X-rays produce an image by sending a beam of rays (very high energy electromagnetic radiation) through the body.  Different tissues in the body have different densities and absorb and deflect the X-rays differently.  A camera records on photographic film the varying levels of X-rays that have passed through the body.

Some reasons why X-rays are used include...

• determining if a bone is broken,
• seeing whether an internal organ is infected and
• looking for cancer.
