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.

Alpha and Beta particles are actually physical particles of matter. The Alpha is two protons and two neutrons, and consequently is relatively very heavy and slow and carries a double positive charge.. A Beta is simply an electron and has a negative charge. The Beta may be moving from very slow to very fast, and the speed is an indication of it's energy level. Gamma Radiation is a true electromagnetic energy, and moves at or near the speed of light. Alphas can barely penetrate anything, not even a piece of paper. Betas do a bit better but still can only penetrate a thin piece of aluminum. Gammas on the other hand can penetrate inches of lead and feet of most other things.
