout from the 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.

3.1 Program Design and Data Interpretation 5'
The-purpose of the Radiation Environmental. Monitoring Program (REMP) at the Prairie Island 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 radioactive content.
In addition, ambient gamma radiation levels are monitored by thermoluminescent dosimeters (TLDs).
Sources of environmentel radiation include the following:
(1) natural background radiation arising from cosmic rays and i i primordial radionuclides;
'1 ti (2) fallout from atmospheric nuclear detonations; (3) releases from nuclear power plants.
i i
- i:
In interpreting the data, effects due to the Plant must be distinguished
,f.
from those due to other sources.
- i t
].
A major interpretive aid in assessment of these effects is the design of the monitoring program at the Prairie Island Plant which is based on the indicator-control concept.
Most types of samples are collected both at indicator locations (nearby, downwind, or downstream) and at control locations (distant, upwind, or upstream).
A plant effect would be indicated if the radiation level at an indicator location was signifi-cantly larger than that at the control location.
The difference would have to be greater than could be accounted for by typical fluctuations in radiation levels arising from other sources.
An additional interpretive technique involves analyses for specific radionuclides present in the enviornmental samples collected from the l
Plant site. The Plant's monitoring program includes analyses for tritium, j-strontium-89, strontium-90, and iodine-131.
Most samples are also analyzed for gamma-emitting isotopes with results for the following groups quantified:
zirconium-95, cesium-137, cerium-144, beryllium-7, and potassium-40.
The first three gamma-emitting isotopes were selected i~
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 produced in roughly equivalent amounts by a reactor:
each constitutes about 10% of the total activity of fission products 10 3
i HAZLETON ENVIRONMENTAL SCIENCES days after reactor shutdown.
On the other hand,10 days after a nuclear explosion, the contributions 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 radiological impact indicators.
The other group quantified consists of niobium-95, ruthenium-103, and 4
-106, cesium-134, barium-lanthanum-140, and cerium-141.
These isotopes are released in Jmall quantities by nuclear power plants, but to date their major source at injection into the general environment has been atmospheric 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 a 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 i
employed in interpreting the data.
Current radiation levels can be compared with previous levels, including those measured before the Plant i
became operational.
Results of the Plant's Monitoring Program can be i
related to those obtained in other parts of the world.
Finally, results o
can be related to events known to cause elevated levels of radiation in
>l, the environment, e.g., atmospheric nuclear detonations.
3.2 Program Description i
The sampling and analysis schedule for the environmental radiation monitoring program at Prairie Island 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 sampling is carried out in a reproducible manner, detailed sampling procedures have been prescribed (Hazleton Environmental Sciences Corporation, 1982).
To monitor the air environment, airborne particulates are collected on membrane filters by continuous pumping at four locations.
Also, airborne iodine is collected by continuous pumping through charcoal filters at three of these locations.
Filters are changed and counted weekly.
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.
Two of the four locations are indicators, and two are controls (P-1 and P-2).
One of the indicators (P-3) is located near the residence expected to be most susceptible to any atmospheric emissions from the Plant (highest X/Q residence).
4
~
HAZl.ETON ENVIRONMENTAR. SCIENCES Ambient gamma radiation is monitored at the same four air sampling locations using CaFg:Mn thermoluminescent dosimeters (TLD's).
The sensors are placed in pairs at each location and are collected and measured quarterly.
j' In addition, as a " Lessons Learned" commitment, ambient gamma radiation j
is monitored at thirty-two (32) special locations, using three (3) LiF2 j
chips mounted in the card:
ten (10) in an inner ring in the general area of the site boundary, fifteen (15) in the outer ring within 4-5 mi radius, six (6) at special interest locations and one control location, 11.1 mi distant from the plant. They are replaced and measured quarterly.
Also, a complete emergency set of TLDs for all locations, including four air sampling locations, is placed in the field at the same time as regular sets.
The emergency set is returned to the HES laboratory quarterly for annealing and repackaging.
i Milk samples are collected monthly from five fams (four indicator and i
one control).
All samples are analyzed for iodine-131.
In addition, samples from the control location (P-25, Kinneman Farm) and the highest X/Q location (P-14, Gustafson Farm) are analyzed for strontium-89, j
strontium-90, and for gamma-emitting isotopes.
I-For additional monitoring of the terrestrial environment, natural vegeta-tion (such as grass) is collected semi-annually from three locations (including the highest X/Q milk location P-14 and the milk control location P-25).
