Simulations of the radiation environment at ISS altitudes

In order to evaluate and simulate the response of detectors, for measurements of radiation environment inside and outside the International Space Station (ISS), a model for the outside space radiation environment at the altitudes of ISS is required. This estimation can be performed by using e.g. one of the two web-based model packages: CREME96 (Cosmic Ray Effects on Micro Electronics) and SPENVIS (the SPace ENVironment Information System). The main goal of this work is to compare and evaluate these web interfaces and the results given in order to understand how these will influence the simulations of experiments on the ISS.
