AGREEMENT STATE - RADIOGRAPHY SOURCE FAILED TO RETRACT
The following was received via email:
The 48 Ci Iridium-192 source in an INC IR-100 radiography camera, sn 6617, failed to retract in that the safety latch popped up prematurely, locking the source in the un-captured position outside of the radiography camera. The radiographer approached and surveyed the radiography camera, depressed the latch, returned to the cranks and returned the source to the safe position. Upon examination of both the radiography camera and the cranks, no damage or excessive dirt was detected that could explain this type of failure. The radiographer and assistant did not pick up any excessive radiation exposure as a result of this incident. Note: the operations manual for this instrument indicates that this type of failure could occur and instructs the user/radiographer in the steps to take to correct the problem. These steps, mentioned above, were taken by the radiographer.
This event occurred at Shell Oil Refinery in Martinez, California.
California report number 122309.