Samples are analyzed for gamma-emitting isotopes inclu-ding iodine-131.
Cabbage is collected annually from a garden nearest the Plant and a control location (P-25) and analy(zed for iodine-131.
Corn is collected annually from the highest X/Q fam P-14) and a control location (P-25) and analyzed for gamma-emitting isotopes.
Also, well water is collected quarterly and analyzed for tritium and gamma-emitting isotopes.
Finally, topsoil is collected every three years and analyzed for strontium
-90 and gamma-emitting isotopes.
The latest collection of soil was made in 1982.
Plant (P-5) and one downstream (y at two locations, one upstream of the River water is collected weekl P-6, Lock and Dam #3). Monthly composites are analyzed for gamma-emitting isotopes.
Quarterly composites are analyzed for tritium, strontium-89, and strontium-90.
Drinking water is collected weekly from the City of Red Wing well.
Monthly composites are analyzed for gross beta activity and gamma-emitting isotopes. Quarterly composites are analyzed for tritium.
The aquatic environment is also monitored by semi-annual upstream and downstream collections of fish, periphyton or macroinvertebrates, aquatic vegetation, and bottom sediments.
Shoreline sedment is collected semi-annually.

Havn WTON ENVIRONMENTAL. SCIENCES 3.3 Program Execution The Program was executed as described in the preceding section with the following exception; The TLD data for the third quarter of 1982 for location P-1 because the were lost in the field (vandalized).
-f 3.4 Laboratory Procedures l
All strontium-89, strontium-90, and iodine-131 analyses in milk were made l
by using a sensitive radiochemical procedure which involves separation of the element of interest by use of an ion-exchange resin and subsequent beta counting.
l All gamma-spectroscopic ' analyses were perfomed with a Ge(Li) detector.
~
Levels of iodine-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.
Tritium levels were determined by liquid scintillation technique.
l Analytical procedures used by the Nuclear Sciences Department of Hazleton Environmental Sciences are specified in detail elsewhere (Hazleton Environ-l mental Sciences,1981).
Procedures are based on those prescribed by the National Center for Radiological Health of the U. S. Public Health 2
Service (U. S. Public Health Service,1967) and by the Health and Safety Laboratory of the U. S. Atomic Energy Commission (U. S. Atomic Energy Commi ssion,1972).
Hazleton Environmental Sciences has a comprehensive quality control /
I quality assurance program designed to assure the reliability of data obtained.
Details of Hazleton's QA Program are presented elsewhere (Hazleton Environmental Sciences 1982).
The HES QA Program includes participation in laboratory intercomparison (crosscheck) programs.
Results obtained in crosscheck programs are presented in Appendix A.
3.5 Program Modifications There were no program modifications in 1982.
3.6 Census of Milch Animals In accordance with Technical Specification 4.10, paragraph B, several surveys of milch animals were conducted in the area of the Plant during 1982.
On June 2, 1982 an extensive survey was conducted with a one mile radius of the Plant (or 15 mR/ year distance).
Cattle observed were used for beef rather than milk production.
No new milk producing herds were found.
HAZLETON ENVIRONMENTAL SCIENCES On June 3 and 4,1982 a census for milk cows within a five mile radius was compl eted.
With the assistance of the Agricultural Agent of Goodhue and Pierce Counties, it was determined that there were no changes in the milk herds in Minnesota and only location changes on the map of milk herds in Wi sconsin.
'I-Current raw milk sampling locations were not affected. No new herds were identified.
I l
On June 3 and 4,1982 a census of goat herds within a 15 mile radius of the Plant was completed.
After visits with three county agricultural agents, it was determined that there were no reliable suppliers of goat milk in the area.
Milk from several goats in the area was used by the families.
However, milk production was sporadic.
Although goat milk
~
sampling is not a part of the routine program, certain goat milk samples, 4
when available, were collected and analyzed.
l On September 7,1982, the mid-season census of milch producing animals was completed. No new herds were identified. Mr. Albert Dosdahl (2.5 miles NE of station), went out of the dairy business. Another dairy herd close to the Dosdahl Farm, the R Johnson Farm (2.6 miles ENE' of station) was chosen as a replacement. The change took place in October 1982.
(The NRC was informed by letter dated October 26, 1982.)
4.0 RESULTS AND DISCUSSION 3,
All collections and analyses were made as scheduled (see Table 5.3).
l All results are summarized in Table 5.4 in a fonnat 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.
