In nuclear physics, beta decay (Î²-decay) is a type of radioactive decay in which a beta ray, and a respective neutrino are emitted from an atomic nucleus.
A high-speed electron or positron, especially one emitted from the nucleus of an atom in radioactive decay. an electron emitted from the nucleus of an atom during radioactive decay of the atom. Beta particles have a range of 10 m in air and 1 mm in soft tissue. Also called beta ray. An ionising electron or positron which is emitted from decaying radioactive nuclei during beta decay or beta emission.
