Uses of X-rays
1. Medicine – X-ray photos called radiographs are used as diagnostic tools for various diseases. They are also used to treat cancer in radiotherapy.
2. Industry – they are used to photograph and reveal hidden flaws i.e. cracks in metal casting and welded joints.
3. Science – since the spacing of atomic arrangement causes diffraction of x-rays then their structure can be studied through a process called X-ray
crystallography.
4. Security – used in military and airport installations to detect dangerous metallic objects i.e. guns, explosives, grenades etc.
