Tritium, (T, or 3H), the isotope of hydrogen with atomic weight of approximately 3. Its nucleus, consisting of one proton and two neutrons, has triple the mass of the nucleus of ordinary hydrogen. Tritium is a radioactive species having a half-life of 12.32 years; it occurs in natural water with an.
The awesome power of modern nuclear arsenals conceals a deep vulnerability. Sophisticated nuclear weapons are dependent upon tritium, a rare radioactive gas that decays inexorably by 5 per cent.
December 2013 Environmental Fate of Tritium in Soil and Vegetation 1. Introduction 1.1 Tritium in the environment Tritium is a radioactive isotope of hydrogen that emits low-energy beta radiation, which can be absorbed by paper, plastic, glass or metal. It can pose a health risk if it is ingested by drinking.
