Title	Non Agreement State Report - Stuck Source Retrieved
Event Description	The following summary was provided by the licensee via phone and email: At approximately 2100 CDT on 04/16/23, the radiography crew began to setup a radiograph using a SPEC-150 camera on the East Cellar Mezzanine deck on an offshore oil rig near the state of Louisiana. The radiograph began at approximately 2120 CDT. After a 3 minute exposure, the crew attempted to retrieve the source back to its shielded position in the camera. During this time, the crew noticed that the camera's source lock/plunger was not engaging. After several attempts to expose and retract the source with hopes of a proper lock engagement, the crew determined that the source was unable to return to the shielded position. The crew expanded the 2 mR/hr boundaries on all affected areas and decks with a survey meter in hand. After unsuccessful attempts to retrieve the source, the technician was finally able to fully unscrew the crank hex out of the handle. Once the inside wire was exposed, the technician manually pulled the wire and was able to get the source back into its fully shielded and locked position. No crew members were injured, and there were no overexposures during this incident.
