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 decays into helium-3 by beta decay as per this nuclear equation: 1H → 2He + e + ν e and it releases 18.6 keV of energy in the process. The … See more 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 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 … 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 tritiated water (T2O). Compared to hydrogen in its natural composition on … See more Biological radiometric assays Tritium has been used for biological radiometric assays, in a process akin to radiocarbon dating. … See more Lithium Tritium is most often produced in nuclear reactors by neutron activation of lithium-6. The release and … 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 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 WebJun 19, 2024 · It has a half-life of 12.3 y. After 12.3 y, half of the sample will have decayed from hydrogen-3 to helium-3 by emitting a beta particle, so that only 50.0 g of the original tritium remains. After another 12.3 y—making a total of 24.6 y—another half of the remaining tritium will have decayed, leaving 25.0 g of tritium.
