1.0 INTRODUCTION
t This report summarizes and interprets results of the Environmental Radiological Monitoring Program conducted by Teledyne Isotopes Midwest Laboratory at the Duane Arnold Energy ;
Center, Palo, Iowa, during the period January - December 1994. This Program monitors the levels of radioactivit; in the air, terrestrial, and aquatic environments in order to assess the impact of the Plant on its surroundings.
Tabulation of the individual analyses made during the year are included in Part II of this report. !
Duane Arnold Energy Center (DAEC) is located in Linn County on the Cedar River, Iowa, and :
is operated by IES Utilities, Inc. The Duane Arnold Energy Center is a 565.7 MW(e) boiling l water reactor. Initial criticality was attained on 23 March 1974. The reactor reached 100% !
power on 12 August 1974. Commercial operation began on 1 February 1975. ;

l 3.0 ENVIRONMENTAL RADIOLOGICAL MONITORING PROGRAli 3.1 Procram Desien and Data Interoretation i
The purpose of the Environmental Radiological Monitoring Program at the Duane Arnold Energy Center (DAEC) 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 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; and (4) Industrial and medical radioactive waste.
In interpreting the data, effects due to the DAEC operation 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 DAEC which is based on the indicator-control concept. Most types of samples are collected both at indicator locations (nearby, downwind, or downstream) and at contrc,1 locations (distant, upwind, or upstream). A station effect would be indicated if the radiation level at an indicator location was significantly 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 environmental samples collected from the DAEC site. The DAEC's monitoring program includes analyses for strontium-90 and iodine-131, which are fission products, and tritium, which is produced by cosmic rays, atmospheric nuclear detonations, and also by nuclear power plants. Most samples are also analyzed for gamma-emitting isotopes with results for the following groups quantified: zirconium-95, cesium-137, and cerium-144. These 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 produced in roughly equivalent amounts by a reactor: each constitutes about 10% of the total activity of fission products ten (10) days after reactor shutdown. On the other hand, ten (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). The other group quantified consists of niobium-95, ruthenium-103 and -106, cesium-134, barium-lanthanum-140, and cerium-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 atmospheric nuclear testing. Nuclides of the next 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 effluents, but are not produced in significant quantities by nuclear detonations.

