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 4,500 ± 8 days (12.32 ± 0.02 years). It … 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 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, which is 375 times the current EPA limit for … 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 tritium is a low energy 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] retinyl acetate was traced through the body of Sprague-Dawley rats. Self-powered lighting See more El tritio es un isótopo natural (y también producido de forma artificial) del hidrógeno; es radiactivo. Su símbolo es ³H. Su núcleo consta de un protón y dos neutrones. Tiene un periodo de semidesintegración de 12,3 años [(4500 ± 8) días]. El tritio se produce por bombardeo con neutrones libres de blancos de litio, boro o nitrógeno. Su producto de desintegración es ³He
