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.

Page 4. Beta decay is a radioactive process in which an electron is emitted from the nucleus of a radioactive atom, along with an unusual particle called an antineutrino.The neutrino is an almost massless particle that carries away some of the energy from the decay process.ecause this electron is from the nucleus of the atom, it is called a beta particle to distinguish it from the electrons which orbit the atom. Like alpha decay, beta decay occurs in isotopes which are neutron rich (i.e. have a lot more neutrons in their nucleus than they do protons).
