Tritium is an isotope of hydrogen. The nucleus of tritium contains one proton and two neutrons, whereas a hydrogen nucleus consists of just one proton. It's atomic weight is 3.
It is radioactive (low level - average of 6 keV beta emmitter) and has a half life of 12.3 years. The low energy beta radiatoin from tritium can not penetrate human skin, so tritium is only dangerous if consumed in large quantities.
Tritium occurs naturally due to cosmic rays interacting with deuterium in the atmosphere. It is produced in nuclear reactors by exposing Li6 to a neutron source.
Tritium figures prominately in studies of nuclear reactions, especially nuclear fusion due to it's favorable reaction cross section and high energy yield. Please explain further.
Small amounts are used with phosphors for self illuminating devices, especially watches and exit signs.
