| Title | Radiography Source Failed to Retract |
| Event Description | During retraction of the source following an exposure inside a storage tank [at the BP Refinery, Whiting, IN], the radiographer noted the source did not retract with the drive cable as survey readings indicated the source was still exposed. An immediate call was made to the local RSO [Radiation Safety Officer], who is source retrieval trained, to report the issue. Barricades were continuously monitored while waiting for his arrival. Upon arrival and evaluation of the situation, the local RSO determined a source disconnect had occurred due to a possible broken drive cable. Source retrieval procedures were then enacted with the source safely returned to the shielded position in the exposure device at approximately 1400 CDT. The exact cause of the event is not clear at this time and the drive cable and connector are being sent to the manufacturer for evaluation.
Equipment involved: QSA Ir192 model A424-9 source assembly with approximate activity 84 Curies; QSA model 880 Delta exposure device and associated equipment (drive assembly and guide tube). Approximately 4-5 individuals were involved in the retrieval process with the RSO (Authorized Source Retriever) indicating he received the highest exposure, as recorded on pocket dosimeters, of 25 mrem. |
