The following was received from Kentucky DThe following was received from Kentucky Department of Health Radiation Branch (KY RHB) via email:</br>KY RHB was notified by telephone on 9/3/19 that at approximately 1230 EDT on 8/30/19, while performing radiography in a pipe rack, radiographers were unable to retract a 38.7 Curie Ir-192 (AEA/QSA A424-9, Serial No. 82580G) source into the exposure device (QSA 880D Serial No. D11651) using the crank mechanism. During the retracting process the cover plate on the drive became loose, enabling the internal drive cable to depart the gear system in the handle of the drive cable mechanism. </br>Since the issue with the drive cable could not be repaired, the incident became a retrieval situation, and the crew made appropriate notifications to the Radiation Safety Officer, manager and on-site contact. The crew established a new 2 mR boundary as required and confirmed that the area was secure. The drive cable was removed from the handle, and the source was manually retracted into the exposure device. The source was secured in the exposure device at 1435 EDT. During the 2-hours while the source was exposed, there were no overexposures to the public.</br>The radiographer and assistant received exposures of 80 mR and 130 mR respectively and the manager received an exposure of 5 mR. It was determined that the root cause of the incident was that the crew did not properly inspect the equipment before commencing non-destructive testing activities. It was discovered that the drive cable handle was missing four of the six screws that secure the cover plate on. This caused the drive cable to slip off the gear and partially lift the cover plate. The drive cables were immediately taken out of service and replaced with properly functioning equipment.</br>Event Report ID No.: KY190009g equipment. Event Report ID No.: KY190009  +
