Abstract: The high energy particles (electrons and protons) passing through the lower atmosphere of Venus are attenuated and produce ionization of atmospheric constituents. In this paper, the loss of energy of electrons (105 < E < 108 eV), protons (107 < E < 1012 eV), and Bremsstrahlung radiation due to electrons of energy 104 < E < 108 eV have been computed. The results are used to study the impact and Bremsstrahlung photoionization in lower ionosphere of Venus. The production rate due to the attenuation of energetic particles has been evaluated. It is shown that the production rate due to non-relativistic protons is dominating above 100 km, whereas below this height extreme relativistic protons are effective and produce a peak at the height of 65 km.