L 3.1 Program Design and Data Interoretation (continued)
Nuclides of the final group, beryllium-7, which is of cosmogenic origin, and potassium-40, a naturally-occurring isotope, were chosen as calibration monitors and should not be ,
considered radiological impact indicators. t Characteristic properties of isotopes quantified in garmna-spectroscopic analysis are presented in Table 5.1. Other means of distinguishing sources of environmental radiation can be employed in interpreting the data. Current radiation levels can be compared with previous levels, including those measured before the Plant became operational. Results of the DAEC'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 environmental radiological monitoring program at the DAEC is summarized in Table 5.2 and is briefly reviewed below. Table 5.3 defines the sampling location codes used in Table 5.2 and specifies for each location its type (indicator or control) and its distance, direction, and sector relative to the reactor site. The types of samples collected at each location and the frequency of collections are presented in Table 5.4 using codes defined in Table 5.5.
To monitor the air environment, airborne particulates are collected on membrane filters by continuous pumping at twelve (12) locations. Also, airborne iodine is collected by continuous pumping through charcoal filters at six (6) of these locations. Nine (9) of the twelve (12) locations are indicators and three (3) are controls (D-1, D-2, and D-13).
Filters are changed and counted weekly. Particulate filters are analyzed for gross beta activity. If gross beta activity exceeds 10 times the yearly mean of the control samples '
gamma isotopic analysis is performed. Quarterly composites of airborne particulates from each location are gamma scanned on a germanium c.etector.
Charcoal filters are analyzed weekly for I-131 on all samples.
Ambient gamma radiation is monitored at twelve (12) air sampling locations. In addition, gamma radiation is monitored at thirty-two (32) special locations: seventeen (17) in a circle within 0.5 mi. radius of the DAEC stack; six (6) in 22.5* sectors within 1 mi. of the DAEC stack; and nine (9) in 22.5 sectors between 1 and 3 miles of the DAEC stack. Two TLDs are placed at each location and are exchanged and analyzed quarterly.
Precipitation samples are collected monthly from one location and analyzed for gamma-emitting isotopes. Quarterly composites are analyzed for tritium.
Milk samples are collected monthly from six (6) locations during the non-grazing season, October through April, and biweekly during the grazing season, May 1 through September 30. One location is a control (D-105) and the rest are indicators. All samples are analyzed for I-131 and gamma-emitting isotopes.
For additional monitoring of the terrestrial environment, grain, hay, and broad leaf vegetation sampics are collected annually as available from nine (9) locations: one control (D-105) and eight (8) indicators (D-57, D-58, D-63, D-72, D-93, D-94, D-106 4
Program Description (continued) and D-16). Grain, hay, and broad leaf (green leafy) vegetation samples are analyzed for gamma-emitting isotopes and at least one broad leaf vegetation is analyzed for iodine-131. If cattle are slaughtered for home use, a meat sample is collected annually, during or immediately following a grazing period from animals grazing on-site. The sample is analyzed for gamma-emitting isotopes. Also, potable ground water is collected quarterly from a treated municipal water system (D-53), the inlet to the municipal water treatment system (D-54), and four (4) additional ground water locations (D-55, D-57, D-58, and D-72). The samples are analyzed for gross beta and tritium. If gross beta activity exceeds 10 times the yearly mean of the control samples, gamma isotopic, strontium-89, and strontium-90 analyses are performed.
Soil samples are collected once per year at two indicator locations (D-15 and D-16).
The samples are analyzed for strontium-90 and gamma-emitting isotopes. -
Surface water is collected monthly from five (5) river, pond, and sewage effluent locations, one (1) control (D-49) and four (4) indicator (D-50, D-51, D-99, and D-107). .
All monthly samples are analyzed for gamma-emitting isotopes. Tritium analyses are performed on quarterly composites from each location. In addition, all samples from Location D-107 (plant sewage discharge) are analyzed for K-40 by flame photometry.
The aquatic environment is also monitored by upstream and downstream (D-49 and D-
- 61) semiannual collections of fish. River bottom sediment is also collected semiannually at the plant's intake and discharge (D-50 and D-51) and downstream of the sewage plant (D-107). The samples are analyzed for gamma-emitting isotopes.
3.3 Program Execution The program was executed as described in the preceding section with the following exceptions:
(1) Milk was not available from location D-93 for the month of January and December,1994.
(2) Milk was not available from location D-101 for the months of January, February, March and April,1994.
(3) TLDs were missing at location D-11 for all four quarters of 1994 due to vandalism.
(4) TLDs were missing from location D-10 for the second quarter of 1994. !
i (5) TLDs were missing from location D-40 for the third quarter of 1994.
(6) TLDs were missing from location D-37 for the fourth quarter of 1994.

3.4 - Laboratorv Procedures ;
All iodine-131 analyses in milk were made by using a sensitive radiochemical procedure which involves separation of the element by use of an ion-exchange resin and subsequent beta counting.
All gamma-spectrosco sic analyses were performed with high resolution germanium detectors. Levels of ioc ine-131 in vegetation were determined by gamma spectrometry. ;
Levels of airborne iodine-131 in charcoal samples were measured by gamma spectrometry.
Tritium levels were determined by the liquid scintillation technique.
Analytical Procedures used by TIML are specified in detail elsewhere (Teledyne Isotopes Midwest Laboratory,1994). Procedures are based on those prescribed by the National Center for Radiological Health of the U.S. Public Health 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 Commission,1972). ;
Details of TIML's QA program are presented elsewhere (Teledyne Isotopes Midwest Laboratory,1994 ). The TIML QA Program includes participation in the Interlaboratory ;
Comparison (Crosscheck) Program. Results obtained in the crosscheck program are !
presented in Appendix A.
3.5 Program Modifications A new milk animal sampling location (D-72) was added to the program in January, 1994.