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.
7
HAZLETON ENVIRONMENTAL SCIENCES 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 - test effects were airborne particulates.
To a limited extent, some residual effect of previous nuclear tests was detected in milk, river water, bottom sediments, and soil (radiostrontium and cesium y
-137).
Ambient Radiation (TLDs)
At four regular air sampling locations, indicator TLDs averaged 12.1 mR/91 days and control TLDs averaged 15.2 mR/91 days.
The doses measured by control TLDs were about 25% higher than indicator TLDs.
Higher readings at control locations are due to higher readings at location P-2, which historically yielded about 30% higher readings than the second control
- location, P-1.
The means at special locations were similar to those measured at regular air sampling locations and ranged from 12.0 mR/91 days at inner ring locations to 13.0 mR/91 days at outer ring locations. The 3-differences are not statistically significant.
The dose rates measured were similar to those observed in 1978 (12.1 and 15.1 mR/91 days, respec-tively; in 1979 (12.6 and 15.3 mR/91 days, respectively), in 1980 (11.2 and 13.5 mR/91 days, respectively), and in 1981 (13.0 and 14.5 mR/91 days, respectively).
No Plant effect on ambient gamma radiation was indicated.
Air Particulates The average annual gross beta activity in airborne particulates was sim-3 ilar at 'both indicator and control locations (0.024 pC1/m ) and control 3
locations (0.026 pCi/m ) and was about four times lower than in 1981 (0.111 pC1/m3). The decrease in activity is attributable to the cleansing of the atmosphere of radioactive debris produced by the nuclear test con-ducted on 16 October 1980.
The highest averages for gross beta were for the month of January and February and the first quarter, then gradually decreased 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 October 16, 1980.
The spring peak, which usually is observed in April - May (2nd quarter) was somewhat l
obscured by the elevated activity during the first quarter. This peak has been observed almost annua 11y' (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).
I
~
Two pieces of evidence indicate conclusively that the elevated activity observed during the first quarter was not attributable to the Plant.
In 8
l
HAZL.ETON ENVIRONMENTAL. SCIENCES the first place, elevated activity of similar size occurred simultaneously at both the indicator and control locations.
Secondly, an identical pattern was observed at the Monticello Nuclear Generating Plant, about 100 miles distant from the Prairie Island Nuclear Generating Plant (Northern States Power Company, 1983).
Except for beryllium-7, which is produc'ed contiinuously in the upper atmosphere by cosmic radiation (Arnold and Al-Salih, 1955), all other gamma-emitting isotopes were below their respective LLD levels.
None of the activities detected were attributable to the Plant operation.
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 on 0.25 pCi/l in all samples.
Strontium-90 results were nearly identical at both indicator and control locations (2.6 and 3.3 pCi/1, respectively) and were in the range of 1.6 4
to 5.0 pCi/1, a range consistent with 1976, 1977, 1978, 1979, 1980 and 1981 observations at Prairie Island.
Strontium-90 levels in this range are attributable to worldwide fallout from previous atmospheric nuclear tests and reflect the long half-life (28.6 years) 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 quantities.
Finally, all strontium-89 results in 1982 were >2.6 pCi/1, in agreement with 1976, 1977, 1978, 1979, 1980, and 1981 measurements.
No significant changes were seen in strontium-90 levels in milk.
Levels were similar to those observed in 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 isotopes, except potassium-40, were detected in any of the 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 l
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 sumary, the milk data for 1982 show no radiological effects of the Plant operation, but the presence of strontium-90 in milk samples does exhibit a long range residual effect of previous atmospheric nuclear tests.

MA78 WTON ENVIRONMENTAI. SCIENCES Drinking Water In drinking water from the City of Red Wing well, tritium activity was below the LLD level of 330 pC1/1 in all samples.
As with the other well water samples, all analyses for gamma-emitting isotopes yielded results below detection ifmits.
Gross beta averaged 8.9 pCi/1 and was similar to a
i the levels observed in 1979 (10.5 pCi/1), 1980 (11.8 pCi/1, and 1981 (10.7 pC1/1 ).
i River Water At the upstream and downstream collection sites, quarterly composite tritium levels were below the LLD level of 330 pC1/1 in all sampl es.
River water was.also analyzed for gamma-emitting isotopes, strontium-89, and strontium-90. All gamma-emitting isotopes and strontium-89 were below their respective detection limits.
Strontium-90 was detected in all upstream and downstream samples.
