| ENS 42794 | 22 August 2006 00:00:00 | Agreement State | Agreement State Report - Radiographic Camera Disconnected Source | The State provided the following information via facsimile: This event involved a Source Production & Equipment Company radiographic exposure device (model SPEC 150, serial number 948; with sealed source model SPEC G-60, serial number NH0807). The activity contained in the radiographic exposure device at the time of the incident was 4.912 terabecquerels (133 Ci) of Iridium-192. The radiographer noticed that the crank turned out more turns than normal when he exposed the source. He then realized that the guide tube was not connected tightly to the device. The radiographer cranked the source in with the guide tube not connected. The pigtail hit against the radiographic exposure device and disconnected. The radiographer followed the licensee's emergency procedures and controlled the area until the radiation safety officer arrived. The radiation safety officer began and completed the source retrieval procedures without further incident. The licensee contacted the manufacturer regarding the disconnect. The manufacturer informed the licensee that when the source was outside the guide tube, and oriented 90 degrees to the travel direction of the cable, the source can disconnect. Event Location: Chevron Refinery VGO Unit, 2351 N 1100 W, Salt Lake City, Utah 84116 The Utah Division of Radiation Control was notified by the licensee in a telephone call on August 22, 2006.
