Title	Agreement State Report - Lost Tritium Exit Sign
Event Description	On December 5, 2006, the licensee reported that an exit sign, currently containing approximately 5.5 Ci of H-3 was apparently lost or inadvertently disposed during remodeling of the University Library in October 2006. This sign was distributed by 'Self Powered Lighting' in Elmsford, NY (15 Ci in March 1989), Model 710-A, S/N A60. The sign was mounted in the east stairwell of the 4th floor of the University Library, and was present during the quarterly inventory July 31, 2006. During the October inventory, and while the building was being remodeled, the sign was missing. The University staff investigated, but were unable to determine the disposition of the sign. The wall where the sign was mounted was removed by a contractor during the remodeling. The RSO discussed the situation with the Construction Manager and the University's Project Management Staff to avert such occurrences during future remodeling activities. The University will notify RHB if the sign is located. The most likely scenario is that this sign was disposed with other construction debris. 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.
