Title	Missing Tritium Exit Signs
Event Description	The Federal Bureau of Prisons in Duluth, Minnesota reported the loss of generally licensed devices (self-illuminating tritium exit signs) as required by 10 CFR 31.5(a)(10) and 10 CFR 20.2201(a)(1). Four (4) tritium exit signs are assumed to be missing. A thorough search was conducted but failed to locate the missing signs. The serial numbers are known for 3 of the 4 missing signs; 309482 - 11.47 Ci, 309489 - 11.47 Ci, C601373 - 20 Ci. The licensee has notified R3 (Piskura). 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.
