The results of GRIF experiment on board the "Spectr" module of "Mir" orbital station concerning to the study of fluxes of electrons with energies >80 keV are presented in this manuscript. The number of instruments included detectors of electrons, protons and nuclei with large and small geometric factor, that allowed to measure high charge particle fluxes in the Earth's radiation belts as well as low electron fluxes at the regions near the geomagnetic equator. The parameters of electron fluxes observed during the all time of experiment from October, 1995 to June, 1977 in the near-Earth space on the drift shells L = 1.7, 1.4, 1.1 are analyzed. The geographic maps, on which electron flux distributions on the station orbit altitude (400 km) are shown, and the spectral estimations indicate on that the most probable source on the shells L < 1.5 is the South-Atlantic Anomaly. By this the stable enrichment of L-shells with L = 1.7, 1.4, 1.1 may be caused by the scattering in the remnant atmosphere of the inner radiation belt electrons precipitating near the South-Atlantic Anomaly.
