Beta particles from tritium can penetrate only about 6.0 mm of air, and they are incapable of passing through the dead outermost layer of human skin.

The unusually low energy released in the tritium beta decay makes the decay (along with that of rhenium-187) appropriate for absolute neutrino mass measurements in the laboratory (the most recent experiment being KATRIN).

The name of this isotope is derived from Greek and it releases 18.6 ke V of energy in the process.

This is why brown dwarfs (so-called failed stars) cannot utilize ordinary hydrogen, but they do fuse the small minority of deuterium nuclei.This is possible with neutrons of any energy, and is an exothermic reaction yielding 4.8 Me V.In comparison, the fusion of deuterium with tritium releases about 17.6 Me V of energy.It can be produced by irradiating lithium metal or lithium-bearing ceramic pebbles in a nuclear reactor.Tritium is used as a radioactive tracer, in radioluminescent light sources for watches and instruments, and, along with deuterium, as a fuel for nuclear fusion reactions with applications in energy generation and weapons.

For applications in proposed fusion energy reactors, such as ITER, pebbles consisting of lithium bearing ceramics including Li High-energy neutrons can also produce tritium from lithium-7 in an endothermic (a net heat consuming reaction) reaction, consuming 2.466 Me V.
