  • Radiation
    • Types of radiation
      • Beta
        • Penetrate air and paper
        • Moderatly ionising
        • Basically an electron
      • Gamma
        • Moves really quickly
        • Most penetrating
        • High levels stoppped by lead
      • Alpha
        • Highly ionsing
        • Slow moving
        • Two protons and two neutrons
    • Background radiation
      • Rocks underground
      • Untitled
      • Space --> rays from sun
      • Artifical sources --> nuclear waste and nulcear activity
    • Uses of radiation
      • Killing cancerous cells - gamma
      • Alpha - Smoke detectors
      • Sterling food and instruments
      • Medical Tracers
    • Radioactivity safety
      • Never look it directly in the eye
      • Hold with tongs
      • Store in a lead box
      • Minimise exposure
      • Wear lead clothing and stand behind lead screens
        • lead absorbs all rays
