Simulation results of characteristics of atmospheric $\gamma$- and $\beta$-radiation fields, which are produced by primary cosmic rays when overcoming an Earth’s atmospheres, with using Geant4 are presented. Estimates of $\gamma$- and $\beta$-radiation flux density with energies of 50 keV-3 MeV formed in ground atmosphere by cosmic radiation are 33 and 1.5 m$^{-2}$; s$^{-1}$, approximately, that is significantly lower than that formed by soil and atmospheric radionuclides. It was received that the contribution of cosmic component into the total $\gamma$- and $\beta$-background of the ground atmosphere at the heights of about 50 m from the land surface is only about 0.06 % and 1.14 %, respectively. The barometric effect within various ranges of energies of photons and electrons was also investigated in the work.
Mots-clés : simulation, Geant4.
