Evaluation of Absorbed Dose in Shielding Glass Exposed to Ionizing Radiation Fluxes.

For the first time in a wide range of energies of protons (from 0.1 to 400 MeV) and electrons (from 0.04 to 7 MeV), using the Spenvis database and software of the European Space Agency, proton and electron fluxes have been calculated in accordance with the operating conditions of the SamSat–ION nanosatellite in a sun-synchronous orbit (SSO). In accordance with the spectral energy characteristics of these fluxes, the ionization and radiation losses have been calculated for radiation shielding glass K-208 and SiO2 and, in addition, the annual absorbed dose has been determined using empirical formulas. The results of computation of the integral fluxes in the radiation shielding glass K-208 and SiO2 of various thicknesses irradiated with protons and electrons in a circular SSO are presented, and the proportion of the particles passed through in the single-layer stack approximation is shown.
