AGREEMENT STATE REPORT - UNABLE TO RETRACT SOURCE
The following information was received from the Minnesota Department of Health (MDH), Radioactive Materials Unit via email:
"On July 2, 2025, MDH received an email stating that on July 2, 2025, at 1130 [CDT] the licensee had a source retrieval [issue] of a 35.64 Ci Ir-192 source in a SPEC 150 camera. The licensee's radiation safety officer (RSO) was notified that a radiographer was unable to retract the source to its fully shielded position during radiographic operations. The radiographer's assistant cranked the source out and realized that he had gone too far and notified the radiographer. The radiographer investigated the situation and observed the source was spooled on the ground. The radiographer alerted the RSO. The RSO informed all radiation workers to establish a 2 mR/hr boundary. The RSO and a staff member, who is trained in source retrieval, were able to crank the source back into its fully shielded position at 1203 [CDT]. The radiographer received 144.9 mrem whole body. The RSO calculated the radiographer received 526.27 mrem to the feet. The RSO received 4.5 mrem and the source retrieval staff received 0.3 mrem. MDH plans on conducting an investigation next week."
