What is Tritium?
From the EPA's (Environmental Protection Agency) website:

"Tritium (chemical symbol H-3) is a radioactive isotope of the element hydrogen (chemical symbol H). Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules. Tritium is also produced as a byproduct in reactors producing electricity, and in special production reactors, where the isotope lithium-6 is bombarded to produce tritium. Tritium occurs naturally in the environment in very low concentrations. Most tritium in the environment is in the form of tritiated water, which easily disburses in the atmosphere, water bodies, soil, and rock. People are exposed to small amounts of tritium every day, since it is widely dispersed in the environment and in the food chain.

Tritium is produced commercially in reactors. It is used in various self-luminescent devices, such as exit signs in buildings, aircraft dials, gauges, luminous paints, and wristwatches. Tritium is also used in life science research, and in studies investigating the safety of potential new drugs.

Tritium is one of the least dangerous radionuclides because it emits very weak radiation and leaves the body relatively quickly."

Because Tritium is safe it has replaced radium (which has been banned for use in the United States as a hazardous substance) for a luminescent source in watches and gauges.
