Title	Missing Sources
Event Description	While licensee was conducting their semi-annual inventory of sources they discovered that two sources were unable to be located. One source, 13.9 milliCuries of Ni-63, was believed to be a double entry in the inventory log, however, that is not confirmed at this point. A second source, 10.4 microCuries of Am-241, is also missing. The RSO has been notified. The licensee is continuing to search for the missing sources. A meeting was held by the licensee to review their inventory control procedures and see how this can be prevented in the future. 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.
