Precautions while using X Rays
It is a test used to look at the bones and internal organs of the body. It is done by exposing the body to a brief amount of electromagneticradiation and then producing an image over the film. X rays used for medical purposes are about one order of magnitude shorter in wavelength. Diagnostic rays are designated for tissue penetration and are carefully filtered to avoid X ray damage to the skin caused by the longer, more readily absorbed wavelengths.
