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. Being medium-energy and low mass, beta particles are one of the least damaging forms of radiation, but still a very significant health concern.
After a radioactive nucleus has emitted a beta particle, the mass number stays the same and the atomic number goes up by 1. A neutron in the nucleus has changed into a proton plus an electron. The proton stays inside the nucleus but the electron is emitted as a beta particle.ome nuclei can decay by emitting either an alpha particle or a beta particle. An example is bismuth where 1/3 of the atoms emit an alpha particle and 2/3 of the atoms emit a beta particle. You can work out which particle is emitted by balancing the equation.
