In the paper it has been shown the possibility to use large area dispersed scintillators based on ZnSe:Al scintillation screens having a maximum luminescence in photoabsorption of zinc selenide instead of X-ray film for defectoscopy of metal products. Experimental data on influence of X-ray absorption by the samples using scintillation screens based on zinc selenide chalcogenide scintillator and ERS-S-2A on the thickness of the sample at an acceleration voltage in kV are reported. Prospects of using the zinc selenide composite screens in imaging of biological objects are shown, which proves the possibility of using these screens in tomographic medical systems.
