What is tritium lights?

Tritium lights are small, self-contained devices that use the radioactive gas tritium to produce a steady, low-intensity glow. The gas is stored within a sealed glass tube that is coated with a phosphorescent material that emits light when excited by the radioactive particles emitted by the tritium.

Tritium lights are commonly used as keychain fobs, small tactical flashlights, and watches. They are popular among outdoor enthusiasts and military personnel, as they provide a reliable source of light that is visible even in total darkness.

While tritium lights are generally considered safe, some precautions should be taken when handling them. The radioactive material is sealed within the glass tube, so there is very little risk of exposure. However, if a tritium light is broken or damaged, the gas can escape and pose a health hazard. It is also important to dispose of tritium lights properly, as they are considered radioactive waste and should not be thrown away in the trash.
