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).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 (net heat consuming) reaction, consuming 2.466 Me V.This was discovered when the 1954 Castle Bravo nuclear test produced an unexpectedly high yield.This identified that the March 2016 holding of tritium on-site was 760 TBq (equivalent to 2.1 g of tritium or 14 m L of tritiated water) in a total of 860000 m of stored water.

In comparison, the fusion of deuterium with tritium releases about 17.6 Me V of energy.Tritium is also produced in heavy water-moderated reactors whenever a deuterium nucleus captures a neutron.
