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.

A beta particle comes from the nucleus of an atom! It has a charge of -1 and very little mass (only 1 Ã· 1840 as big as a proton). The e shows that the particle is an electron. A beta particle is given a mass number of zero because the mass is very small compared to a proton or a neutron.. A beta particle has a negative charge because it is an electron. 2. A beta particle has less mass than an alpha particle but more mass than a gamma ray. See the three types of radioactivity.
