Comparison of radioactive properties of uranium isotopes
The main isotopes of uranium contained in this table have extremely long lifetimes with the exception of uranium 232. All are alpha emitters of 4 to 5 MeV of energy. The left columns of the table show however the presence of a low energy gamma radiation and rare decays beta. Specific activities (activities reduced to 1 gram) are inversely proportional to half-lives.
