The account of influence of forms-factors on angular distribution of photons at numerical modelling transformations of X-ray radiation in objects

E. G. Luk'yanova, S. V. Podolyako


Abstract: The algorithm for research of various types of interaction of photons ionizing radiations with materials of multi-component objects in three-dimensional geometry is offered. The specified algorithm is realized as a complex of parallel programs. The analysis of results of the carried out calculations has shown, that in a number of situations the account of the considered physical factors renders essential influence on intensity and spatial distribution transformed ionizing radiations. Research of influence on characteristics of absent-minded radiation of changes of angular distributions of the absent-minded photons caused by influence connected nuclear electrons is carried out, depending on a material of object and power of quantum. The received results are supposed to be used, in particular, at research of processes of formation of streams electrons at passage X-ray and g-radiations through objects.
