Title	Radiography Equipment Failure
Event Description	The following information was provided by the licensee via phone: On June 30, 2025, the licensee was performing radiography at a temporary jobsite at the HF Sinclair Refinery with a SPEC-150 camera using a 1.474 Tbq Ir-192 source. With the source extended, a crankout came into contact with a hot pipe, melting the crankout and damaging the source cable. At 1136 MDT, the radiographers determined the source could not be retracted. The radiographers extended the boundary and established a watch to prevent unauthorized entry. A technician certified for source retrieval used a source retrieval kit and successfully retracted the source at 1203. The crank cable had to be pulled directly due to the cable damage. The maximum dose to any of the radiographers was 9 mrem. No members of the public received any exposure due to the event.
