Can paper stop alpha particles
WebJan 20, 2005 · Alpha rays: These particles aren't really "rays," they are bare helium nuclei (helium atoms that have lost their electrons hence becoming positively charged) traveling through space. They are complosed of two neutrons and two protons and have a charge of +2. Beta rays: Like alpha rays, these aren't really "rays" either. They are positrons.
