The International Space Station (ISS) and the earlier station MIR provided the proving ground for future human long-duration space activity. A recent European Space Agency study recommended “…Measurement campaigns on the ISS form the ideal tool for experimental validation of radiation environment models, of transport code algorithms, and reaction cross sections.” Indeed, prior measurements on Shuttle have provided vital information impacting both environment model and transport code development by requiring dynamic models of the Low Earth Orbit (LEO) environment. Recent studies using CAD models of the ISS 7A configuration with TLD (thermo-luminescent detector) area monitors demonstrated that computational dosimetry requires environmental models with accurate non-isotropic as well as dynamic behavior, detailed information on rack loading, and an accurate 6-degree-of-freedom description of the ISS trajectory. The ISS model is now configured for 11A and uses non-isotropic and dynamic geomagnetic transmission and trapped proton models. The ISS 11A is instrumented with both passive and active dosimetric devices. ISS 11A and LEO model validation is an important step in preparation of the design and validation of the Crew Exploration Vehicle (CEV) under the Constellation program. |
