Abstract:
When primary cosmic ray particles come into the atmosphere of the Earth, the secondary particles generated through nuclear reactions with atomic nuclei reach the low altitudes of the atmosphere. The distribution in energy of cosmic ray nucleons from 10 GeV up to the energy characteristic of the knee region of the energy spectrum of the cosmic rays and radiation dosimetry are presented here. The theoretical interpretations of the elemental composition of the primary cosmic radiation suggested that the cosmic ray protons are the main component of the primary cosmic radiation in the terrestrial and space environments. Conclusion is that, the calculated flux of cosmic ray particles decreases with increasing energies as shows the primary proton and nucleon spectra presented in this study.
