noun

1.

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 radiation

b.

(as modifier)

X-ray astronomy

2.

a picture produced by exposing photographic film to X-rays: used in medicine as a diagnostic aid as parts of the body, such as bones, absorb X-rays and so appear as opaque areas on the picture

noun

1.

a band of electromagnetic radiation with wavelengths between gamma rays and ultraviolet radiation (c. .005 to c. 5 nanometers), produced by the bombardment of a substance (usually one of the heavy metals) by a stream of electrons moving at great velocity, as in a vacuum tube: X-rays are capable of penetrating opaque or solid substances, ionizing gases and body tissues through which they pass or, by extended exposure, destroying tissue, and affecting photographic plates and fluorescent screens: they are widely used in medicine for study, diagnosis, and treatment of certain organic disorders, esp. of internal structures of the body

usually used in pl.

2.

n. or x ray or X ray

1.

a. A photon of electromagnetic radiation of very short wavelength, ranging from about 10 down to 0.01 nanometers, and very high energy, ranging from about 100 up to 100,000 electron volts.

b. often x-rays or X-rays A narrow beam of such photons. X-rays are used for their penetrating power in radiography, radiology, radiotherapy, and scientific research. Also called roentgen ray.

2.

a. A photograph taken with x-rays.

b. The act or process of taking such a photograph: Did the patient move during the x-ray?
