RT Journal Article T1 Overview of the main radiation transport codes A1 Schetakis, Nikolaos A1 Crespo, Rodrigo A1 Luis Vazquez-Poletti, Jose A1 Sastre Marugán, Mariano A1 Vazquez, Luis A1 Di Iorio, Alessio AB Accurate predictions of expected radiation dose levels on Mars are often provided by specific radiation transport codes that have been adapted to space conditions. Unsurprisingly, several of the main space agencies and institutions involved in space research and technology tend to work with their own in-house radiation codes. We present the codes that are related to the simulation of the radiation on Mars' surface under different scenarios. All of these codes have similar fields of application, but they differ with respect to several aspects, including the energy range and types of projectiles considered as well as the models of nuclear reactions considered.
