The exit sign was last inventoried in October 2021 and was noticed to be missing in April 2022. After extensive investigation/searching, the licensee considers the sign lost. The Exit sign in question is an Isolite H-3 Exit sign, model 880-126R10BA, S/N H138883, originally containing 7.59 Ci of H-3. Rutgers will forward a written report within 30 days concerning the loss and their investigation. 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.
