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 … Skatīt vairāk 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 another isotope of … Skatīt vairāk 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 … Skatīt vairāk 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 … Skatīt vairāk 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, … Skatīt vairāk Lithium Tritium is most often produced in nuclear reactors by neutron activation of lithium-6. The release and diffusion of tritium and helium produced … Skatīt vairāk 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 Skatīt vairāk Biological radiometric assays Tritium has been used for biological radiometric assays, in a process akin to radiocarbon dating. … Skatīt vairāk TīmeklisThe glow comes from a phosphorus coating on the inside of the tube in which the tritium is trapped. The phosphor is excited by free electrons released by the tritium's decay and glows because of that. I'm not sure how that technology relates to a compass from the 1950's. UncleRon, 7 years ago. I agree on the date.

Hydrogen (1H) has three naturally occurring isotopes, sometimes denoted H , H , and H . H and H are stable, while H has a half-life of 12.32(2) years. Heavier isotopes also exist, all of which are synthetic and have a half-life of less than one zeptosecond (10 s). Of these, H is the least stable, while H is the most. Hydrogen is the only element whose isotopes have different names that remai…
