Tritium (/ ˈ t r ɪ t i ə m / or / ˈ t r ɪ ʃ i ə m /, from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or 3 H) is a rare and radioactive isotope of hydrogen.The nucleus of tritium (sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (protium) contains just one proton, and that of hydrogen-2 ...

Tritium is a radioactive form, or “isotope”, of hydrogen. It has two neutrons where regular hydrogen does not have any, which makes tritium unstable and therefore radioactive. It is produced naturally from interactions of cosmic rays with gases in the upper

Tritium is produced naturally in the upper atmosphere when cosmic rays strike nitrogen molecules in the air. Tritium is also produced during nuclear weapons explosions, and as a byproduct in nuclear reactors. Although tritium can be a gas, its most common form is in water because radioactive tritium reacts with oxygen to form water.

Tritium is the only radioactive isotope1 of hydrogen and it is commonly represented by the chemical symbol H-3, 3H, or simply T. Being radioactive causes tritium to undergo a process of radioactive decay. During this decay process, the tritium atom transforms into a nonradioactive helium atom and, in the process, emits a form of ionizing radiation known as a beta particle. The emission of this beta particle during the decay process is what makes tritium a potentially hazardous material.

Tritium can exist as an odorless and colorless gas, like ordinary hydrogen, but the element is mainly found in liquid form as part of tritiated water or T 2 O, a form of heavy water.

Tritium is the radioactive isotope of hydrogen with a half life of 12.3 years. It decays through the emission of a beta particle with a maximum energy of 18.7 keV and an average energy of 5.7 keV (Okada, 1993). The mean free path of tritium’s decay beta particle in tissue is about 0.6 µm, the diameter of a human chromosome.

The model for dose from tritium gas, HT, does account for a small portion of the tritium intake (0.01 percent) being converted to tritiated water in the body, and this small amount of HTO does dominate the committed dose. The effective dose to the whole body as a result of an intake of I Bq of HT is given (as per ICRP 68) as

Radioluminescent 1.8- curie (67 GBq) 6-by-0.2-inch (152.4 mm × 5.1 mm) tritium vials are tritium gas-filled, thin glass vials with inner surfaces coated with a phosphor. Tritium radioluminescence is the use of gaseous tritium, a radioactive isotope of hydrogen, to create visible light.

Tritium is a naturally found Hydrogen atom with an atomic weight of 3, so its symbol is H3. In watches the gas is hermetically sealed inside glass tubes (vials) coated with phosphorescent paint, together this creates a chemical reaction producing colourful glowing light.
