| Title | Unable to Retract Source Into Radiography Exposure Device |
| Event Description | The following information was received by the Iowa Department of Public Health via e-mail:
At 0229 CDT on 06-14-22, the Assistant RSO (ARSO) received a phone call from one of the radiographers involved stating that he was working at a temporary jobsite and was unable to fully expose the source into the guide tube/collimator (Device Model: QSA 880D, Source Model: QSA A424-9, Source Activity: 80.8 Ci). Upon noticing the resistance, the radiographer extended his Restricted Area boundaries, notified the on-site personnel to maintain clearance of the area and proceeded to contact the ARSO. During the phone conversation, the ARSO was able to guide the radiographer through disassembly of the crank body to the point that he could manually pull the drive cable and retract the source into a fully shielded position within the exposure device. Once the source was successfully locked into the exposure device and the appropriate surveys were completed, the ARSO instructed the radiographer to perform an inspection of the drive cables and guide tube to look for the presence of any bends, kinks or dents that could have contributed to the binding of the drive cable. It was at this point that the radiographer noted an area on the drive cable sheathing that appeared to be melted on the `retract' side of the drive cable assembly. At this point (approximately 0254 CDT), The ARSO contacted the PROtect, LLC RSO and informed him of the details of the incident. A follow-up Corrective Action Report and additional detail regarding the cause of the event will be submitted to the State of Iowa within 30 days.
