Ionising ability of alpha particles
WebAlpha decay is a type of radioactive disintegration in which some unstable atomic nuclei dissipate excess energy by spontaneously ejecting an alpha particle. The resulting daughter nuclei have a mass number reduced by four and an atomic number that’s reduced by two from its parent nuclei. An alpha particle is just like the nucleus of a helium ...
