There are three type of radiation, Alpha, Beta and Gamma.
Alpha doesn't travel far from the source and is a weak type, can't pass through 1 piece of paper or the first layers of skin.
Beta, lasts longer than Alpha and can pass though multiple layers of skin.
Gamma is the worst. It's the type used in radiation therapy, Neutron is the last. Reference
