Overexposure of an Industrial Radiographer

A radiographer was exposed to a 3.81 TBq (103 Ci) iridium-192 source while conducting industrial radiography. The individual’s whole body dose was evaluated by a licensee consultant to be 30 cSv (rem) as a result of a single event. Confirmatory calculations by the regulatory agency supported the exposure estimate.

The event occurred when the radiographer failed to successfully retract the source to its shielded position following a film exposure. The radiographer entered the restricted area without performing the required radiation survey. The radiographer’s alarming dosimeter failed to alarm. While in the restricted area, the radiographer recognized that the source was still exposed and immediately exited the area.
