1 > 1 ! EEfEE i i J The U. S. Nuclear Regulatory Commission (NRC) Direct Radiation Monitoring Network is j operated by the NRC in cooperation with participating states to provide continuous measurement of the ambient radiation levels around liccased NRC facilities, primarily power reactors. Ambient i i radiat on levels result from naturally occurring radionuclides present in the soil, cosmic radiation constantly bombarding the earth from outer space, and the contribution, if any, from t:m monitored facilities and other man-made sources. 'Ihe Network is intended to measure radiation ! levels during routine facility operations and to establish background radiation levels used to assess ! the radiological impact of an unusual condition, such as an accident. 'Ihis report presents the radiation levels measured around all facilities in the Network for the third quarter of 1996. A complete listing of the site facilities monitored is included. In some instances, two power reactor i facilities are monitored by the same set of dosimeters (e.g., Kewaunee and Point Beach). j All radiation measurements are made using small, passive detectors called thermoluminescent ! dosimeters (TLDs), which provide a quantitative measurement of the radiarian levels in the area j in widch they are placed. Each site is monitored by arranging approximately 40 to 50 TLD i stations in two concentric rings extending to about five miles from the facility. All TLD stations ! are outside the site boundary of the facility. A complete description of the program can be found i in NUREG-0837, Volume 2, Number 4. A similar description can also be found in the fourth quarter report of each subsequent year. The National Institute of Standards and Technology
- (formerly the National Bureau of Standards) has performed an iet study of the following
! characteristics of the NRC dosimetry system; energy response, angular W, temperature ! and humidity sensitivity, fading, light W, self-irradiation, and reproducibility. NIST has ) also tested the response of the NRC's dosimetry system against the requirements of ANSI N545-j 1975 and NRC Regulatory Guide 4.13. Details of this testing can be found in NUREG/CR-3775.

! l l The radiation levels are presented as gross and net exposures. 'Ihe gross exposure includes
- naturally occurring background radiation, radiation levels resulting from a facility's operation, i and the exposure received during transport and storage of the TLD. Net exposures are obtained by subtracting an estimate of the exposure received by the dosimeters during transit from the l gross exposures. All exposures are nortpalimd to a 90 day quarter (standard quarter) and
{ reported in units of milliroentgens (mR). Station numbers for which no data are reported included ! stations which have been deleted, stations for which the TLD was lost during the quarter, or j stations for which the TLD was damaged. When control dosimeter data are unavailable, no net , j exposures are calculated. 4 1 Three sets of data are presented for each site. 'Ihe first set includes the TLD station number, its ] direction and distance from the site, the integrated gross exposure for the period, the net exposure normalized to a 90-day quarter (standard quarter), and the historical average and standard
- deviation for the station. All measurements for the current quarter are listed with their respective random and total uncertainties. The uncertainties are listed in the following format
5 l
i 2 X +- S.; U, where .X = value of the result S, = random uncertainty expressed as one standard deviation U, = combined total uncertainty The second set of data summarizes the average net exposure measured in each of the 16 standard windrose sectors around the facility, normalirM to a standard quarter. He third set of data summarizes the average net exposure measzed at three ranges of distances from the facility, normalized to a standard quarter. When average net exposures cannot be reported because of the l unavailability of the site's transit control dosimeter, the average gross exposures, normalird to a standard quarter, are reported in these two sets of data. The "Std.Dev." refers to the standard deviation of the measurements made in each sector and range, respectively. This report is one of a continuing series of technical reports covering the results and experiences of the operation of the NRC TLD Direct Radiation Monitoring Network. Suggestions on methods to improve the presentation or analysis of the data contained in this NUREG are appreciated and should be submitted to NRC Region I, 475 Allendale Road, King of Prussia, Pennsylvania 19406, A'ITN: Radiation Dosimetry Specialist. Data Analysis The analysis of the data for the third quarter indicated that at some of the monitored sites, the results for a few TLDs were outt.ide the range that is normally expected for those locations. A 1 net result is considered to be within the expected range if it is within plus or minus three times the standard deviation of the historical mean. He " historical range" column on the first page of l data for each site shows the mean and one standard deviation of previous net results for each 'ILD l
~
location. The result for any particular location may be within, above, or below this range. Some of the atypical results readily lend themselves to explanation, while others do not. A footnote is provided on the first data page for those sites for which one or more TLDs were found to be outside the expected range. The affected sites were Clinton, Pt. Calhoun, Pt. St. Vrain, Kewaunee/Pt. Beach, Peach Bottom, Susquehanna, Trojan, and %ree Mile Island, nere is no indication that any of the atypical results are related to facility operations. With the exception of Susquehanna and Three Mile Isi.=xi, there were no obvious causal agents that would account for the results outside the expected ranges. At Susquehanna, TLD no. I was higher than normal due to radiographic inspection of pipeline laid in the vicinity of this TLD. At nree Mile Island, the results for TLD numbers 25,29,30,45, and 49 are shown for two quarters because these TLDs could not be collected at the end of the second quarter. Other than at these two sites, none of the atypical results were more than 1 to 2 mR above the expected range. According to the contractor who exchanges the TLDs at Trojan, highway construction was underway during the third quarter near the location of TLD no. 3, and a considerable amount of
f ] 3 stone was hauled in and placed in that area. A higher radiation background may have resulted from placing large quantities of stone where formerly there was dirt or a covering of vegetation. The data for this location will be reviewed in subsequent quarters. , His example of a probable cause for the atypical result at Trojan serves to illustrate one among ; many possible explanations that have no relation to the monitored facility. Unfortunately, it is l often difficult to obtain such information. Weather is another example of a causal agent that could influence '11.D results. The amount of naturally occurring radon and its daughter products in the lower atmosphere is a complex function of the wind, the amount of precipitation, and the resultant saturation of the ground with rain water (or coverage by ice or packed snow). The higher concentrations of radon that sometimes occur as a result of a combination of weather-related circumstances can give rise to TLD results that are somewhat higher than normal. Some of these could fall slightly outside the expected range. Systematic uncertainties, most notably the calibration uncertainty, could influence the data by introducing a bias in the overall results. Some of the net results that otherwise would have been i near the limit of the normal range could therefore fall slightly outade this range. The atypical results at other sites noted in the report were carefully reviewed. The gross exposure data for the affected TLDs was consistent with previous quarters, while the transit dose in some cases was somewhat lower than normal. Since the transit value is subtracted from the gross exposure to arrive at the net exposure rate, a lower transit dose would cause the net exposure rates to be larger. Some of the net results that would have been near the limit of the normal range are therefore slightly outside this range. Examples are Clinton and Kewaunee/ Pt. Beach. The transit control for the latter was so low (more than a factor of 5 lower than any previous quarter) that it was considered anomalous, and therefore not used in the calculations. The data also were reviewed from the perspective of each TLD's proximity to the site, and whether any pattem of higher than expected exposures could be discerned. No such patterns were detected. Many of the affected TLDs were at relatively large distances from their respective facilities, with no indication of unusual results at locations closer to the facilities. Furthermore, there were no releases of airborne radioactivity from any of these sites at levels that could result in exposures offsite that would be discernible from the surrounding background radiation levels. Such releases, if they occurred, would be detected by other sensitive radiation monitoring instruments either at the point of release or at other on-site or off-site locations. The NRC TLD Direct Radiation Monitoring Network is intended to aid in the assessment of the radiological impact of an unusual condition, such as abnormally large releases of airborne radioactive material, but it will not be the primary indicator that releases have occurred. Sites Monitored Durine the Third Ouarter 1996 ne list is provided on page 223 of this report.
