| Event Description | The following report was received from the State of Arizona via email:
At approximately 9:00 AM September 13, 2012, the [Arizona Radiation Regulatory] Agency was informed that the Licensee had a Humboldt Model 5001, SN 3920, portable gauge stolen from the back of a truck. The theft occurred between 9:00 PM September 12, 2012, and 6:00 AM September 13, 2012. The gauge was locked in a 16 gauge steel box bolted to the bed of the truck which was parked unattended at an employee's resident. The gauge contains 370 MBq (10 mCi) of Cesium-137 and 1.62 GBq (44 mCi) of Am:Be-241. El Mirage PD is investigating and has issued report number 12-09000902. The Agency continues to investigate this event. The Governor's Office, the States of CA, NV, CO, UT and NM and Mexico, US NRC, and FBI are being notified of this event. Arizona Event Number: 12-020
NOTE: The following information was originally provided as a new report by the Arizona Radiation Regulatory Agency. After additional information was obtained on 2/1/13 all information was combined into the original report concerning this event. The following information was received from the Arizona Radiation Regulatory Agency via email: The Agency [Arizona Radiation Regulatory Agency], in checking a scrap metal shipment being returned to Glendale, Arizona from California, found a source rod from a moisture density gauge. No other parts of a moisture density gauge were identifiable in the shipment. Based upon experience, it is estimated that the source contained approximately 8 millicuries of Cesium-137. It was confirmed in the field that Cesium-137 was the only isotope present. The Agency was unable to locate any identifying markings with which to trace the source. The Agency has taken possession of the source and has stored the device in a secure location. The Agency continues to investigate this event. This notice is being provided to the State of California, US NRC, and FBI. Arizona Event Report: First Notice 13-005. Notified R4DO (Walker). Notified FSME Events Resource via E-mail.
The following was received from the Arizona Radiation Regulatory Agency via email: The Agency, in checking a scrap metal shipment being returned to Glendale, AZ from Taiwan through California, found a source rod from a moisture density gauge. No other parts of a moisture density gauge were identifiable in the shipment. The manufacturer, Humboldt, estimated the source as approximately 10 millicuries of Cesium-137. We did confirm in the field that Cesium-137 was the only isotope present. Based on the identifying numbers found on the source rod this is part of Humboldt Model 5001, SN3920, reported stolen September 13, 2012. See First Notice 12-020 sent out September 14, 2012. The Americium-241 source has not been located. The Agency has taken possession of the Cesium-137 source and will store it in a secure location. Arrangements for proper disposal are being made. The Agency continues to investigate this event. This notice is being provided to the State of California, US NRC, and FBI. Arizona Event Report: Supplemental Notice 13-005. Notified R4DO (Walker) and ILTAB (Johnson). Notified FSME Events Resource and Mexico via E-mail. THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source. |
