Аннотация

One of the approaches to define the “effective atomic number” concept is applied to the main implementations of the dual energy method. The approach is based on the preliminary radiography of special test objects formed from fragments of simple chemical substances and differing in mass thickness and atomic number. The algorithm is easily adapted for inspection systems and X-ray computed tomography using the dual energy method to recognize the materials of test objects or its structural fragments. An example of calculation of the effective mass thickness and the effective atomic number for two-layer objects from carbon and aluminum is given.
