Abstrakt: Physical and geometric models of heterogeneous porous media are constructed with direct allowance for their microstructure. A method is worked out for calculating the probability distributions of the energy and momenta of radiation particles interacting with a material of a complex chemical composition. The distributions are used for detailed simulation of the scattering and absorption of radiation in complex heterogeneous materials. An approach is developed for the discrete description of the realistic geometry of porous heterogeneous media taking into account their structure at the microlevel. The approach includes an algorithm for constructing a detecting system for the statistical estimation of the radiation energy release during its propagation in an object. The results of model calculations on a hybrid computing cluster K-100 are presented. [ABSTRACT FROM AUTHOR]
