| ENS 55940 | 14 June 2022 07:29:00 | Agreement State | Unable to Retract Source Into Radiography Exposure Device | 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. Reporting requirements: 30.50(b)(2)(ii) - The 24 hour report of an event where required equipment is disabled or fails to function as designed when the equipment is required to be available and operable when it is disabled or fails to function.

| ENS 55939 | 13 June 2022 19:15:00 | Agreement State | Damaged Radiography Guide Tube | The following information was provided by the Kansas Department of Health and Environment via email: On June 13, 2022, at approximately 1415 CDT the licensee experienced an incident with the 9 Ci Ir-192 source in their 880 Delta radiography camera at their Lenexa, Kansas office location. They reported that during routine maintenance, the source became restricted in the source tube while cranking the source back into the shielded position. When the source was being retracted back into the camera, the cart on which it was sitting shifted. This put the guide tube into a bind which restricted the source from easily being returned into the camera. The Radiation Safety Officer (RSO) was immediately notified and arrived shortly thereafter to evaluate the situation. The licensee reported that once they realized it was just the position of the source tube putting the source in a bind, they were able to move the cart back to the position that then allowed them to retract the source back into the shielded position of the camera. The licensee reports that the source was exposed for no more than three minutes. The Kansas Radiation Control Program is currently performing a reactive inspection on June 14, 2022, and additional information will be provided at a later date. |
