Title	Lost Americium-241 Source
Event Description	During a visual inspection of a source storage area at the Wright-Patterson AFB, 88th Medical Group, the licensee was unable to locate a 12 mCi Am-241 source. A rad survey was conducted but the source was not located. A search of the nuclear medicine area was performed with negative results. The source was last leak tested in July, 2002, then placed in storage. The last visual inspection where the source was identified was performed in September, 2009. The source was slated for disposal. The licensee is searching through their records to determine if the source, in fact, was sent to a disposal facility. The licensee notified Jackie Cook, R4DNMS. 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.
