Title	Agreement State Report - Possible Lost X-Ray Analyzer
Event Description	The following was received from the State of California via email: On May 5, 2010 the California Radiologic Health Branch (RHB) was informed by the alternate Radiation Safety Officer (RSO) of Chevron USA that they may have lost a Niton, XLP 818, S/N 13354, containing a 30 mCi Am241/Be sealed source. According to the alternate RSO, the Niton XLP was lost and was reported to him by the Material Inspection Group supervisor on April 29, 2010. This incident was not reported to RHB because the licensee was looking for the Niton XLP until the date of this report. CA Report #: 050610 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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source
