Alpha rays
(gcide) | Alpha rays \Alpha rays\ (Physics & Chem.)
Rays of relatively low penetrating power emitted by radium
and other radioactive substances, and shown to consist of
positively charged alpha particles (helium nuclei) having
enormous velocities but small masses. They are slightly
deflected by a strong magnetic or electric field. Compare
beta ray and gamma ray. Because the rays penetrate only a
small distance in dense matter such as living tissue, small
pellets of radioactive substances emitting alpha rays have
been used to cause local destruction of tissue, as in cancer
therapy.
