Electromagnetic radiation shielding characteristics in conditions of their impact on both human and technical means have been studied. Shown that for efficiency perforated screens necessary to consider the aspect ratio holes, the distance between them and the wave length of shielded and granted the appropriate graphic material. To increase the protective properties of these screens, holes should produce as waveguides. One effective method of reducing reflective properties of these screens is that the waveguides inlets must have a curvature radius of which is calculated based on the experimental data.
