Using Geant4 toolkit the changes of the flux density and of the dose rates of the secondary cosmic radiation at the heights up to 50 m from the land surface (at a depth of atmosphere about 1030 g/cm²) and depending on solar magnetic activity were estimated. For changes of Wolf's number (sunspots) in the range of 0 — 200 the flux density of reflected from air and the soil g- and b- particles changes from 5.7 to 7 and 0.10 – 0.13 m-²s-¹ respectively, for energy from 0 keV to several units of GeV in the ground atmosphere on one meter from the earth. These estimates are much lower than those estimates, for radiation created by the soil and atmospheric radionuclides, which had been received earlier. In comparison with a contribution of radionuclides of the soil of flux density of secondary cosmic radiation about 0.01
Keywords: cosmic radiation, atmosphere, background radiation, Wolf's numbers.
