The following information was provided by the State of
Utah via email:
At approximately 2100 MST on November 26, 2015, two radiographers, working for QTI [Quality Testing and Inspection], were completing radiography operations [at a job site in Provo, UT for Dragon Manufacturing]. When the exposure was completed, the source was withdrawn to the camera but was not fully retracted into the shielded position when the locking mechanism was engaged. The radiographers could not move the source or cable. The source was secured, personnel exited the affected area and the radiographers notified the Radiation Safety Officer (RSO). Temporary lead shielding was placed over the affected camera. Licensee personnel waited in low dose areas until the RSO arrived at the site. Licensee personnel maintained visual control of the affected area.
After performing radiation surveys of the camera, the RSO withdrew and inserted the source into the source changer. The RSO locked the source inside the source changer and transported the radiography equipment to the Licensee's facility.
The source changer, camera and associated cables were removed from service and transported to the licensee shop. Radiation exposures (from self-reading dosimetry) to the licensee personnel were approximately 10 mRem. The RSO's dosimeters indicated an exposure of approximately 40 mRem. More information will be provided in coming days.
The licensee notified the State of Utah at 1200 MST on 11/27/2015.
The camera was a model IR 100, serial number -4122, which contained a 93 curie Ir-192 source, serial number - Z825.
