from a previous answer:
An isotope in the eye.Tritium (symbol T or 3H) is a radioactive isotope of hydrogen. The nucleus of tritium (sometimes called triton) contains 1 proton and two neutrons, whereas the nucleus of protium (the most abundant hydrogen isotope) contains no neutrons. Its atomic weight is 3.0160492. It is a gas (T2 or 3H2) at standard temperature and pressure. Tritium combines with oxygen to form a liquid called tritiated water T2O or partially tritiated THO.
Tritium is radioactive with a half-life of 12.32 years. It decays into helium-3 by the reaction .
