A significance criterion was formulated for the effect of physical factors on the quality of the dual high-energy identification of the material of an inspected object. Some recommendations on its practical application are given. A series of calculations on the estimation of the effects of different physical factors on the quality of identification was performed for an MIB 4.5/7.5 small commercially produced betatron. The considered factors were the deviation of the maximum energy high-energy X-rays from the nominal values, the radiation scattered in an inspected object, and the radiation scattered in the structure of a customs inspection complex. These studies proved the necessity of taking the considered factors into account in the design of customs inspection complexes with the possibility of the dual high-energy identification of the material of an inspected object and its fragments.
