Title	Potentially Lost Depleted Uranium Shipping Safes
Event Description	The licensee recently performed a physical inventory of the depleted uranium "safes" used for shipment of Technetium-99m generators. These safes weigh about 45 lbs each and are used to provided shielding during the Tc99m shipments. Of approximately 3200 safes possessed by the licensee, 145 could not be located. The licensee is continuing its investigation and has expanded the search area within other buildings in the 20 acre facility. The licensee is also investigating possible inventory record keeping errors associated with the inventory tracking program. The licensee has informed the NRC R3 (Gattone) of the missing safes. 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.
