nuclear

• Radiation is random and spontaneous
• This is beta-minus decay

  
• This is beta-plus decay

  
• The force holding protons together in an atom is called the strong nuclear force and attracts up to 3 fm and repels under 0.5 fm
• Hadrons, such as protons, neutrons and mesons experience both strong and weak nuclear forces
• Leptons, such as electrons, muons and neutrinos are only affected by weak nuclear forces and not strong nuclear forces
• This is beta minus decay

  
• This is beta plus decay
