Scope note: Radiación electromagnética penetrante emitida cuando se excitan los electrones de la órbita interna de una átomo y liberan energía radiante. Las longitudes de onda de los rayos X varían entre 1 pm y 10 nm. Los rayos X duros son los rayos X de mayor energía y de menor longitud de onda. Los rayos X blandos o rayos Grenz tienen menos energía y una mayor longitud de onda. El extremo de la onda corta del espectro de los rayos X se solapa con el rango de la longitud de onda de los RAYOS GAMMA. La distinción entre los rayos gamma y los rayos X se basa en su fuente de irradiación.

Scope note: Penetrating electromagnetic radiation emitted when the inner orbital electrons of an atom are excited and release radiant energy. X-ray wavelengths range from 1 pm to 10 nm. Hard X-rays are the higher energy, shorter wavelength X-rays. Soft x-rays or Grenz rays are less energetic and longer in wavelength. The short wavelength end of the X-ray spectrum overlaps the GAMMA RAYS wavelength range. The distinction between gamma rays and X-rays is based on their radiation source.
Annotation: diagnostic use of X-rays = RADIOGRAPHY + specific disease /diag image; therapeutic use of X-rays = X-RAY THERAPY (general) or /radiother with specific diseases; X-ray or x-ray in translations: follow text
Allowable Qualifiers: AE adverse effects
