noun, plural: X-radiations

A form of electromagnetic radiation emitting X-rays


The electromagnetic radiation is a form of radiation released in the form of electromagnetic waves. The distance between successive crests is called the wavelength. The shorter the wavelength, the greater is the amount of energy. There are many forms of electromagnetic radiation and one of which is X-radiation.

X-radiation is the emission of X-rays that are characterized generally by its wavelength ranging from 0.01 to 10 nm, and corresponding to frequencies ranging from 30 petahertz to 30 exahertz, and with energies in the range of 100 eV to 100 keV. In terms of wavelengths, X-rays are shorter than UV rays and typically longer than gamma rays. The name x was coined by the German physicist, Wilhelm Röntgen. In 1895, he was the first to describe X-rays using x to denote an unknown quantity.

X-rays are currently used for medical and diagnostic purposes. Radiography, an imaging technique used to view internal structures, employ X-radiation. X-rays are used to create images of the internal structures to detect pathologies of the skeletal system and soft tissues since X-rays are able to pass through them and can expose photographic films.