4.1 Atmospheric Nuclear Detonations and Nuclear Accidents l
There were no reported atmospheric nuclear tests in 1994. The last reported test was conducted by the People's Republic of China on October 16,1980. The reported yield was in the 200 kiloton to 1 megaton range.
There were no reported accidents at nuclear reactor facilities in 1994.
4.2 Procram Findines Results obtained show background levels of radioactivity in the environmental samples collected in 1994.
Airborne Particulates The average annual gross beta concentration in airborne particulates was similar at indicator and control locations (0.023 and 0.024 pCi/m3, respectively) and was similar to levels in 1984 (0.025 and 0.026 Ci/m3, respectively), 1985 (0.024 pCi/m3 at both locations), in 1986 (0.024 pCi/m , at both indicator and control locations), in 1987 (0.024 and 0.026 pCi/m 3, respectively), in 1988 (0.026 and 0.028 pCi/m3, respectively), in 1989 (0.026 and 0.029 pCi/m 3, respectively), in 1990 (0.022 and 0.024 pCi/m ,3respectively), in 1991 (0.023 and 0.022 pCi/m 3, respectively), in 1992 (0.022 and 0.023 pCi/m3, respectively) and in 1993 (0.022 and 0.023 pCi/m3, respectively) .
The average of 0.024 pCi/m3for 1986 does not include the results from May 15 to June 12,1986, which were influenced by the accident at Chernobyl.
A s ating peak in beta activity had been observed almost annually for many years (Wi son d al.,1969). It had been attributed to fallout of nuclides from the stratosphere (Gold d al.,1964). It was pronounced in 1981, occurred to a lesser degree in 1982, and did not occur in 1983,1984,1985,1987,1988,1989,1990,1991,1992,1993 or 1994. In 1986, the spring peak could not be identified because it was overshadowed by the releases of radioactivity from Chernobyl. Gamma spectroscopic analysis of quarterly composites of air particulate filters yielded similar results for indicator and control locations. Beryllium-7, which is produced continuously in the upper atmosphere by 7
Airborne Particulates (continued) cosmic radiation (Arnold and Al-Salih,1955), was detected in all samples. All other gamma-emitting isotopes were below their respective LLD limits. No plant effect was indicated.
Airbome Iodine Weekly levels of airborne iodine-131 were below the lower limit of detection (LLD) of 0.07 pCi/m3 in all but two samples. In both cases, the required LLD was exceeded due to low volumes (31 m3 and 35 m3). The I-131 concentrations measured <0.10 and
<0.11 pCi/m3 ,
Ambient Radiation (TLDs)
At eleven (11) air sampling locations, the TLD readings averaged 15.3 mR/ quarter at indicator locations and 14.8 mR/ quarter at control locatior.s. At locations within a 0.5 mile,1.0 mile, and 3.0 mile radius of the stack, the measurements averaged 17.0 mR/ quarter,18.0 mR/ quarter, and 15.8 mR/ quarter, respectively. The average for all locations was 17.7 mR/ quarter. This is slightly lower than the estimated average natural background radiation for Middle America,19.5 mR/ quarter, which is based on data on Pages 71 and 108 of the report, " Natural Background Radiation in the United States" (National Council on Radiation Protection and Measurements,1975). The terrestrial absorbed dose (uncorrected for structural and body shielding) ranges from 8.8 to 18.8 mrad / quarter and averages 11.5 mrad / quarter for Middle America. Cosmic radiation and cosmogenic radionuclides contribute 8.0 mrad / quarter for a total average of 19.5 mrad / quarter. No plant effect was indicated.
Precipitation .
In precipitation, the tritium concentration was below the LLD of 330 pCi/L in all samples. No gamma-emitting isotopes were detected. No plant effect was indicated.
hiilk Iodine-131 results were below the detection limit of 1.0 pCi/L in all samples. I No gamma-emitting isotopes, except natur ally occurring 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 radioisotopes 1 of potassium, cesium, strontium, barium, and iodine (National Center for Radiological l Health,1968). I In summary, the milk data for 1994 show no radiological effects of the plant operation.
Ground Water The annual mean for gross beta activity measured 3.8 pCi/L and was similar to the levels observed in 1980 through 1993. The location with the highest mean (8.0 pCi/L) was D-58, a farm 1.0 mile distant from the plant. Tritium was below the LLD of 330 pCi/L in all samples. No plant effect was indicated. j 8
I s
Vecetation Iodine-131 results in broad leaf vegetation were below the LLD level of 0.046 pCi/g wet 1 weight in all samples. !
Except for potassium-40, which was observed in all vegetation samples ( broadleaf, grain, and forage ), all other gamma-emitting isotopes were below detection limits in all samples. No plant effect is indicated.
Soil Strontium-90 was detected in both samples and averaged 0.040 pCi/g dry weight.
Cesium-137 was detected in both samples at an average concentration of 0.27 pCi/g dry weight. Both strontium-90 and cesium-137 concentrations were similar to levels observed in 1987 (0.08 and 0.30 pCi/g dry weight, respectively), in 1988 (0.064 and 0.33 pCi/g dry weight, respectively), in 1989 (0.046 and 0.18 pCi/g dry weight, respectively), in 1990 (0.066 and 0.21 pCi/g dry weight, respectively), in 1991 (0.064 and 0.34 pCi/g dry weight, respectively), in 1992 (0.040 and 0.26 pCi/g dry weight, respectively) and in 1993 (0.058 and 0.26 pCi/g dry weight, respectively).
The only other gamma-emitting isotope detected was potassium-40 at an average concentration of 14.1 pCi/g dry weight. No plant effect on soil was indicated.
Surface Water Tritium was below the LLD level of 30 pCi/L in all samples.
All gamma-emitting isotopes were below their respective LLDs.
K-40 was measured at one location, D-107 (sewage effluent). The concentration ranged from 13.0 to 24.9 pCi/L and averaged 16.4 pCi/L.
No plant effect on the radioactivity of surface water was indicated.
fish All gamma-emitting isotopes, except naturally-occurring potassium-40, in edible portions were below detection limits. The potassium-40 level was similar at both indicator and control locations (3.14 and 2.92 pCi/g wet weight, respectively). No plant effect on fish was indicated. !
River Sediments River sediments were collected in May and September,1994, and analyzed for gamma-l emitting isotopes. Cobalt-60 was detected in two samples from location D-107 (sewage l
effluent) at an average concentration of 0.12 pCi/g dry weight. Cesium-137 was detected at both indicator locations at an average concentration of 0.045 pCi/g dry weight. Potassium-40 ranged from 8.86 to 16.80 pCi/g dry weight and averaged 11.11 pCi/g dry weight.
All other gamma-emitting isotopes were below detection limits.

