WebTritium activities are commonly described in terms of tritium units (TU), where 1 TU = 1 atom of tritium per 10 18 atoms of hydrogen or 1 TU = 7.19 DPML −1 of water = 0.118 Bq L −1 of water. The natural activities in precipitation vary from about 25 TU at high latitudes to about 4 TU in the equatorial zone ( Geyh and Schleicher, 1990 ). Tritium (from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or H) is a rare and radioactive isotope of hydrogen with a half-life of about 12 years. The nucleus of tritium (t, sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen … See more Tritium was first detected in 1934 by Ernest Rutherford, Mark Oliphant and Paul Harteck after bombarding deuterium with deuterons (a proton and neutron, comprising a deuterium nucleus). Deuterium is … See more While tritium has several different experimentally determined values of its half-life, the National Institute of Standards and Technology lists … See more Tritium has an atomic mass of 3.01604928 u. Diatomic tritium (T2 or H2) is a gas at standard temperature and pressure. Combined with oxygen, it forms a liquid called See more Tritium has leaked from 48 of 65 nuclear sites in the US. In one case, leaking water contained 7.5 microcuries (280 kBq) of tritium per liter, … See more Lithium Tritium is most often produced in nuclear reactors by neutron activation of lithium-6. The release and diffusion of tritium and helium produced by … See more Tritium is an isotope of hydrogen, which allows it to readily bind to hydroxyl radicals, forming tritiated water (HTO), and to carbon atoms. Since … See more Biological radiometric assays Tritium has been used for biological radiometric assays, in a process akin to radiocarbon dating. For example, in one paper, [ H] See more
