IUPAC - scintillation counter (S05504)

scintillation counter

A scintillator coupled to a @P04626@. Incident X-ray photons are converted in the scintillator into bursts of @VT07496@ light photons, some of which fall on the photocathode and can be measured. For incident photons having energies higher than the absorption edge of the elements contained in the scintillator, an escape peak can be observed.
