Tritium compasses are compasses that use tritium illumination. Tritium illumination is the use of gaseous tritium, a radioactive isotope of hydrogen, to create visible light. Tritium regularly emits electrons through beta decay, and when they interact with a phosphor material, fluorescent light is created, a process called radioluminescence. As tritium illumination requires no electrical energy, it found wide use in applications such as tritium compasses, emergency exit signs, and illumination of wristwatches. More recently, many applications using radioactive materials have been replaced with photoluminescent materials. These light sources are most often seen as "permanent" illumination in compasses intended for nighttime, or tactical use. Tritium compasses are favored by the military for critical applications where illumination of the glow-in-the-dark sort is desired but a power source may not be available. Tritium lighting is readily sold and used in US and is legal in most of Asia and Australia. While these devices contain a radioactive substance, it is currently believed that self-powered lighting does not pose a significant health concern. Tritium presents no external radiation threat when encapsulated in non-hydrogen-permeable containers. Direct, short-term exposure to small amounts of Tritium is relatively harmless. If a tritium tube should break, one should leave the area and allow the gas to diffuse into the air. Tritium exists naturally in the environment, but in very small quantities. Tritium compasses are also known as: hiking tools night compass, camping equipments travel compasses, military expedition radioactive compass, made in usa emergency navigation tool, compass store, official military nautical sighting, us government night compass, no battery glow in the dark, gaseous tritium compass, luminescent tritium beta compass, etc. Tritium compasses are commonly misspelled as tritum, tritim, compas, campass, glowe in the dark, commpass, etc.
