==Description==<br />
''X-radiation'' (composed of '''X-rays''') is a [[form]] of [http://en.wikipedia.org/wiki/Electromagnetic_radiation electromagnetic radiation]. X-rays have a [[wavelength]] in the range of 10 to 0.01 [http://en.wikipedia.org/wiki/Nanometer nanometers], corresponding to [[frequencies]] in the range 30 petahertz to 30 exahertz (3 × 10/16 Hz to 3 × 10/19 Hz) and energies in the range 120 eV to 120 keV. They are shorter in wavelength than [http://en.wikipedia.org/wiki/UV UV] rays and longer than [http://en.wikipedia.org/wiki/Gamma_ray gamma rays]. In many languages, X-radiation is called ''Röntgen radiation'', after [http://en.wikipedia.org/wiki/Wilhelm_R%C3%B6ntgen Wilhelm Conrad Röntgen], who is generally credited as their discoverer, and who had named them X-rays to signify an [[unknown]] [[type]] of [[radiation]].<br />
<br />
X-rays from about 0.12 to 12 keV (10 to 0.10 nm wavelength) are classified as "soft" X-rays, and from about 12 to 120 keV (0.10 to 0.010 nm wavelength) as "hard" X-rays, due to their penetrating abilities.<br />
<br />
Hard X-rays can [[penetrate]] [[solid]] objects, and their largest use is to take images of the inside of objects in [[diagnostic]] [http://en.wikipedia.org/wiki/Radiography radiography] and [http://en.wikipedia.org/wiki/X-ray_crystallography crystallography]. As a result, the term X-ray is [http://en.wikipedia.org/wiki/Metonomy metonymically] used to refer to a radiographic image produced using this [[method]], in addition to the method itself. By [[contrast]], soft X-rays can hardly be said to penetrate [[matter]] at all; for instance, the attenuation length of 600 eV (~ 2 nm) x-rays in [[water]] is less than 1 micrometer. X-rays are a form of ionizing radiation, and exposure to them can be a [[health]] [[Risk|hazard]].<br />
<br />
The distinction between X-rays and [http://en.wikipedia.org/wiki/Gamma_ray gamma rays] has [[changed]] in recent decades. Originally, the [[electromagnetic]] radiation emitted by X-ray tubes had a longer wavelength than the radiation emitted by [http://en.wikipedia.org/wiki/Radioactive radioactive] [http://en.wikipedia.org/wiki/Atomic_nucleus nuclei] (gamma rays).
