Plutonium decays with a half-life of 24000 years.If plutonium is stored for 72000 years.What fraction of it remains?
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.
