Title	Agreement State - Missing Moisture Density Gauge
Event Description	Zell's former consultant HP (Health Physicist) informed DEP (Department of Environmental Protection) that [a] nuclear gauge was discovered [to be missing] while performing a 6-month inventory on January 13. An unsuccessful search for the missing nuclear density gauge (Humboldt Model 5001 EZ122; Ser. No. 5375) was concluded on January 14. The licensee notes the gauge cannot be accounted for at this time. Gauge contains about 10 milliCuries Cs-137 and 40 milliCuries Am-241 (as an Am/be neutron source). PA Event #: PA100001 Notified R1DO (Dimitriadis) and FSME (Lewis). 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.
