| Title | Source Disconnect from Radiography Camera Drive Cable |
| Event Description | The Agency (State) was notified (at 1645 CDT) by the licensees RSO that they had a source disconnect and that the source was later retracted. The event involved an INC IR-100 camera containing a 94 curie Ir-192 source. The source was in use for about one week, about 6 jobs. A local Texas inspector went to the site to investigate the event.
The licensee later notified the Agency (State) that in this case, the connector crimped fitted on the source pig tail had separated from the source drive cable. The two individuals who returned the source to the camera housing received 425 millirem by self reading dosimeter for one worker, and between 750 and 800 millirem calculated for the other worker. The RSO stated that neither worker exceeded the annual DDE limit. TLD's for the workers involved have been sent to their processor and the results should be back on 3/9/09. The State of California has been informed of the event. On March 13, 2009, the RSO notified the Agency (State) that the radiography camera had been packaged and will be returned to the manufacturer today. Texas Incident # I-8614 UPDATE FROM ART TUCKER VIA EMAIL TO JOHN KNOKE AT 1237 0N 04/14/09 [The State] received exposure reports for two workers involved in the source retrieval. The support individual received 299 millirem DDE, and the individual who actually retrieved the source received 502 millirem DDE, and 425 millirem calculated to the hand. Notified FSME (Angela McIntosh) and R4DO (Jack Whitten)
Report received via e-mail: The [State of Texas] received the following information from the manufacturer of the source device: [The] license, Industrial Nuclear Company [INC], was notified by Desert Industrial X-ray that there had been a source disconnect of 97 curies, source S/N-N597 on March 5, 2009. Source and connector was received at Industrial Nuclear Co, Inc on March 13, 2009. Upon inspection of source connector [on] S/N- N597 that was received from Desert Industrial X-ray, INC found no evidence [of] physical damage. The cable appeared to have some stretching but not any more than would be expected after the pull test. Dimensions were performed on all previous inspected source assembly components and found to be within design limits. All INC source connector assemblies in inventory (from the same manufacturing date) were re-load tested and all passed. INC has to date never had a Source Connector come off in pre-inspection or after it was put in use. INC has not been able to discover just how this might have happened. In the report the licensee stated the connector crimp failed. INC has tried to recreate this event but [has] had no success in doing so. The licensee said the source had been in use for one week [and] if the source connector crimp was bad it should had failed on the first day. The licensee has not reported any additional problems associated with their exposure devices. Notified R4DO (Lantz) and FSME EO (McIntosh) |
