X-rays are used for: 

  • imaging bones
  • medical treatments
  • killing cancer cells
  • radiotherapy


  • cheap and easy
  • quick
  • good bone resolution
  • easily interpreted


  • cause cancer
  • ionising (leads to chemical change in cells)
  • poor soft tissue resolution
  • contrast media can be unpleasant and hazardous (contrast medium includes barium meals and injection of iodine)

How to improve the quality of x-rays:

  • Filteration - x-rays passed through a filter which absorbs low frequency rays but
