  • They don't penetrate far into materials but are stopped quickly
  • They are highly ionising
  • They're positively charged, so they are deflected by electric and magnetic fields

Beta particles are electrons:

  • A beta particle is an electron that has been emitted from the nucleus of an atom when a nuetron turns into a proton and an electron, so…
