1.0 INTRODUCTION
This report summarizes and interprets results of the Radiological Environmental Monitoring Program conducted by Teledyne Brown Engineering Environmental Services, Midwest Laboratory at the Duane Arnold Energy Center, Palo, Iowa, during the period January -
December,1998. This Program monitors the levels of radioactivity 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 water reactor. Initial criticalik was attained on 23 March 1974. The reactor reached 100%
power on 12 August 1974. Ccf knercial operation began on 1 February 1975.

SUMMARY
The Radiologicil Environmental Monitoring Program required by the U.S. Nuclear Regulatory Commission (NRC) Technical Specifications for the Duane Arnold Energy Center is described.
Results for 1998 are summarized and discussed.
Program findings show background levels of radioactivity in the environmental samples collected in the vicinity of the Duane Arnold Energy Center. With the exception of D-107, located within the owner controlled area, no effect on the environment due to the operation of the Duane Arnold Energy Center is indicated.

r 3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 3.1 Procram Desien and Data Interpretation The purpose of the Radiological Environmental 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 j
radionuclides; (2)
Fallout from atmospheric nuclear detonations; (3)
Releases from nuclear power plants; and (4)
Industrial and medical radioactive waste.
i 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 control locations (distant, upwind, or upstream). A station effect would be indicated if the radiation level at an mdicator 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 technic ue 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 fis tion 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 i
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 t ne 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-i 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.

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.
Characteristic properties of isotopes quantified in gamma-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, airbome particulates are collected on membrane filters by continuous pumping at twelve locations. Also, airborne iodine is collected by continuous pumping through charcoal filters at six of these locations. Nine of the twelve locations are indicators and three 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 detector.
Charcoal filters are analyzed weekly for I-131 on all samples.
Ambient gamma radiation is monitored at twelve sir sampling locations. In addition, gamma radiation is monitored at thirty-three special locations: seventeen in a circle within 0.5 mi. radius of the DAEC stack; six in 22.5* sectors within 1 mi. of the DAEC stack; and ten in 22.5 sectors between I 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 five 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 mor.itoring of the terrestrial environment, grain, hay and broad leaf vegetation samples are collected annually, as available, from nine locations: one control (D-105) and eight edicators (D-16, D-57, D-58, D-63, D-72, D-93, D-94, and D-106).
Grain, hay and broad leaf (green leafy) vegetation samples are analyzed for gamma-4
Program Description (continued) j 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 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 river, pond and sewage effluent locations, one control (D-49) and four 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 i
(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). Tha 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)
TLD data was not available for the first and second quarters,1998 from location D-48. The TLDs were lost in the field.
(2)
TLD data was not available for the fourth quarter,1998 from locations D-18 and D-43. The TLDs were lost in the field.
(3)
No milk was available from location D-93 for the months of December and January,1998. No milk was available from location D-101 for January through April and December,1998. The goats were dry.
(4)
One cooler containing milk from location D-105, collected June 18,1998,and surface water from location D-49, collected June 15,1998 was lost in shipment.
(5)
Air particulate / Air iodine samples for all locations were missed for the week i
ending December 3,1998. The samples were collected and shipped according to l
specifications, but were misplaced by the laboratory.

t
i 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 ofioc 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 TBEESML are on file and are available for inspection.
Procedures are based on those prescribed by the Health and Safety Laboratory of the U.S. Dep't of Energy, Edition 28,1997, U.S. Environmental Protection Agency for Measurement of Radioactivity in Drinking Water,1980, and the U.S. Environmental Protection Agency, EERF, Radiochemical Procedures Manual,1964.

7 4.0 RESULTS AND DISCUSSION All of the scheduled collections and analyses were made on schedule except those listed in Table 5.6.
All results are summarized in Table 5.7 in a format recommended by the Nuclear Regulatory Commission in Regulatory Guide 4.8. For each type of analysis of each sample medium, this table lists the mean and range of all indicator and control locations. The locations with the highest mean and range are also shown.
The tabulated results of all measurements made in 1998 are not included in this section, although references to these results will be made in the discussion. The complete tabulation of the 1998 results is contained in Part II of the 1998 Annual Report on the Radiological Environmental Monitoring Program for the Duane Arnold Energy Center.