d locations are specified by: (1) Name and code (Table 5.3); and (2) distance, direction, and sector relative to reactor site.
- Non-routine results are those which exceed ten times the control station value for the location. If a control station value is not available, the result is considered non-routine if it exceeds ten times the preoperational value for the location.
I 1hree results were ehmmated from the calculations for mean and standard deviation due to low volumes.
8 One result for 1-131 at location D-2 and one result for I-131 at location D-8 exceeded the lower limit of detection requirement due to low volumes (31 m 3and 35 m ,3respectively).1he I-131 concentrations measured <0.10 and <0.11 pCi/m 3, respectively.
h One result for precipitation was eliminated from the LLD calculation due to low sample volume (100 ml.).

1 Apoendix A Interlaboratory Comoarison Procram Results l Teledyne's Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's 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 i analytical procedures and to alert it to any possible problems. i i
Participant laboratories measure the concentration 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 used.
i The results in Table A-1 were obtaine:I through participation in the environmental sample crosscheck l program for milk, water and air filters during the past twelve months, Data for previous years is available upon request. .
This program is conducted by the U.S. Environmental Protection Agency Intercomparison and i Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, !
Las Vegas, Nevada.
{
l The results in Table A-2 were obtained for '!hermoluminescent Dosimeters (TLDs), since 1976 via various International Intercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2. Also Teledyne testing results are listed.
Table A-3 lists results of the analyses on in-house " spiked" samples for the past twelve months.

