WebDecay of Tritium. Tritium is a radioactive isotope, but it emits a very weak form of radiation, a low-energy beta particle similar to an electron. It is a pure beta emitter (i.e., beta emitter without accompanying gamma radiation).The electron’s kinetic energy varies, with an average of 5.7 keV, while the nearly undetectable electron antineutrino carries off the … In nuclear physics, beta decay (β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide. For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or, conversely a proton is converted into a neutron by the emission of a positron with a neutrino in so-called positron emission. Neither the …

"WebBeta-minus decay occurs in nuclei with an excess of neutrons, while beta-plus decay takes place in neutron-deficit nuclei. A lot of natural background radiation on Earth is due to fission or alpha-decay of heavy radioactive elements. The remains of fission or alpha-decay are neutron-rich nuclei, so beta-minus decay is more common on Earth. " - Fission beta decay
