  • P3;
  • Radiation;
    • P3;
  • def; a type of energy that  spreads out from a source.
    • Radiation;
    • It can be in the form of electromagnetic waves (i.e - light or gamma)
      • or
      • def; a type of energy that  spreads out from a source.
      • Intensity of the radiation decreases with distance
      • and depending on the density of the object its traveling through (i.e water)
        • Intensity of the radiation decreases with distance
      • Uses in Medicine;
        • diagnosis (identifying a problem) or therapy (treating the problem)
          • diagnosis - CAT Scans, endoscopes(non-ionising) and ultrasound.
            • therapy -  lasers for eye and skin problems, ionising  for cancer and ultra sound to help healing.