The mean activity was nearly identical in both the upstream samples (1.1 pCi/1) and the downstream samples (1.3 pCi/1). There was no indication of a Plant effect.
Well Water At the control well P-25, Kinneman Fam and two indicator wells (P-8, Kinney Store, and P-10, Lock and Dam #3) no tritium was detected above LLD level of 330 pC1/1 in any of the analyses.
At the remaining indicator well (P-9, Plant Well #2), tritium was detected in three quarterly samples and ranged from <380 to 590 pCi/1, averaging 460 pCi/1.
Gamma-emitting isotope levels were below detection limits in all cases.
Crops Cabbage amples were collected on August 23, 1982, and analyzed for fodine-131.
Corn samples were also collected on August 23, 1982, and analyzed for gamma-emitting isotopes.
All results, except for potassium j
-40, were below detection limits.
There was no indication of a Plant effect.
Natural Vegetation I
Natural vegetation was collected on May 10 and August 23, 1982.
No iodine-131 was observed in any of the samples collected.
All other gamma-emi tting isotopes, except for bery111um-7, which is constantly produced in the upper atmosphere by cosnic rays, and naturally-occuring potassium-40 were below their respective LLD's.
Thus, no Plant effect is indicated.
10
HA78 BTON ENVIRONMENTAL SCIENCES Topsoil Soil is collected every three years and was collected in 1979 prior to the August 23, 1982 collection.
Strontium-90 was detected in all soil samples, and averaged 0.187 and 0.261 pCi/g dry weight in indicator and control samples, respectively.
Cesium-137 was also detected in all samples and averaged 0.61 and 0.83 pCi/g dry weight in indicator and control samples, respectively.
The other gamma-emitting isotope detected was potassium-40. No Plant effect is indicated.
Fish Fish samples were collected in May and September,1982. The only isotope detected was naturally-occuring potassium-40 and there was no significant difference between upstream and downstream results.
There was no indica-tion of a Plant effect.
Aquatic Insects and Periphyton Aquatic insects (macroinvertebrates) and periphyton were collected on June 15 and October 13, 1982. The samples were analyzed for strontium-89, strontium-90 and gamma-emitting isotopes.
Strontium-89 was below the limits of detection in all samples.
Mean strontium-90 levels were very low and averaged 0.043 pCi/g wet weight in the upstream (control) sample and 0.072 pCi/g wet weight in the downstream sample.
The difference between the downstream and upstream samples was not statistically signif-icant since uncertainty in the measurement is about at the same magnitude as the difference.
All other gamma-emitting isotopes, except for nat-urally-occuring potassium-40, were below their respective LLD's. No Plant effect was indicated.
Aquatic Yegetation 1
i Aquatic vegetation was collected on June 25 and August 31, 1982 and analyzed for gamma-emitting isotopes.
All results, except for potassium
-40, were below detection limits. No Plant effect was indicated.
Bottom and Shoreline Sediments Sediment. collections were made on May 24 and August 31, 1982.
The i
samples were analyzed for strontium-90 and gamma-emitting isotopes.
Strontium-90 was below the LLD of 0.014 pC1/g dry weight in all but two
[
sampl es.
Cerium-137 was detected in three bottom sediment samples and averaged 0.096 pCi/g dry weight in indicator samples and was 0.153 pCi/g dry weight in one upstream (control) sample.

HAZf.ETON ENVIRONMENTAL. SCIENCES Appendix A Crosscheck Program Results e
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 b agencies which supply environmental-type samples (e.g.,
milk water) ycontaining concentrations of radionuclides known to the issuing or agency but not to participant laboratories.
The purpose of such a program is to provide an independent check on the laboratory'( analytical procedures and to alert it to any possible problems.
i 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 values or outside the control limits indicate a need to check the instruments or procedures j
used.
The results in Table A-1 were obtained through participation in the environ-mental sample crosscheck program for n; ilk and water samples during 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 dosimeters (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.

Computation of Avuages and Standard Deviations t
4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; e
for example, an annual standard deviation would_not be the average i
of quarterly standa'rd deviations. The average x and standard
~
are defined deviations of a set of n numbers x1> X2,... xn i
as follows:
x = f Ix II*~*I2
~
j 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 grcup are less than the l
highest LLD, the highest LLD is reported.
4.4 If all but one of the values are less than the highest LLD, the l
single value x and associated two sigma error is reported.
I~
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, I
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 i
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.
