WebJul 30, 2016 · 1. An alpha decay is a two body, a beta decay is a three body decay. We have energy and momentum conservation for both, i.e. there are two equations to satisfy and in … Webtype and energy of the radiation. Three beta-emit-ting radioisotopes have been considered here. The classical radioiodine, 131I, is a beta emitter, but the beta decay is immediately followed by a gamma decay of the excited daughter nucleus, meaning that one has to shield as much against gamma radiation as against beta radiation.
