According to the data from the SONG instrument on board the low altitude high inclination CORONAS-I satellite, the fluxes of gamma rays with energies between 120 keV and 8.3 MeV are reviewed. The observations were made during the interval from May 1994 to early July 1994. Comparison with energetic electron fluxes obtained from AE-8 model is done, and thus the gamma-ray production mechanism is discussed. Available data are used to investigate the fine spatial structure in the Brazilian anomaly, as well as to analyse outer zone of bremsstrahlung electrons. To do this, the L-B maps are constructed and energy spectral characteristics of gamma-ray fluxes are investigated.
