On the base of satellite measurements in the 21- and 22-th solar cycles is developed a model of the electron component of the Earth radiation belts. Spatial electron distributions are obtained at 350, 500 and 800 km in the minimum and maximum of the solar cycle. Global changes are noted in the spatial radiation distribution near the Earth in comparison with 1965-1972, namely decreasing trapped electron fluxes and increasing quasi-trapped oned at small heights and variations in the spectrum in the region of the inner radiation belt. A model of trapped protons is developed which permits to precise flux forecasting owing to corrections accounting for Earth magnetic moment decreasing and atmospheric cutting off. 13 refs.; 2 figs.; 5 tabs.
