Tritium half-life t
Webt1/2 is the half-life τ is the mean lifetime λ is the decay constant If an archaeologist found a fossil sample that contained 25% carbon-14 in comparison to a living sample, the time of the fossil sample's death could be determined by rearranging equation 1, since Nt, N0, and t1/2 are known. This means that the fossil is 11,460 years old.

WebTritium December 2012 Tritium is a radioactive form, or “isotope”, of hydrogen. It has two neutrons where regular hydrogen does not have any, which makes tritium unstable and … WebTritium is the only radioactive isotope of hydrogen and like hydrogen it reacts with oxygen to form water. The transformation of tritium to tritiated water is a complex and slow process. Tritium is a colorless, odorless gas with a half-life of 12.3 years. Tritiated water moves through the environment like ordinary water. how are people exposed ...
