Beta Particles 2
Beta Particles 2 : Nuclear Energy and Nuclear Disasters. (Animation) (Image)?electrons?ejected from the?nucleus?of a decaying atom. Although they can be stopped by a thin sheet of aluminum, beta particles 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 orinhaled.?See also?alpha particle,?gamma rays,?neutron,?x-ray
