Very energetic electromagnetic radiation with wavelengths intermediate between 0.01 and 10 nanometers (0.1-100 Angstroms) or between gamma rays and ultraviolet radiation. Essentially all X-Rays from space are absorbed in the Earth's upper atmosphere.
high-energy electromagnetic radiation emitted by atoms when electrons fall from a higher energy shell to a lower energy shell. These rays have high energy and a short wave length. X-rays are very similar to gamma rays. Gamma Rays return to: [] [ Click "BackButton" for previous location
1. Electromagnetic radiation with a very short wavelength (0.01 to 12 nanometers), shorter than ultraviolet radiation. 2. An image created by short-term exposure of an object to x-rays used in spectrometry analysis and medical therapy.
High-energy radiation used in low doses to diagnose disease and in high doses to treat cancer.
Photons or electromagnetic radiation produced by the de-excitation of bound atomic electrons. The energy of an x-ray is equivalent to the difference in energy of the initial and final atomic state minus the binding energy of the electron. Synonym: (Obsolete) x radiation. Related to electromagnetic radiation. Related to gamma ray. Related to photon. A symbol for yotta. A symbol for yttrium.
Diagnostic procedures to study internal structures not visible to the naked eye.
Radiations of very short wavelengths, beyond the ultraviolet in the spectrum.
very short wavelength radiations beyond the ultraviolet in the spectrum, which are about one ten-thousandth as long as the visible violet and are extremely penetrating
Relatively high-energy photons within the approximate range of 0.05 angstroms to 100 angstroms. A stream of these photons have a very effective penetrating power. Solar x-rays create geomagnetic storms.
X-rays were used in medical experiments in the women's camp in Birkenau. "Dr." Horst Schumann used X-rays to sterilize his innocent victims, young men and women, who usually died very painful deaths shortly thereafter.
Energetic electromagnetic radiation. Energy-wise, X-rays fall between gamma rays (more energetic) and ultraviolet radiation.
Plain radiographs, usually taken when there is a history of trauma, to exclude fractures. Also used to confirm degenerative disease processes. Non-specific investigation for soft tissue injuries.
These are usually taken of teeth before a dentist will allow a bleaching to be allowed, to check that the teeth involved do not have cavities. X-Rays can sometimes be referred to as `radiographs.'
Having an x-ray is a prophecy of mysterious occurrences for one of your friends.
Electromagnetic waves with a wavelength between those of ultraviolet and of gamma rays.
Electro-magnetic radiation. Used by man as a treatment for some stones to enhance their beauty.
radiation of extremely short wavelength that can pass through various solids. X-rays are used to diagnose, photograph, and even treat certain medical conditions. While a patient's exposure to radiation while an x-ray is being taken is quite low, body parts not being x-rayed may be shielded.
(a) Photons of wavelengths between about 0.1 Å and 100 Å - more energetic than ultraviolet, but less energetic than -rays. [H76] (b) A large band of electromagnetic radiation with wavelengths smaller than extreme ultraviolet light. A typical X-ray photon has over one thousand times as much energy as a photon of visible light. [McL97
Electromagnetic radiation with much smaller wavelength and much higher energy than visible light. We encounter X-rays in our daily lives for example in medical imaging devices and security screening machines. Type of radiation: X-rays
A form of electromagnetic radiation with a wavelength in the range of 10 to 0.01 nanometers, corresponding to frequencies in the range 30 to 3000 PHz (1015 hertz). X-rays are primarily used for diagnostic medical and industrial imaging as well as crystallography. X-rays are a form of ionizing radiation and as such can be dangerous. N/A A 70-200mm Zoom lens
Electromagnetic radiation emitted by atomic electrons.
A tooth x-ray is usually taken before a dentist will allow bleaching, in order to ensure that the teeth involved do not have cavities. X-Rays can sometimes be referred to as `radiographs.'
The portion of the electromagnetic spectrum that has a very short wave length. It has a wave length longer than gamma rays, yet shorter than visible light. X-rays can penetrate various thicknesses of all solids, and when absorbed by a gas, can result in ionization.
X-rays are 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. X-ray images of celestial objects are one way of learning about their high-energy properties. For example, the sun's corona emits X-rays, especially over sunspots. The Einstein X-ray satellite was launched in 1978 to survey celestial X-ray sources.
