covers wavelengths from about 10–8 m (10 nm) down to 10–13 m
(10–4 nm) One common way to generate X-rays is to bombard a metal
target by high energy electrons X-rays are used as a diagnostic tool in
medicine and as a treatment for certain forms of cancer Because X-rays
damage or destroy living tissues and organisms, care must be taken to
avoid unnecessary or over exposure
