AB KEY  POINTSElements  are  defined  by  the  number  of  protons  in  the  nucleus.  Nuclides  are  defined  by  the  number  of  protons  and  the  number  of  neutrons.The  ratio  of  protons  to  neutrons  determines  the  stability  of  a  nucleus.Unstable  nuclei  decay  to  a  more  stable  state  through  several  different  mechanisms:  α  decay,  β−  decay,  β+  (positron)  decay,  electron  capture,  and  isomeric  transition.The  rate  at  which  unstable  nuclei  decay  can  be  described  by  the  decay  constant.  It  is  often  more  convenient  to  describe  the  rate  of  decay  by  the  half-life.The  interaction  of  radiation  with  matter  is  dependent  on  the  energy  and  type  of  the  radiation,  as  well  as  the  atomic  number  (Z  number)  of  the  matter.Attenuation  is  the  loss  of  radiation  as  it  passes  through  matter  and  is  absorbed  or  deflected.
