The following information was received from the State of
Texas via e-mail:
On July 6, 2011, the Agency [Texas Department of Health] received a written report from the licensee's Radiation Safety Officer (RSO) that on June 27, 2011, there was a source disconnection at a temporary field site [Dralco, Inc] in Weatherford, Texas. Upon discovering the disconnection, the radiographers roped off the area at the 2 millirem/hour boundary and notified the RSO.
The RSO arrived on site and confirmed that the source was disconnected. The RSO performed the retrieval by removing the source tube from the camera, shaking the source out of the source tube and placing a lead shield and shot bag(s) over the source with the pigtail exposed. He reconnected the drive cable and the source was cranked back into the camera. The camera was disconnected so that the drive cable and the pigtail connectors could be inspected. No damage was noted and the camera was immediately returned to service.
The RSO stayed on site approximately one hour to make sure there were no more issues. The RSO stated that the radiographers had failed to connect the pigtail to the drive cable before cranking out the source. The RSO received a dose of 52 mrem. Corrective action includes the event being discussed at the next safety meeting, the radiographers (who were trainers) were instructed to pay attention to safety and the process of connecting the drive cable to the source.
