The following information was obtained from the State of
Texas via email:
On the morning of August 17, 2009, a 79.1 Curie Ir-192 source in a Sentinel Model 880 exposure device (S/N D5517) could not be retracted into the fully shielded position. After several attempts to back the source out, it was surmised that the source remained at the end of the source tube and the Radiation Safety Officer (RSO) was notified. A 2 mR/hr line was established by the radiographers and the licensee's report indicated that visual surveillance was maintained at all times. The RSO then utilized additional shielding and remote handling tools to retrieve the source and place it into another camera. It was determined after the recovery that the ball shank broke from the drive cable leaving the source pigtail in the source tube. The RSO reported that all personnel were monitored with direct reading devices and no exposures exceeded regulatory limits.
