v t e ENS Event
22:06 Mar 3, 2009
Title	Failure to Fully Retract Source of Radiography Camera
Event Description	Radiography technicians were performing pipeline corrosion shots on piping in the North Slope of Alaska when they inadvertently locked the source outside of the shielded position in the camera while retracting the source. The technicians were using an Industrial Nuclear Corporation (INC) IR-100 camera which contains a nominal 120 Curie (original strength) Ir-192 source. When the technicians realized what had occurred, they immediately cordoned off the area and requested help. A trained camera technician arrived and, after shielding the source, was able to manipulate the key lock and retract the source into the safe (shielded) position. The highest radiation reading observed behind the camera was 40 mR/hr. Exposures to all personnel involved in the recovery of the source was less than 20 mR. Since the radiography was being performed in a remote location, there was no chance of exposure to any members of the general public. Currently, the camera has been removed from service and is being sent to INC for inspection and maintenance. * * RETRACTION FROM KEENAN REMELE TO JOE O'HARA VIA E-MAIL ON 3/4/09 AT 1443 * * * After receiving all the reports by the parties concerned it was not a malfunction of the exposure device that caused this event. The event occurred due to snow and ice build up in the locking mechanism and the radiographer turning the key inadvertently. This report will be forwarded to Region IV. Notified R4DO (Proulx) and FSME (McIntosh)
