| ENS 42931 | 30 March 2006 18:00:00 | 10 CFR 20.2201(a)(1)(i) | Loss of Two Americium - 241 Sources Due to Aircraft Mishap | A representative from the Air Force Master Material Licensee reported that a U.S Air Force F-16 aircraft with a LANTIRN (Low Altitude Navigation and Targeting IR for Night) , targeting and ranging device attached to the aircraft, crashed in Utah's Great Salt Lake test range area near Hill AFB. The LANTIRN pod contained two 4 microCurie Am-241sources (a total of 8 micro Curie). The USAF is evaluating whether or not a recovery effort will take place. The licensee discussed this issue with Rachel Browder NRC Region 4. 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. |
