originally, any of the rays produced when cathode rays strike upon surface of a solid (as a copper target or the wall of the vacuum tube); now defined as electromagnetic radiation with a wavelength of 0.1 to 10 nanometers. X-rays are noted for their penetration of many opaque substances, as wood and flesh, their action on photographic plates, and their fluorescent effects. They were called X rays by their discoverer, W. K. Röntgen, but were also referred to for some time as Roentgen rays. The term X-ray has become the most common designation. They also ionize gases, but cannot be reflected, or polarized, or deflected by a magnetic field. They are used in examining objects opaque to visible light, as for imaging bones or other structures inside the human body, and for detecting flaws in metal objects, such as in welds.
to examine by means of X-rays; to irradiate with X-rays.
Electromagnetic radiation of short wavelength used to penetrate tissues and record densities on film. Sometimes used to aid in diagnosis of LSDs.
A class of high energy photon, X-rays have wavelengths of 0.012 to 12 nanometers. Not only are X-rays used for medical imaging (when you break your arm an X-ray machine is used to take a picture of the broken bone), but since black holes, quasars, and other stellar objects emit X-rays, X-Ray Astronomy is actively researched.
A photon of electromagnetic radiation in the wavelength interval between about 1 Angstrom and 100 Angstroms.
A type of electromagnetic radiation (between ultraviolet light and gamma rays in wavelength, frequency, and energy) - basically, it's light that is way past the blue-violet end of the visible spectrum - we cannot see it. They have short wavelength (and high frequency) as compared to visible light. Each photon of X-ray radiation has a lot of energy. X-rays can go through most solid objects.
Electromagnetic radiation of very short wavelength, lying within the wavelength interval of 0.1 to 1.5 angstroms (between gamma rays and ultraviolet radiation). X-rays penetrate various thicknesses of all solids, and they act on photographic plates in the same manner as light. Secondary x-rays are produced whenever s-rays are absorbed by a substance. In the case of absorption by a gas, this results in ionization.
a type of high energy radiation that can be used at low levels to make images of the internal structures of the body and at high levels for radiation therapy
a diagnostic technique when an electromagnetic wave produces an image of internal body parts.
Electromagnetic radiation with wavelengths between those of ultraviolet and gamma rays, approximately 0.01-10 nm. At these short wavelengths, it is more common to talk in terms of photon energies. These energies range from 0.1-100 k eV.
Higher-energy part of the X-ray spectrum ranging from approximately 5 k eV to 100 keV.
electromagnetic radiation produced outside the atomic nucleus by machines.

The use of high-energy radiation from x-rays to kill cancer cells and shrink breast tumors. Radiation may come from a machine outside the body (external-beam radiation therapy) or from materials called radioisotopes. Radioisotopes produce radiation and can be placed in or near the tumor or in the area near breast cancer cells. This type of radiation treatment is called internal radiation therapy, implant radiation, interstitial radiation, or brachytherapy. Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that circulates throughout the body. X-ray therapy is also called radiation therapy, radiotherapy, and irradiation.

The X-ray is: photon of high energy, short wavelength electomagnetic radiation that is not made up matter at all…. it is pure energy. the result of an atomic electron transition for a very heavy element. It is produced in an X-ray tube. High energy electrons are fired at a metal (usually tungsten) target within an evacuated tube. The interaction of these high energy electrons with the electrons orbiting the metal atom produces X-rays - they are NOT nuclear radiation (cf gamma ray production). Some very powerful X-ray machines can produce X-rays that are of higher energy than most gamma rays. (see LINAC) Having no mass and no charge its ionising power is very low. As its ionising power is so low it penetrates very deeply into matter before its energy has been used up. Its penetrating power is therefore very high (about 99.9% is absorbed by 100 m of air or 1cm lead).
Electromagnetic radiation of non-nuclear origin within the wavelength interval of 0.1 to 100 Angstroms (between gamma-ray and ultra-violet radiation). X-rays are used in medicine to examine teeth, lungs, bones, and other parts of the human body; they also occur naturally.

X-ray emissions are associated with high-energy astrophysical events such as accretion onto neutron stars and black holes.

In low doses X-rays are used for making images that help to diagnose disease, and in high doses to treat cancer . Formerly called a Roentgen ray. An image obtained by means of X-rays. See the entire definition of X-ray
(Or x-radiation, RÃ¶ntgen ray.) Electromagnetic radiation with wavelengths shorter than that of ultraviolet radiation and greater than that of gamma radiation. Discovered accidentally by RÃ¶ntgen in 1895. The primary mechanism for the production of x- rays is deceleration of a rapidly moving charge upon interaction with matter ( bremsstrahlung). The x-ray spectrum from an x-ray tube consists of this continuous spectrum on which are superimposed narrow bands (characteristic radiation) that are a consequence of transitions between electronic energy levels of atoms. No sharp boundary exists between x- and ultraviolet radiation nor between x- and gamma radiation, although the latter term is usually restricted to radiation resulting from transitions between nuclear energy levels.