There were no reported accidents at nuclear reactor facilities in 1998.
4.2 Procram Findines Results obtained show background levels of radioactivity in the environmental samples collected in 1998.
Airborne Particulates The average annual gross beta concentrations in airborne particulates were identical at j
3 both indicator and control locations (0.024 pCi/m ) and were similar to levels observed i
from 1984 through 1997. The :esults are tabulated below. The data for 1986 does not include the results from May 19 to June 9,1986, which were influenced by the accident at Chernobyl.

Gamma spectroscopic analysis of quarterly composites of air particulate filters yielded similar results for indicator and control locations. Beryllium-7, which is produced 7
L.
Airborne Particulates (continued) continuously in the upper atmosphere by 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.
AirbomeIodine Weekly levels of airborne iodine-131 were below the lower limit of detection (LLD) of 0.07 pCi/m3 n all sampas.
i Ambient Radiation (TLDs)
At twelve air sampling locations, the TLD readings averaged 14.7 and 14.4 mR/ quarter for indicator and control locations, respectively. At locations within 0.5 mile,1.0 mile, and 3.0 mile radius of the stack, the measurements averaged 16.9 mR/ quarter,18.6 mR/ quarter, and 15.2 mR/ quarter, respectively. The average for all locations was 16.1 mR/ quarter. This is 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.
Milk Iodine-131 results were below the detection limit of 1.0 pCi/L in all samples.
No gamma-emitting isotopes, except naturally 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 of potassium, cesium, strontium, barium, and iodine (National Center for Radiological Health,1968).
In summary, the milk data for 1998 show no radiological effects of the plant operation.
Ground Water The annual mean for gross beta activity measured 2.9 pCi/L and was similar to the levels observed in 1980 through 1997. The location with the highest mean (5.2 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.

Vegetation Iodine-131 results in broadleaf vegetation were below the LLD level of 0.040 pCi/g wet 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.
Snil Strontium-90 was detected in both samples and averaged 0.03' pCi/g dry w'eight.
Cesium-137 was detected at an average concentration of 0.15 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), in 1993 (0.058 and 0.26 pCi/g dry weight, respectively), in 1994 (0.040 and 0.27 pCi/g dry weight, respectively), in 1995 (0.044 and 0.21 pCi/g dry weight, respective:y), in 1996 (0.050 and 0.17 pCi/g dry weight, respectively) and in 1997 (0.051 and 0.20 pCi/g dry weight, respectively).
The only other gamma-emitting isotope detected was potassium-40 at an average concentration of 12.53 pCi/g dry weight. No plant effect on soil was indicated.
Surface Water Tritium was below the LLD level of 330 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 12,1-26.8 pCi/L and averaged 16.2 pCi/L.
No plant effect on the radioactivity of surface water was indicated.
Fish All gamma-emitting isotopes, except naturally-occurring otassium-40, in edible portions were below detection limits. The potassium 40 level was similar at both indicator and control locations (3.37 and 3.29 pCi/g wet weight, respectively). No plant effect on fish was indicated.
River Sediments River sediments were collected in May and September,1998, and analyzed for gamma-emitting isotopes. Cobalt-60 was detected in one sample from location D-107 (sewage effluent) at a concentration of 0.084 pCi/g dry weight. Cesium-137 was detected at two locations, D-107 (sewage effluent) at a concentration of 0.051 pCi/g dry weight, and D-51 (discharge) at a concentration of 0.034 pCi/g dry weight. Potassium-40 ranged from 7.38-9.26 pCi/g dry weight and averaged 8.68 pCi/g dry weight.
All other gamma-emitting isotopes were below detection limits.

