Radiation
- Beta
  - Fast moving electron
    - Relative mass: 1/1800
    - Relative charge: -1
  - Weak ionising effect
  - Deflected in magnetic and electric fields by a greater amount and in a opposite direction to alpha particles
  - more penetrating than alpha
    - Absorbed by a few mm of aluminium
  - - Fast moving electron
      - Relative mass: 1/1800
      - Relative charge: -1
- Alpha
  - Deflected by electric and magnetic fields
  - Not very strong penetrating effect
    - Absorbed by a few cm of air or a few sheets of paper
  - Strong Ionising effect
  - - Helium nucleus
      - Relative charge: +2
      - Relative mass: 4
