LOCAL DOSE LOAD FROM A FLAT SEMI-INFINITE PROTECTION AT AN ARBITRARY POINT

A model of the local dose load from the electron and proton radiation of outer space at an arbitrary point lying behind a flat limited protection has presented. The model is based on the use of the ray method or the sectorization method. Unlike the currently used models, which determine the dose load at a point lying perpendicular to the plane behind the protection, the proposed model allows you to determine the dose load at any point. Such a model can be useful for protection against ionizing radiation having a heterogeneity of mass thickness, for example, when using additional protection for sensitive electrical devices or taking into account the shadow effect from other spacecraft structures or other similar cases. A numerical experiment has conducted for an orbit with a distance of about 400 kilometers from the Earth's surface.
