Unlimited-Tritium, as a form of Hydrogen, is found naturally in

air and water. Most hydrogen is made up of one proton, and an

orbital electron, but tritium has two extra neutrons in the

nucleus. In nature, it is produced by cosmic rays in two source

terms: 14N + 1n ---> 3H + 12Cand2H + 2H ---> 3H + 1

Tritium is not normally considered to be naturally occurring.

The amounts produced by cosmic rays are trace. To produce it in

meaningful amounts you need either a nuclear reactor or bomb.

Besides it decays rapidly, in 61.3 years any present now is

effectively gone.
