Title	Agreement State Report - Radiography Camera Source Failed to Retract
Event Description	The following information was received via E-mail: Desert NDT, LLC dba Shawcor (Shawcor) reported that a 3.15 TBq (85 Ci) Ir-192 sealed source (SPEC model G-60, serial #YJ2608) had disconnected from a drive cable connected to a SPEC model SPEC-150 radiography exposure device (serial #786) at a temporary job site in Watford City, ND on 11/15/2017. Upon completion of an exposure, the radiography crew performed a radiation survey while approaching the exposure device. At approximately 35 feet from the device, they noticed an elevated reading of approximately 20 mR/hr. At this point, the crew determined the source had not retracted into the safe, shielded position. The crew moved away from the device, secured the area, maintained a 2 mR/hr barrier and contacted the Branch Manager. The Branch Manager, who is trained in source retrieval, responded to the site. He successfully recovered the source following Shawcor established procedures. The Branch Manager inspected the exposure device and associated equipment. He determined no damage had occurred to the exposure device, guide tube, and/or crank assembly, rather the drive cable was not properly connected to the source pigtail. At no time during the event did the radiography crew member's pocket dosimeters go off-scale. In response to the initial notification, the North Dakota Department of Health requested the licensee send the exposure device and associated equipment involved in the event to the manufacturer for further evaluation.
