Beta Particle Definition: An electron or positron. The term is generally applied to an electron or positron emitted in radioactive beta decay.
See Alpha decay. Beta is a particle, a highly energetic electron or positron ejected by decay of a neutron or proton in a radioactive isotope atom. See Beta decay. Gamma radiation comprises highly energetic photons above the x-ray energy range that may arise in nuclear decay or reach earth from space.. In one example, Cobalt-60 decays to release a beta particle followed by gamma radiation from the resulting nickel 60.
