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 is an electron. A gamma ray is a high-frequency electromagnetic photon. The alpha particle is the least penetrating, because it is large and has the highest charge; due to its high charge, the particle is strongly repelled via electrostatic repulsion. A beta particle is more penetrating than an alpha particle, due to its smaller size and lower charge, but less penetrating than a gamma particle.
