- 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

- High doses can kill living cells so ca n be used to treat cancer
- Part of the electromagnetic spectrum

- Short wave length- about the width of an atom
- Physics X-rays p3
- 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
- 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
