title: Radiation protection strategies in HERMES missions.
abstract: This paper describes the environment of radiations for the HERMES spaceplane and the doses received by men for several missions.  Safeguard strategies are then studied to avoid dangerous dose levels.  In particular, an anomalously large solar event with eruption of energetic protons may lead to inacceptable dose levels.  Strategies, with regards to the orbits characteristics, are discussed.
