| Abstract: | Atmospheric ionization rate for the incident electrons and heavy nuclei (protons and α-particles) of various origin is simulated using GEANT4 code. The photon-nuclei cascade generated by a primary particle is included in this code. “Secondary” bremsstrahlung effect from electrons causes peak ionization at low altitudes along with the more powerful peak at high altitudes. The contribution of helium to the total ionization rate, which turns out to be ～10% of that of protons, is discussed. |
