Title	Guide Tube Disconnected with Radiography Source Not Retracted
Event Description	The following is a synopsis of the information received during phone notification: On March 31, 2018 at about 1630 CDT, radiography was being conducted on an offshore platform at the +10 foot level. During an exposure the technician (radiographer) noted that the source did not appear to be retracting. The technician observed that the guide tube had become disconnected. The technician lifted the guide tube to align the source cable and the assistant (radiographer) cranked in the source. The technician estimated he held the guide tube for 2 to 5 seconds for the source to be retrieved. The whole evolution took an estimated 30 to 60 seconds. The technicians then shutdown the operation and called the Radiological Safety Officer (RSO). The technician and assistant's whole body dosimetry was read and the technician received 7 mR, and the assistant no millirem (mR). The device that malfunctioned was a Source Product Equipment Company (SPEC) model 150 with a model G60 source of IR 192 with an activity of 77 curies. The RSO calculated the technician's dose to the hand to be 630 mR. The RSO stated that since this is an offshore operation he was reporting this event to the NRC under a reciprocity agreement. The RSO stated that he would be making a report to the state of Louisiana, and to NRC Region 4 as a courtesy.
