1 EIrlam 1 f The U. S. Nuclear Regulatory Commission (NRC) Direct' Radiation Monitoring Network is operated by the NRC in cooperation with participating states to provide continuous measurement of the ambient radiation levels around licensed NRC facilities, primarily power reactors. Ambient , mdiation levels result from naturally occurring radionuclides present in the soil, cosmic radiation - i constantly bombarding the earth from outer space, ant' the contribution, if.any, from the - monitored facilities and other man made sources. The 'vetwork 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. . This report presents the
- radiation levels measured around all facilities in the Network for the third quarter of 1997. A complete listing of the site facilities monitored is included. In some instances, two power reactor e facilities are monitored by the same set of dosimeters (e.g., Kewaunee and Point Beach).
' . All radiat ion measurements are made usi ng small, passi ve edtector cs alled thermoluminescent dosimeters (TLPs), which' provide a quantits;1ve measurement of the radiation levels in the area in which they att placed. Each site is monitored by arranging approximately 40 to 50 TLD 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
- 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 inWt study _of the following l
characteristics of the NRC dosimetry system; enerEy response, angular dependence, temperature and humidity sensitivity, fading, light dependence, 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- The radiation levels are presented as grose and net exposures. .The gross exposure includes naturally occurring background radiation, radiation levels resulting from a facility's operation,
- and the exposure received during transport and storage of the TLD. Net exposmes are obtained by subtracting an estimate of the exposure received by the dosimeters during transit from the gross exposures. All exposures are normalized to a 90-cay 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 l stations for which the TLD was damaged. When control dosimeter data are unavailable, no net l exposures are calculated. 7 Three sets of data are presented for each site. The 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 uncertaintiet. The uncertainties are listed in the following format: f 1

The third set of data l summarizes the average net exposure measured at three ranges of distances from the facility, normalized to a standard quarter. When average net exposures cannot be reported because of the
; unavailability of the site's transit control dosimeter, the average gross exposures, normalized to ,
L a standard quarter, are reported in these two sets of data. 'Ihe "Std.Dev." refers to the stancard j- 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 j of the operation of the NRC TLD Direct Radiation Monitoring Network. Suggestions on methods 4
.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 4

- Data Analysis o
'the analysis of the data for the third quarter indicated that at some of the monitored sites, the results for a few TLDs were outside the range that is normally expected for those locations. A -
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. The " historical range" column on the first page of , data ior each site shows the mean and one standard deviation of previous net results for each TLD location. The result for any particular location may be within, above, or below this rc.nge. Some of the atypical results readily lend themselves to explanation, while others do not. A footnote is e provided on the first data page for those sites for which one or more TLDs were found to be , outside the expected range. The aifected sites were North Anna, Oyster Creek, and Salem (NJ).
'Ihe results for Oyster Creek and Salem (NJ) were lower than expected. There is no indication that any of the atypical results are related to facility operations.
There were no obvious causal agents that 'would account for the results outside the expected ranges. LUnfortunately, it'is often difficult to obtain such information. Weather is an example of a causal agent that could influence TLD 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 i combination of weather-related clicumstances can'give rise to TLD results that are somewhat higher than normal.- Some of these could fall slightly outside the expected range.

l 3 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 near the limit of the normal range could therefore fall slightly outside this range. The atypical results at the sites noted in the report were carefully reviewed. The gross exposure data for the affected TLDs at Oyster Creek and Salem (NJ) were consistent with previous quarters, while *.he transit doses were somewhat higher than the typical values that were recorded through the second quarter of 1996. The change in transit doses may in turn be due to differences in the way the TLDs are handled by the contractor. Since the transit value is subtracted fro,n the gross exposure to arrive at the net exposure rate, a higher transit dose would cause the net exposure rates to be smaller. Some of the net results that would have been near the limit of the normal range are therefore slightly outside (below) this range. Several TLDs at the Erth Anna site were above the expected range. Most of the atypical results were no more than about I to 2 mR above the expected range. The TLD at location no. 27, however, was 3.5 mR above the expected range. The Virginia Department of Health, which is f a :ontractor for exchage of NRC TLDs at this site, also has a set of its own TLDs that are t.d.ariged quarterly. The individual within this agency who analyzes their T1.D data stated that there was no indication of unusually high results for the tiiird quarter. A review was also 1,erformed of the data collected by the licensee for the third quarter. This review did not reveal any data that corresponded to the unusually high readings of the NRC TLDs. The possibility remains that the NRC TLDs were exposed during transit due to proximity to a package containing a radiopharmaceutical or research isotope. It is within reason that a portion of the TLDs in the shipping container may have been exposed to a greater extent than others due to the orientation of the packages and due to the shielding effect that the TLDs closer to the sarface wculd have on those that were situated behind them. 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 the site, including two (36 and 37) that are uaed as upwind controls. The affected TLDs were scattered throughout nine of the sixteen standard windrose sectors surrounding the site. 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.
