Tritium - Wikipedia
Tritium decays into helium-3 by beta-minus decay as shown in this nuclear equation: releasing 18.6 keV of energy in the process. The electron 's kinetic energy varies, with an average of 5.7 keV, while the remaining energy is carried off by the nearly undetectable electron antineutrino.
Tritium’s concentration in the environment is ever-changing, increasing with natural processes and human activities and decreasing through radioactive decay. Over time, tritium released into the environment becomes distributed by the same process that transports water (referred to as the hydrological cycle or water cycle).

2024年12月7日 · 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
Tritium decays with a half-life of 12.32 years. The specific activity of tritium is approximately 9,619 Ci/gram, and/or 1.040×104 grams per Ci.
Unveiling The Lifespan: How Long Does Tritium Endure?
2024年10月16日 · Tritium, a radioactive isotope of hydrogen, decays with a half-life of 12.3 years, meaning it takes 12.3 years for half of a sample to decay. The decay constant, λ, which governs the rate of decay, is related to the half-life T by λ = ln(2)/T.
Tritium decays by emitting a beta particle and turning into helium. The release of radiation during this decay process causes concern about the safety of tritium and all other radioactive substances. The radiation from the decay of tritium is in the form of beta particles which are of very low energy.
