AGREEMENT STATE REPORT - UNABLE TO RETRACT SOURCE
The following information was received from the State of Texas via email:
"On August 12, 2018 at approximately 1135 [CDT]., the licensee notified the Agency [Texas Department of State Health Services] that one of its radiography crews had experienced a source disconnect. The event occurred on August 11, 2018, at approximately 1200 [CDT] at a temporary job site near Whitsett, TX. The device involved was an INC IR-100 (SN: 6792) containing a 91 curie iridium-192 source (SN: ZH0109). The crew had set up the device and performed a procedure shot and everything functioned properly. They performed the first shot of the job and the source would not retract into the device--it felt as though it had stuck on something. After a second unsuccessful attempt, the source was cranked back out into the collimator, boundaries set, and an authorized person came to the site and performed the retrieval. The drive cable and source were both new. There was no observable cause for the failure. The device and associated equipment will be sent to the manufacturer for evaluation. Per readings from all three individuals' self-reading pocket dosimeters, there were no overexposures. The source retriever's dosimetry badge is being sent for processing. An investigation into this event is ongoing. More information will be provided as it is obtained in accordance with SA-300."
