Half life of deuterium

WebMar 24, 2024 · Tritium is a radioactive species having a half-life of 12.32 years; it occurs in natural water with an abundance of 10-18 of that of natural hydrogen. Tritium was … WebTritium is a radioactive isotope that decays relatively quickly (it has a 12-year half-life) and is rare in nature. Exposing the element lithium to energetic neutrons can generate tritium. Scientists are researching ideas on how to breed tritium in fusion reactors at the required rate to make future power plants tritium self-sufficient.
