Subject:
RADIOGRAPHY OVEREXPOSURE The Louisiana Radiation Protection Division notified Region IV of a significant overexposure to a radiographer while he was performing radiography on May 21, 1993. This overexposure was confirmed by processing the radiographer's TLD, which showed a 27 rem whole body exposure. This meets the criteria for an Abnormal Occurrence Report.
The incident occurred while radiography was being performed by radiographers in personnel baskets, high up the side of a large steel tank. Proper radiation surveys of the camera were performed by the radiographers; however, the survey instrument had been dropped earlier in the day and may not have been operating properly. The radiographers did admit they were not locking the source in the camera after each shot as required by Louisiana regulations. The overexposure occurred when the i
radiographer and camera were being carried together in a personnel basket, and the crankout rotated and partially exposed the source. The radiography camera was a SPEC 2T, which contained a 100 curie, iridium-192 source. Immediate processing of the radiographer's TLD disclosed the overexposure.
The radiographer was placed under medical evaluation and blood tests are currently being performed. The Louisiana Radiation Protection Division is considering escalated enforcement action.
Region IV has notified NMSS and SP. Region IV received notification of this event at 3:00 p.m. on June 1, 1993, from the Louisiana Radiation Protection Division.
