Thorium-231 emits a beta and a gamma
WebUranium and thorium are not stable. They break down in a process called radioactive decay. More than 99% of natural uranium exists in a form (isotope) called uranium-238 while more than 99% of natural thorium exists as thorium-232. These metals decay very slowly eventually to form lead. WebWhen it decays it emits a beta particle and a gamma ray, leaving behind a protactinium-234 atom. A protactinium-234 atom has 91 protons and 143 neutrons. It has a half-life of …
