Definition of «Beta particle»

Beta particle: An electron ejected from the nucleus of a decaying atom. Although beta particles can be stopped by a thin sheet of aluminum, they can penetrate the dead skin layer, potentially causing burns. They can pose a serious direct or external radiation threat and can be lethal depending on the amount received. They also pose a serious internal radiation threat if beta-emitting atoms are ingested or inhaled.
