why are alpha and beta radiation referred to as particles while gamma radiation is referred to as rays?

  • Science radioactivity -

    Alpha and beta particles really are particles in that sense of the word. The alpha particle is a helium nucleus and a beta particle is an electron. A gamma is a ray; i.e., an electromagnetic wave much like a radio or TV wave (but a much shorter wavelength and much higher energy).
