English term or phrase: scintillator
Definition from European Nuclear Society:
Substance in which flashes of light are generated by impinging ionizing radiation (fluorescence). Nal(Tl)-monocrystals are particularly suitable for the detection of gamma radiation and anthracene or diphenyl oxazole dissolved in toluene is suitable for beta radiation. ZnS(Ag) is a favourable scintillator for detection of alpha radiation.

Example sentence(s):
  • Gadolinium silicate doped with cerium is a "fast" crystal and can be used as a protection scintillator. Its possible applications include computer tomography, spatial resolution of less than 1 mm. Marketech International
  • YAG (Yttrium Aluminum Garnet) single crystal scintillators are chosen by many scanning electron microscopists because they have a very fast response time of 50 - 60ns and (unlike plastic or most phosphor scintillators) they do not degrade when bombarded by electrons or ions. Canemco & Marivac
  • Plastic scintillators are prepared by bulk polymerization in aluminium (size up to 3.5 m) or glass cast and by pressure molding technique. Amcrys-H

الوماض/المادة الوامضة
Definition:
A scintillator is a substance that absorbs high energy (ionizing) electromagnetic or charged particle radiation then, in response, fluoresces photons at a characteristic Stokes-shifted (longer) wavelength, releasing the previously absorbed energy. See also Scintillation (physics). Scintillators are defined by their light output (number of emitted photons per unit absorbed energy), short fluorescence decay times, and optical transparency at wavelengths of their own specific emission energy. The latter two characteristics set them apart from phosphors. The lower the decay time of a scintillator, that is, the shorter the duration of its flashes of fluorescence are, the less so-called "dead time" the detector will have and the more ionizing events per unit of time it will be able to detect.
