In this work, several models such as GEANT4, PHITS, and HZETRN/OLTARIS are used to predict the radiation environment caused by galactic cosmic rays on Mars in order to compare and validate them with the experimental results. Although good agreement is found in many cases for GEANT4, PHITS and HZETRN/OLTARIS, some models still show large, sometimes order of magnitude, discrepancies in certain particle spectra. We have found that RAD data is helping make better choices of input parameters and physical models. These results help to predict dose rates for future manned missions as well as to perform shield optimization studies.

Times Cited Count：17 Percentile：73.75(Instruments & Instrumentation)The PHITS code is a three-dimensional Monte Carlo code that is able to simulate the transport of nuclei and other particles in complicated geometries. As a part of a comprehensive benchmarking program, we have investigated the possibility of using PHITS to calculate partial charge-changing cross sections and we have compared the results with measurements. The results suggest that the current reaction-cross-section models might be inadequate for use in space radiation protection: We therefore claim the need for a thorough benchmarking of the models and for new reaction-cross-section measurements and experimental techniques.
