Multi-energy radiography on the basis of “scintillator–photodiode” detectors

Abstract For reconstruction of the spatial structure and thicknesses of complex objects and materials, it is proposed to use multi-radiography with detection of X-ray or gamma-radiation by combined detector arrays of “scintillator–photodiode” type. Experimental studies have been carried out of the energy dependence of sensitivity of dual-energy inspection systems based on scintillators ZnSe(Te) and CsI(Tl).
