X-ray, английский
- 1. a ray with a very short wavelength, which is invisible, but can go through soft tissue and register as a photograph on a film. x-rays are used in diagnosis in radiography, and in treating disease by radiotherapy. the x-ray examination showed the presence of a tumour in the colon. 2. a photograph taken using x-rays the dentist took some x-rays of the patient’s teeth. he pinned the x-rays to the light screen. 3. an examination in which x-ray photographs are taken all the staff had to have chest x-rays. verb to take an x-ray photograph of a patient there are six patients waiting to be x-rayed. comment: because x-rays go through soft tissue, it is sometimes necessary to make inter- x-ray imaging 458 nal organs opaque so that they will show up on the film. in the case of stomach x-rays, people take a barium meal before being photographed (contrast radiography); in other cases, such as kidney x-rays, radioactive substances are injected into the bloodstream or into the organ itself. x-rays are used not only in radiography for diagnosis but as a treatment in radiotherapy as rapidly dividing cells such as cancer cells are most affected. excessive exposure to x-rays, either as a person being treated, or as a radiographer, can cause radiation sickness.

X-ray absorption fine structure, английский
X-ray absorption near edge structure, английский
X-ray analysis, английский
The use of x-ray radiation to detect heavy elements in the presence of lighter ones, to give critical-edge absorption to identify elemental composition, and to identify crystal structures by diffraction patterns.

X-ray diffraction, английский
The scattering of x-rays from a crystal, resulting in an interference pattern used to determine the structure of the crystal.
X-ray film (rt), английский
A film base that is coated (usually on both sides) with an emulsion designed for use with xrays.
X-ray fluorescence, английский
A diamond’s ability to emit secondary x-rays when it is exposed to an x-ray. this characteristic is used to identify a diamond or other stone by indicating its chemical elements.

X-ray lenses, английский
Occupational high index glass lenses offers protection from gamma ray energy present in x-ray radiation. the material is colorless and very heavy due to the high amount (70%) of lead oxide that glass contains. these lenses cannot be hardened. y “y”-axis –a symbol used for imaginary line perpendicular to the x-axis. the 90? line.
X-ray paper (rt), английский
White paper coated on one side with emulsion for use with or without an intensifying screen. it is suitable for use with x-rays. x-ray spectrometer (rt)
