THE DOSIS AND DOSIS 3D PROJECT ON-BOARD THE INTERNATIONAL SPACE STATION - CURRENT STATUS AND SCIENCE OVERVIEW

Kurzfassung

The radiation environment encountered in space differs in nature from that on earth, consisting mostly of high energetic ions from protons up to iron, resulting in radiation levels far exceeding the ones present on earth for occupational radiation workers. Accurate knowledge of the physical characteristics of the space radiation field in dependence on the solar activity, the orbital parameters and the different shielding configurations of the International Space Station (ISS) is therefore needed. For the investigation of the spatial and temporal distribution of the radiation field inside the European Columbus module the experiment \Dose Distribution Inside the ISS" (DOSIS), under the project and science lead of DLR, was launched on July 15th 2009 with STS-127 to the ISS.
