Radiation Analysis for Moon and Mars Missions

Abstract

This paper provides an overview of the radiation aspects of manned space flight to Moon and Mars. The expected ionising radiation dose for an astronaut is assessed along the Apollo 11 flight path to the Moon. With the two dose values, the expected and the measured total dose, the radiation shielding and the activity of the Sun are estimated. To judge the risk or safety margin the radiation effects on humans are opposed. By only changing the flight duration an assessment for the total dose of a journey to Mars is provided.
