In this work, halo orbits about the polymer composites and multilayer materials that can serve as radiation shielding screens. The solution is to analyze the process of radiation effects on composite and multilayer structures, to simulate the process of the effect of cosmic radiation on them, and to compare the results with classically used materials. In the process of work, the effect of radiation on materials based on the Monte-Carlo method was studied. The GEANT4 program in C ++ and TRIM / SRIM is used to calculate the passage of particles through a substance. Mathematical modeling of the passage of electrons and ions through radiation shielding screens has been carried out. The modeling shows the polymer composite screens are lighter compared to traditional aluminum alloy screens, and in multi-layer screens, the degree of protection from radiation depends on the location and composition of the alternating layers. The results of this work may be useful for optimize the construction of radiation shielding screens.
