Title	Lost Am-241 Source
Event Description	While conducting an inventory, the licensee was unable to locate a Standard Reference Material Electro-Plated AM-241, 0.079 uCi source that is used for calibration. It is believed the source may have been disposed as radioactive waste or transferred to another facilty. The licensee will continue searching for the missing source. 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.
