  • Physics X-rays p3
    • High doses can kill living cells so ca n be used to treat cancer
      • the rays re focused on the tumour, Then the beam is rotated round the patient with the tumour at the centre
        • This reduces the exposure to normal cells so minimises the chance of damaging the rest of the body
  • Part of the electromagnetic spectrum

    • Short wave length- about the width of an atom
  • It affects photographic film in the same way as light
    • Absorbede by bones and metal so x-rays won't reach the film if these are in the way
      • It affects photographic film in the same way as light
      • CT scans
        • An x-ray tube which can rotate to see all angles- it is connected to a CCD which converts it to light
        • It distinguishes between types of tissue and forms a 3D image
        • People who work with it for a living must wear lead aprons and a film badge which says if the person has been near too much radiation
        • CT scans  give a large dose of radiation, however it is a 3D image  though it is expensive

      awesome!!!!! thank youuu!!!!

      Miss KHP

      Easy links to follow. Great way to help people understand CT scans and X-rays. Nice use of colours.
