Helium 3 half life
WebTritium is a radioactive isotope of hydrogen that decays beta with a 12.3-year half-life to He3 [ 17 ]. Tritium is an essential component for the construction of nuclear weapons but its production has been significantly reduced after the end of the Cold War. WebTritium (symbool T of 3 H) is een isotoop van waterstof met in de atoomkern een proton en twee neutronen, in plaats van alleen maar een proton (bij protium).De atoommassa …