It states, "The Radiation Quality Assurance Program has been experiencing problems with the Ruthenium-106 currently used in the Performance Evaluation (PE)
Studies and in the Standards Distribution Program. If these problems can be satisfactorily resolved, this analyte will once again be placed into this PE Study. If the problems cannot be resolved, the Ruthenium-106 will be replaced. Formal written notice will be given to all participants in the Gamma in Water PE Study before the Ruthenium-106 is reintroduced or replaced. At that time, new calibration standards will be available to all participants in the Gamma in Water PE Study." Teledyne will continue to monitor this situation, but at this time, plans to take no additional action.

SUMMARY
OF 1994 LAND USE CENSUS The annual Land Use Census for DAEC was completed in September 1994. All milk animals and gardens greater than 500 square feet were identified within three miles for each of the 16 meteorological sectors. Within five miles, the nearest resident, milk animal and garden in each sector were identified. !
Additionally, the Cedar River was inspected for water use ,
downstream of DAEC to Cedar Rapids. .'
f There were no new uses of water.
A total of 20 new homes were built or under construction within 3 miles of DAEC since the last census. Most of the new homes were built in the sectors toward Cedar Rapids (SSE, SE and ESE) where ;
increased building rates have been noted in previous land use l census. Eight new homes were noted in the town of Palo (S and l SSW) and four were noted near Pleasant Creek (WNW). ,
I Although the population continues to grow around the SE sector near 3 miles from DAEC, no new source pathway or source to receptor relationships have been created. No changes in the DAEC Radiological Environmental Monitoring Program are recommended based on the Land Use Census.

ANNUAL RADIATION DOSE ASSESSMENT The annual offsite radiation dose to a member of the public was determined by assessment of environmental dosimeter results and by calculations based on monitored effluent releases.
SECTION A. DOSE CONTRIBUTION FROM DIRECT RADIATION Direct radiation dose from the operation of DAEC was recorded by TLDs placed at locations in the surrounding environment as described in the Offsite Dose Assessment Manual (ODAM).
- 1. Pre-operational and 1994 TLD results were compared using a paired difference test. No difference in the TLD populations were observed for the 0.5 mile, 1 mile and 3 mile TLD populations using a confidence level of 99%.
- 2. As stated in Part 1, page 8 of this report, no plant effect was indicated by the TLDs when dose results were compared to the estimated average natural background for Middle America.
SECTION B. ESTIMATED OFFSITE DOSE FROM EFFLUENT RELEASES The contribution of dose to a member of the public most likely to be exposed from effluent releases was calculated by the Meteorological Information and Dose Assessment Systems (MIDAS) computer program in accordance with the ODAM. The calculation methods follow those prescribed by Reg Guide 1.109. Because there were no nuclides detected in the environment at or beyond the site boundary that was due to the operation of DAEC, no comparison of calculated dose from stack releases and dose calculated from environmental contamination was performed.
Results of the MIDAS dose calculations are discussed below and shown in tabular form on Page E-4:
- 1. There were no releases of radioactive material to liquid ,
effluents in 1994.
- 2. The dose to air from noble gases released was 1.19E-3 mrad from gamma radiation at the SSE site boundary and 1.96E-4 mrad from beta radiation at the North site boundary.
- 3. The total body dose equivalent to the maximally exposed individual fro: aoble gases was 5.61E-4 mrem, at 805 meters !
West.
- 4. The skin dose equivalent to the maximally exposed individual ,
from noble gases was 6.38E-4 mrem, at 805 meters West. '
E-2
- 5. The maximally exposed organ due to iodines and particulates with half-lives greater than eight days was the skin of a child at 805 meters West, with an estimated dose equivalent of 5.75E-3 mrem.
CONCLUSION:
No measurable dose due to operation of DAEC was detected by environmental TLDs in 1994. The calculated doses are below the regulatory limits stated in Appendix I to 10 CFR 50 and in 40 CFR 190.
