Abstract An approach to calculate the initial data for computer simulation of radiation-induced secondary effects in a heterogeneous medium is considered. A method for solving the problem of integration “according to the data” of the results of modeling cascade processes of radiation transfer and processes of generation of secondary radiation-induced effects is proposed. The method is based on a multidimensional approximation of the results of the statistical modeling of the interaction of radiation with matter on a difference mesh designed for the numerical solution of the equations of electro- and thermodynamics. The approximation is built using neural network technology. The geometric model of a heterogeneous medium is based on the Stillinger–Lubachevsky algorithms for multimodal structures. The results of demonstration calculations are presented.
