    "abstract": "Multi-energy radiography is a new direction in non-destructive testing. Its\nspecific feature is separate detection of penetrating radiation in several\nenergy channels. Multi-energy radiography allows quantitative determination of\nthe atomic composition of objects. This is its principal advantage over\nconventional radiography. In particular, dual-energy radiography allows\ndetermination of the effective atomic number of a material with an accuracy of\nup to 80-90%. Development of three-energy radiography and radiography of higher\nmultiplicity makes it possible to further improve the reconstruction of an\nobjects chemical composition. This presents the possibility, for example, of\ndetection of explosives and other illegal objects in luggage with a reliability\napproaching 100%. These developments can find application not only in\nanti-terrorist activities, but also in areas such as industrial testing and\nnuclear medicine.",
