The following information was received via email:
While using a QSA Global 880D radiographic exposure device, the licensee's crew was unable to move the drive cable forward or backward. It appeared that the source was moved slightly out of the fully shielded position when the device was unlocked prior to the attempt to crank out the source. The crew was unable to retract the source and lock the device. A licensee employee trained in source retrieval was sent to the site. The employee disassembled a portion of the drive cable which gave him access to manually pull the drive cable in the direction that would retract the source. The cable was moved approximately 1/4 inch. This placed the source in the fully shielded position and the source was locked in the shielded position.
Only licensee personnel were potentially exposed to radiation from the device during the incident. Licensee personnel stated that they did not step in front of the camera at any point during the incident. The radiographer used the survey meter to determine where to stand to receive the least exposure while checking the camera. At one point he reached forward with the survey meter and measured 200 mR/hr at the front port of the device. Dose estimates for licensee personnel associated in the incident were well below the limits for occupationally exposed individuals.
