Ionizing Power of alpha and beta particles

Which has greater ionization power alpha or beta?


(Question received via speak pipe – a facility for the visitors to ask questions orally, if you have a mic)




Alpha particles have greater ionization power as they have two units of positive charge and 4 units of mass, whereas beta has only one unit of negative charge and negligible mass as compared to alpha.
