| Title | Lost Tritum Exit Sign |
| Event Description | The following report was received from the Virginia Radioactive Materials Program via email:
On April 16, 2021, at 1605 EDT, the Virginia Radioactive Materials Program received a report from the licensee that a 6.2 Curie [tritium] exit sign (Shield Source Inc., S/N: 11-36361) was lost. The licensee was performing an inventory of [tritium] exit signs on April 15, 2021. The licensee's report indicated that the exit sign was not found at the location where it was last inventoried in 2020 by the Radiation Safety Department. The licensee contacted their Facilities Management Department, asked them about construction being performed at the location, and if the whereabouts of the sign was known. On April 16, 2021 after another search and email correspondence with Facilities Management, the licensee determined that the [tritium] exit sign was lost and was likely discarded with construction trash. The licensee submitted a corrective action plan in their report stipulating that Facilities Management will provide a point of contact with whom the Radiation Safety Program will work with regarding [tritium] exit signs to: (1) ensure they are not removed without proper notification, and (2) to notify the Radiation Safety Program of the installation of any new [tritium] exit signs placed within the University of Virginia. Virginia Report ID No.: VA210002 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.
