Event Description	The following summary was received from the Colorado Department of Public Health and Environment via email: On June 6, 2022, the Colorado Department of Public Health and Environment reported one model 2040 exit sign containing an unknown amount of tritium lost by the licensee. The incident occurred between 2009-2010. CO incident no.: CO220022 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.
