The beta particle is a form of ionizing radiation related to other common forms of radiation, alpha particles and gamma rays.The beta particle is a high-speed electron or positron released from a degenerating radioactive nucleus.Being medium-energy and low mass, beta particles are one of the least damaging forms of radiation, but still a very significant health concern.he beta particle is a high-speed electron or positron released from a degenerating radioactive nucleus.

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.
