Beta Particle Definition: An electron or positron. The term is generally applied to an electron or positron emitted in radioactive beta decay.
Beta particles are electrons emitted from an atom. In air, beta particles can travel a few hundred times farther than alpha particlesâup to six feet (two meters) or more for the beta particles with higher energies. For the common low-energy beta emitters used in laboratories, light clothing or a few centimeters of air can stop the beta radiation.
