X-RAY
WHAT IS X-RAY?
X-ray radiation, or, much less commonly, X-radiation, is a penetrating form of high- energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 nanometers to 10 picometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 124 keV to 145 eV, respectively. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as R?ntgen radiation, after the German scientist Wilhelm Conrad R?ntgen, who discovered it on November 8, 1895. He named it X-radiation to signify an unknown type of radiation.[2] Spellings of X-ray(s) in English include the variants x-ray(s), xray(s), and X ray(s).
TYPES OF X-RAY:

WORKING OF X-RAY:
An X-ray sends beams of radiation through your body. Radiation beams are invisible, and you can’t feel them. The beams pass through your body and create an image on an X-ray detector nearby. As the beams go through your body, bones, soft tissues and other structures absorb radiation in different ways. Solid or dense objects (such as bones) absorb radiation easily, so they appear bright white on the image. Soft tissues don’t absorb radiation as easily, so they appear in shades of grey on the X-ray.
SIDE EFFECTS:
While X-rays are linked to a slightly increased risk of cancer, there is an extremely low risk Trusted Source of short-term side effects. Exposure to high radiation levels can have a range of effects, such as vomiting, bleeding, fainting, hair loss, and the loss of skin and hair. However, X-rays provide such a low dose of radiation that they are not believed to cause any immediate health problems.
