An analysis is presented of the quasi-periodic background gamma radiation variations and electron flux measurements at various altitudes and geomagnetic latitudes, obtained during two balloon flights equipped with a gamma ray telescope, registering energies exceeding 40 MeV. The possible mechanisms of quasi-periodic variations are discussed, and it is noted that the variation is most probably caused by atmospheric internal and gravity waves with a density variation amplitude greater than 10% at an altitude of about 40 km. The analysis indicates an anisotropic modulation of gamma radiation with a characteristic spatial dimension of several tens of degrees. The stratospheric (35-40 km) electron flux anisotropy in the equatorial region is discussed. Data are compared with those obtained at satellite altitudes.
