Title	Lost Exit Signs
Event Description	The following information was provided by the California Department of Public Health, Radiologic Health Branch via email: Isolite Corporation notified the California State Warning Center of the loss of a container containing eight tritium exit signs with a total activity of 60.8 curies of tritium (H-3). Fifty-one containers of tritium signs were to be delivered by [common carrier]. Only 50 containers of tritium exit signs were delivered, leaving one container containing the eight exit signs missing. [The common carrier] is currently conducting a search to determine the status of the missing container of exit signs. Since this exceeds the amount of H-3 by greater than 1000 times the value in Appendix C of Part 20, it constitutes a less than or equal to 24-hour reportable event. 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.
