Type of event:
radiography accident
Description:
An accidental overexposure occurred at a facility using a 55 Ci Co-60 source for industrial radiography in an enclosed room. In place of a broken interlock access control system, two fixed radiological sensors with visual alarms were being used. A worker was in the room using a dosimeter with an acoustic alarm and a radiometer, but these had been failing occasionally. The worker missed the visual alarms from the fixed sensors and was in the room with the source exposed for 10-15 minutes. The worker's dosimeter indicated a dose of 71.8 rem. On 29 October the worker was sent for medical examination.
