The technology of flexible panels and dispersed scintillation elements for X-rays registration with high uniformity of scintillation parameters (mean deviation no more than 2%) and low cost is developed. Parameters of flexible scintillation panels have been optimized, which enable their obtaining with high spatial resolution. The panels can be used as intensifying screens in medical and industrial radiography. Variants of the performance of the dual energy X-ray detectors, working effectively in X-ray energy region (from 20 to 100 keV) are proposed. Possible areas of their application - multienergy scanners and medical computer tomography.
