Abstract: Radiation of different objects by the intense flows of X-rays and gamma rays results to the appearance of the whole number of phenomena called System Generated Electromagnetic Pulse (SGEMP). Generation of electromagnetic fields by the assembly of electrons emitted from the interior and exterior surfaces of the illuminated object is the basis of SGEMP.
The present paper contains the results of computational technology designed for the forecasting of the electromagnetic effects in complex three-dimensional objects which appear under the influence of X-rays and gamma-rays. In its basis there is a hierarchical system of mathematical models created on the equations set of Maxwell–Vlasov for describing of physical processes typical for SGEMP and the system of geometrical models of the object under consideration.
