  • Types of Radiation
    • beta
      • ?
      • high speed - electron from the nucleus
      • CHARGE = -1
      • MASS = negligible
      • IONISATION ABILITY
        • medium (less than alpha because smaller)
      • PENETRATION
        • medium - few mm's of metal
    • alpha
      • ?
      • 2 protons, 2 neutrons
        • helium nucleus
      • MASS = 4
      • CHARGE = +2
      • IONISATION ABILITY
        • HUGE & knocks bits off things (DAMAGING)
      • PENETRATION
        • V.LOW (loses energy quickly colliding with e.g. air
    • gamma
      • ?
      • IONISATION ABILITY
        • small
      • PENETRATION
        • high (metres of concrete)
      • electromagnetic wave
        • NOT a particle
