1.1 High frequency and very short wave length
1.1.1 Their wavelength is about the same size as the diameter of an atom
2 Properties
2.1 Affect a photographic film in the same way as light
2.2 Are absorbed by metal and bone
2.3 Are transmitted by healthy tissue
2.3.1 Can be filled with contrast medium that absorbs X-rays so that they can be seen on an X-ray image
2.4 Can be used to treat cancerous tumours at or near the body surface
3 Are used to form images of bones on photographic film
3.1 Check for fractures and dental problems
4 Charge-coupled devices (CCDs)
4.1 Used to form electronic images of X-rays
5 CT scanners
5.1 Use X-rays to produce digital images of a cross-section through the body
6 Risks
6.1 Cn cause ionisation
6.2 Can damage living tissue when they pass through it
