Title	Lost Electron Capture Detector Containing Ni-63 Source
Event Description	The licensee reported that a electron capture detector (Perkin Elmer model # 0330-0119, serial # 2161) is declared lost as of 05/16/06. The detector contains a sealed 10 milliCi Ni-63 source (Ni-63 plated foil). The detector was being stored in a lab area used by the previous RSO and was thought at one time to have been returned to the manufacturer due to obsolescence of the detector. The detector was discovered missing in December 2005 and is believed to have been discarded in general waste in Spring 2005 during a reorganization of the facility. 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.
