On February 9, 2010, the Agency [Texas Department of Health] was notified by the licensee that while performing radiography with a 22 curie
Iridium (Ir)-192 source, the source could not be retracted into the camera. The device is an Amersham 660B camera. The radiographer noted that when he returned the source to the camera, the auto locking mechanism failed to activate. The radiographer then cranked the source back out and tried again to locked the source in the camera. The locking mechanism failed to lock. The source drive cable was left in the position where the source should be shielded. The radiographer performed a dose rate survey on the guide tube. He found the dose rates near the end of the guide tube were elevated. He contacted his Radiation Safety Officer. An individual listed on the license to perform source retrieval went to the location and retrieved the source. No over exposures were reported. An inspection of the source pig tail and drive cable found that the connection of the drive cable to the source pig tail failed because the ball on the drive cable side of the connection had broken off from the drive cable.
