A representative for the Air Force Master Material License reported that a device containing a 10 millicurie Nickel-63 source is lost. The device containing the source is a Ion Track Vapor Tracer. The device was last inventoried in storage at Patrick Air Force Base at Cape Canaveral,
Florida. The date of the last confirmed inventory of the device and source was in 2002. The Air Force has exhausted all its efforts to locate the source and declared it permanently lost following the an inventory in August 2005. The source serial number is s/n 01024892704. Other sources kept at the same storage location as the missing device have been moved to a more secure location. The licensee does not believe that the device was
stolen. The licensee has notified NRC Regional Inspector (R. Browder).
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.
