n1. (General Physics) a. electromagnetic radiation emitted when matter is bombarded with fast electrons. X-rays have wavelengths shorter than that of ultraviolet radiation, that is less than about 1 × 10–8 metres. They extend to indefinitely short wavelengths, but below about 1 × 10–11 metres they are often called gamma radiationb. (as modifier): X-ray astronomy. 2.

What does it mean when you dream about an X-ray?
Being X-rayed in a dream may signal wanting to see through a situation or the intentions of someone who is emotionally significant in one’s life.
X-Ray
(dreams)Dreaming about getting an X-ray or looking at an x-ray may not have anything to do with health matters. This dream suggests that you are ready to look beneath the surface of a current situation or problem. X-rays require focused energy and your dream may be a reflection on the energy that you already possess. This energy will assist you in gaining insight and awareness or help you with problem solving. Old dream interpretation books say that dreaming of X-rays is a dream of the contrary. That is, you will be released from your worries and enjoy good health.

X-ray
High-energy radiation A range of the electromagnetic spectrum used in low doses to diagnose disease and in high doses to treat CA. See Soft X-rays. X-ray exposureDiagnostic x-rays Impart 30-150 keV of energy; rare reports vaguely suggest a relationship between exposure to low- level X-rays and a slight ↑ in myeloproliferative disorders and a minimal ↑ risk for developing myeloma Therapeutic x-rays • Low level radiation, eg 5-10 keV or 'grenz' radiation–may be used to treat recalcitrant skin conditions–eg, psoriasis • High level radiation, eg megaelectron-volt–MeV) radiation–may be used to treat internal malignancy

Ionizing electromagnetic radiation produced by the excitation of the inner orbital electrons of an atom by other processes, such as nuclear delay and its sequelae. 3. A radiograph. Synonym(s): roentgen ray.
X-ray
A form of electromagnetic radiation produced when a beam of high-speed electrons, accelerated by a high voltage, strikes a metal, such as copper or tungsten. X-radiation penetrates matter to a degree depending on the voltage used to produce it and the density of the matter. It acts on normal photographic film in much the same way as does visible light, but can also produce an image on a fluorescing screen. These properties make X-radiation valuable in medical diagnosis. X-rays are damaging to tissue, especially rapidly reproducing tissues, and can be used to treat various cancers (see RADIOTHERAPY).
X-ray
an ionizing radiation that is a powerful MUTAGEN with wavelengths between 10–1 and 10 nm on the ELECTROMAGNETIC SPECTRUM. X-rays are produced by bombarding a metallic target with fast electrons in a vacuum, and are capable of penetrating various thicknesses of solids. Having passed through a solid they can act on a photographic plate producing a light/shade pattern indicative of the solid structure.
