A Guide to SI Units in Radiation Protection: Operational Topic

Self-luminous signs are generally licensed consumer products used to identifying exits, handicap accessibility areas, parking lots, no smoking areas, life boat locations, and emergency stair locations. While purchasers of these signs are exempt from the requirement of applying for a specific license, they are not exempt from all other requirements concerning radioactive material. And they might not be exempt from the liability that can result from lost or damaged signs and improper disposal. A review of the potential for contamination from these signs is presented along with suggestions for handling a contaminating event involving a damaged sign.
