On April 10, 2023, the licensee reported to the Agency that on April 7, 2023, one of its QSA Delta 880 industrial radiography exposure devices (camera) had fallen approximately three feet onto the source guide tube at a job site in Orla, Texas. The camera severed the guide tube and the source pigtail was disconnected from the drive cable. The source was 72 curies of iridium-192. A boundary was set at 2 millirem by the radiographers and an individual authorized on their license was dispatched to the site and retrieved the source. The retriever's dosimeter indicated a whole-body dose of 2.6 rem. The licensee has reported initial calculations for the retriever's hand dose to be 385.9 millirem. The two radiographer's self-reading pocket dosimeters indicated doses of 180 and 150 millirem. All of the equipment is being sent to the manufacturer for evaluation. An investigation into this event is ongoing. More information will be provided as it is obtained in accordance with SA-300.
