| Title | Agreement State Report - Lost Tritium Target Sights |
| Event Description | The following report was received by the State of California via email:
On August 12, 2015, [the licensee's], Alternate Radiation Safety Officer, contacted the [State of California Radiologic Health Branch] Brea Radioactive Materials office to report lost Tritium [target sight] sources. After receipt at the [licensee] facility, 18 sources were no longer accountable in the inventory process. [The licensee] noted that, sometime between August 6 and August 10, the loss was discovered by one of the [licensee's] authorized users while performing an inventory of sources in the shipment to ensure that the proper number of sources were received. The lost sources were SRB Technologies, Inc. model AR Tritium [target sights] generally licensed sealed sources (these sources do not have serial numbers) with 0.8 Curies of tritium, for a total of 14.4 Curies. After the missing sources were discovered, SRB Technologies was contacted to determine the number of sources that were supposed to be contained in the package. When SRB Technologies personnel notified [licensee] that the package contained 36 sources, as listed in the included packing slip, [licensee] personnel conducted a search of the facility to find the sources. When the search did not find the missing sources, it was determined that the missing sources were likely to have been thrown away with the packaging in their trash bin, which had already been emptied on the morning of August 7, 2015. The Irvine facility of Waste Management was contacted to determine if it was possible to search the trash bin, but they were told that was not possible and the trash was most likely to have been dumped in a landfill. Once the investigation into the loss of sources was completed on August 12, 2015, the licensee determined the sources to be lost, most likely in a landfill. After the determination that the source were lost was made, [the licensee] then contacted the [State of California] Brea Office to make the official report. California 5010 Number: 081215 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.