NOTE: Teledyne's Midwest Laboratory participates in intercomparison studies administered by U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. The results are reported in
. Appendix A. Also reported are results of Intemational Intercomparison and Teledyne testing of TLD's, as well as, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results. Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.
January,1998-through December,1998
Appendix A Interlaboratory Cornparison Procrarn Results Taledyne Brown Engineering Environmental Services 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 analytical procedures and to alert it to any possible 1
problems.
Pirticipant 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.
j The results in Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water and air filters during the past twelve months. Data for previous years is cvailable upon request.
This program is conducted by the U.S. Environmental Protection Agency Office of Research and Developement National Exposure Research Laboratory Characterization Research Division-Las Vegas, Nevada.
The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various laternationalIntercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2.
Also Teledyne testing results are listed.
Ttble A-3 lists results of the analyses on in-house " spiked" samples for the past twelve montlts. All samples are prepared using NIST traceable sources. Data for previous years availab)e upon request.
Tcble A-4 lists results of the analyses on in-house " blank" samples for the past twelve months. Data for previous years available upon request.
Table A-5 list results of the in-house " duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.
The results in Table A-6 were obtained through participation in the mixed analyte performance cvaluation program.
The results in Table A-7 were obtained through participation in the Environmental Measurement Laboratory Quality Assessment Program.
Attachment A lists acceptance criteria for " spiked" samples.
Out-of-limit results are explained directly below the result.

2.0. hgle Measurements Each single measurement is reported as follows:
xis where x = value of the measurement; s = 2a counting uncertainty (corresponding to the 95% confidence level).
In cases where the activity is found to be below the lower limit of detection L it is reported as
<L where L = the lower limit of detection based on 4.66o uncertainty for a background sample.

4.0. Computation of Averages and Standard Deviations 4.1 Averages 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 standard deviations. The average i and standard deviation s of a set of n numbers xi,x2 x are defined as follows:
n x=fEx I(x-x)2 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 LLD is reported.
4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma erroris 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 equal to or greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example,11.445 is rounded off to 11.05.

SUMMARY
OF THE LAND USE CENSUS 4
D-1
l Appendix D Summary of the Land Use Census l
l The Duane Arnold Energy Land Use Census for 1998 was completed during the fourth j
week of September 1998. All milk animals and gardens greater than 500 square feet were q
identified within three miles for each of the 16 meteorological sectors. If none were l
identified within the three mile range, additional surveys were performed out to a distance l
of five miles. The Cedar River was surveyed by boat on July 24th 1998 for water use l
downstream of the DAEC to Cedar Rapids.
There were 154 gardens found during the performance of the 1998 Census. This number exceeds the number of gardens found in the 1997 survey by 7. This difference can be attributed to the removal of 21 gardens and the addition of 28 new gardens.
Milk animallocations remained unchanged since the 1995 census. Two of the locations have goats that do not provide samples during the winter months.
]
The locations of the nearest resident for each sector remained the same. Twenty-one new homes were built or were under construction within three miles of the DAEC, compared to the 22 new homes identified in 1997. Most of the new houses built were located in the sectors between the plant and Cedar Rapids (ESE and SE).
l The Cedar River survey revealed no new withdrawals of river water compared to previous surveys. Irrigation of the strawberry farm in Palo and fishing remain the only food pathway uses of river water between the DAEC and Cedar Rapids.
l As a result of this census, no adjustments were made to the MIDAS dose projection

software model.

)
Appendix E 4
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 j
releases.
Section A.
Dose Contribution from Direct Radiation Direct radiation dose from the operation of the DAEC was reported by TLDs placed at locations in the surrounding environment as described in the Offsite Dose Assessment Manual (ODAM).
- 1. Pre-operational and 1998 TLD results were compared using a paired difference test.
No significant differences in the TLD populations were observed for the 0.5 mile and one mile TLD populations using a confidence level of 99%.
j 4
- 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 Efnuent 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 System (MIDAS) computer program in accordance with 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 were due to the operation of the 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 are shown in tabular form on page E-4
- 1. There were no releases of radioactive material to liquid effluents in 1998.
- 2. The dose to air from noble gases released was 1.48E-03 mrad from gamma radiation at 535 meters SSW and 2.27E-02 mrad beta radiation at 535 meters SSW.
- 3. The total body dose equivalent to the maximally exposed individual from noble gases was 1.81E-03 mrem, at 805 meters West.
E-2
- 4. The skin dose equivalent to the maximally exposed individual from noble gases was 1.84E-03 mrem, at 805 meters West.
- 5. The maximally exposed organ due to iodines and particulates with half-lives greater than eight days was the thyroid of a child at 805 meters West, with and estimated dose equivalent of 8.01E-03 mrem.
==
Conclusion:==
No measurable dose due to the operation of the DAEC was detected by environmental TLDs in 1998. The calculated doses are below the regulatory limits stated in Appendix 1 to 10 CFR 50 and in 40 CFR 190.
