Title	Lost Tritium Exit Signs
Event Description	The following is a summary of a phone call with the licensee: After performing an inventory of Tritium exit signs in April of this year, a Senior Health Physicist inquired about the location of two specific missing signs. The Senior Health Physicist found that the building had been under renovation in 2018 and a contractor likely removed the two exit signs in November, 2018. The licensee is currently waiting on information from the contractor regarding the exit signs. The licensee will be notifying NRC Region III. 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.
