These companies use the tritium to make self-luminous exit signs. TAP believes that the marketing of radioactive waste in these products should be prohibited. Safer, more effective and more energy efficient alternatives are available.

Besides being hazardous during manufacture and disposal, tritium lights and products containing them are hazardous during use. The tritium contained in a single exit sign, if fully oxidized and inhaled would constitute a lethal dose of radiation. Incidents have occurred in the United States where lights have been accidentally or intentionally broken, thus requiring expensive emergency measures including evacuations and decontamination operations.

This and other problems are described in the TAP fact sheet “Problems with tritium exit signs” available in PDF format for download in the documents section of this website.
