WebTritium, also referred to as hydrogen-3, is a radioactive isotope of hydrogen which is incredibly uncommon. The symbol of Tritium is T or 3H. Unlike ordinary hydrogen, which only has one neutron, tritium has two neutrons, making it unstable and radioactive.Cosmic rays striking airborne nitrogen molecules in the high atmosphere naturally generate tritium.
