  • Types of radiation
    • Gamma
      • least ionising
      • most dangerous to the body
      • travels at the speed of light
      • high energy electromagnetic wave
      • no mass
      • only stopped by thick lead or very thick concrete
    • Beta
      • moderately ionising
      • negative charge
      • tiny(negligible) mass
      • an electron
      • stopped by aluminium or paper
    • Alpha
      • least penetrating
      • slowest moving
      • most ionisng
      • stopped by skin or paper
      • +2 positive charge
      • relative mass of 4
