Validation of flux models to characterize the radiation environment in space based on current Rosetta-data

Abstract

With increasing interest in interplanetary manned space missions, the galactic cosmic radiation (GCR) background gains more and more relevance. Therefore, validating this radiation environment using existing flux models is of paramount importance. Hence a continuous development of these theoretical models is necessary. In this work, the flux model adopted by ISO 15390 is verified using Monte Carlo simulated response functions of the Standard Radiation Environment Monitor (SREM). Within the typical error estimates the principal count rate evolution of the SREM detector due to the GCR background could be consistently modelled with the proposed method.
