| Title | Agreement State Report - Source Disconnect and Retrieval |
| Event Description | The following information was provided by the State of Texas via email:
On November 22, 2010, the [Texas Department of Health Services] Agency received notification from the licensee that it had experienced a source disconnect yesterday, November 21, 2010 at approximately 1200 CST. The licensee stated that a two person radiography crew was working at a refinery near Alvin, Texas when they experienced a source disconnect. The radiographers were using a QSA Global device (Model: 660-B) that housed a 67 curie, Selenium (Se) - 75 source. According to the licensee, the radiographers had made 24 exposures and on the 25th exposure, the source disconnected from the drive cable. The radiographers were able to crank the cable back into the camera, but the source remained out. The radiographers contacted their Site Radiation Safety Officer (SRSO). The SRSO, who is authorized to retrieve sources, traveled to the site and returned the source to the camera at approximately 1700 CST. The radiographers at the site waited for the SRSO to arrive while verifying the 2 millirem per hour boundary, and keeping constant security on the radioactive material. According to the licensee, the highest exposure measured by the radiographers' pocket dosimeters was that of the SRSO, whose dose was measured to be 45 millirem for the event. The licensee stated that they were unsure why the source disconnected from the drive cable. However, the licensee has contacted the manufacturer, and will send the entire set-up (camera, guide tube, drive cable, etc) to the manufacturer for inspection and repair. TX: I-8798 |
