A special version of the SHIELD transport code has been developed intended for radiation protection purposes in space. The calculation of the fluxes of primary and secondary particles and the absorbed dose rate in a water phantom behind various shielding under the influence of galactic cosmic rays (GCRs) using the GCR model developed by the Institute of Nuclear Physics, Moscow State University. The code architecture is briefly described as a version of SHIELD including models of nuclear reactions. Stopping power dE/dX(E) is calculated in the energy range of 10 keV/nucleon–100 GeV/nucleon. The calculation was performed in spherical geometry, which allows, in a simple formulation of the problem, to compare the fluxes of particles of different types in the phantom, as well as to estimate the contribution to the dose of different GCR components depending on the protection parameters.
