Title	Lost Exit Sign
Event Description	The following is a synopsis of information provided by the Colorado Department of Public Health and Environment via email: On 6/23/23, the licensee discovered that a tritium exit sign was lost. The exit sign was an Isolite Corporation Model 2000 containing 7.62 Ci of tritium (H-3). This is being reported under Colorado Regulations Section 4.51.1.1 (10 CFR 20.2202(a)(1)(i)). Event Report ID No.: CO230017 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.
