Nuclear chemistry

Nuclear chemistry is a subfield of chemistry dealing with radioactivity,
nuclear processes and nuclear properties. It may be divided into the
following categories:

   * Radiochemistry deals with the use of radioactivity to study ordinary
     chemical reactions
   * The application of techniques from chemistry to study nuclear reactions
     such as fission and fusion — see also nuclear physics.
   * Isotopic chemistry deals with the effect of nuclear mass on chemical
     reactions and the properties of compounds
