FIELD: physics.
SUBSTANCE: interaction of multienergy radiation is carried out with the checked object, measuring and recording the measured quantities after interaction of multienergy radiation with the checked object, substitution of a part of the measured values in preliminary determined calibration function for obtaining of the information containing major importance of the performance of object and more exact determination of the performance of material of object by application of a set of functions, suitable for energy line corresponding to the gained information.
EFFECT: possibility of identification of various materials in a wide range of atomic numbers.
