POSSIBLE RADIOGRAPHY OVEREXPOSURES On February 26, 1997, the licensee reported a possible radiation overexposure to a radiographer, although preliminary information suggests
{
that the radiation exposure may have been received by the radiographer's l
thermoluminescent dosimeter (TLD) and not by the radiographer himself.
l The radiographer had worked at a temporary job site in Indiana.
l l
The TLD used by the radiographer, when processed, showed a dose range of j
240 to 510 rems (2.4 to 5.1 sieverts [Sv]). The TLD processor indicated that the dose measurement was considered to be a valid exposure to the badge.
The licensee has. investigated the possible overexposure and believes that it may not be valid for several reasons:
The radiographer worked for 9 days. January 2-9, 1997, and his self-reading dosimeter doses indicated an exposure of about 45 millirem (,45 millisieverts [mSv]) during that period.
The radiographer was interviewed and reported that there were no incidents or problems that might account for the high exposure, and that he has not felt any ill effects or symptoms since his work in January 1997.
The radiographer's helpeca@ rata 90 Bet /DhW1 deceived a radiation dose 050054 of about-70 millirem (.70 millisieYerts [69 ]) during the time period mSv involved.
ZE ( W L 0334 The licensee also intends to hheMkaNxamination and blood evaluation performed on the radiographer to determine if there is any medical evidence of an overexposure.

A Region III (Chicago) radiation specialist will conduct an inspection at the licensee's site on February 27, 1997, to review the circumstances surrounding the possible overexposure. Regional personnel will interview i
the radiographer, who was a temporary employee and lives outside the region.
j i
The States of Indiana and Wisconsin will be informed. The information in this preliminary notification has been reviewed with licensee management.
1 The licensee reported this incident to the NRC Operations Center at 4:32 p.m. CST on February 26. 1997. This information is current as of 9:00 a.m. on February 27, 1997.
