Title	Lost Tritium Exit Sign
Event Description	The following information was provided by the California Department of Public Health via email: On Monday, March 17, 2025, the California State University - Long Beach alternate radiation safety officer reported the loss of one tritium exit sign from their campus' Carpenter Performing Art Center. This exit sign was an Isolite tritium exit sign, made on April 5th, 2015, Model 2000, S/N H50630, with an initial tritium activity of 0.281 TBq (7.6 Ci). The exit sign was officially declared lost on March 14, 2025, after a thorough search by campus environmental health and safety personnel could not locate the exit sign. A contamination survey of the exit sign's designated location did not show the presence of tritium contamination. The licensee will continue to look for the exit sign and provide additional information when available. Corrective actions included refresher training, increased physical inventories of all campus tritium exit signs, and review of methods of securing of exit signs to mounting surfaces. California 5010 number: 031725 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.
