Query: Multi-energy radiography on the basis of "scintillator-photodiode"
  detectors   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 $CsI(Tl)$.
