| Title | Agreement State - Radiography Camera Source Would Not Retract |
| Event Description | The following information was provided by the State of Texas via email:
On August 14, 2014, the Agency [Texas Department of State Health Services] was notified by the licensee's Radiation Safety Officer (RSO) that on August 13, 2014, a radiography crew using a 50 foot crank out device could not retract a 54 curie iridium-192 source to the fully retracted and locked position in a QSA 880D exposure device (camera). The RSO stated the radiographer had completed an exposure at a temporary field site and was retracting the source when he felt the resistance to movement in the crank out handle disappear and he could no longer move the source. The radiographer noted the dose rates were still higher than those for a fully shielded source. The radiographer contacted the RSO and increased the control area. The radiographer placed two bags of lead on the guide tube where he believed the source was located. The RSO stated the radiographer was in the area of the source for just a few seconds. The radiographer checked his self reading dosimeter after placing the lead at the source and found it off scale. The RSO and a recovery team went to the location to retrieve the source. The RSO had additional lead placed on the guide tube and the dose rates at the crank out device dropped to less than 2 millirem per hour. The RSO disconnected the drive cable housing from the broken in two at crank out device. The RSO grabbed the drive cable inside the drive cable housing with a set of pliers and was able to pull the drive cable and return the source to the fully shielded position. The personnel dosimeter for the radiographer who had approached the guide tube was sent to the licensee's dosimetry processor for processing and the radiographer has been removed from all work involving exposure to radiation until the results for their badge has been received. The RSO stated that based on the exposure rates and the time the radiographer was in the area of the source he did not believe the radiographer received a significant exposure from the event. The RSO received 8 millirem by pocket dosimeter from the event. No other individuals received any significant exposure in this event. The crank out and drive cable will been sent to the manufacturer for inspection. The RSO stated he examined the drive cable, but did not see anything that would indicate why the cable failed. The RSO stated they performed a flex test of the drive cable and it passed. The RSO stated the camera and guide tube were inspected and returned to service. Additional information will be provided in accordance with SA-300. Texas Incident #: I-9219 |
