Abstrakt: The International Space Station provides researchers with a unique opportunity to develop and test radiation environment models and computational procedures. Since having manned missions into space is an ongoing part of NASA exploration of space, it has become necessary to conceive new methods to determine the safety of the astronauts in that environment. One of the major environmental hazards in space is the radiation an astronaut will be exposed to during their mission. NASA Langley Research Center, working in conjunction with Johnson Space Center, is developing a process that accurately simulates the radiation environment in the International Space Station. The environment includes the shielding provided by the ISS and the radiation environment surrounding the ISS. The radiation shielding is modeled using commercial CAD software. Ray-tracing software is used to calculate the shielding thicknesses for the model. A radiation environment is generated from data acquired from the NASA-GSFC National Space Science Data Center and transport codes for heavy ions and electrons. The radiation dose can then be calculated through combining the thickness files and the radiation environment. Various radiation dose experiments were and still are being performed on the International Space Station. Analysis of the radiation shielding environmental model can be compared to data obtained from the ISS, enabling researchers to perfect their methods of predicting radiation environments and allowing them to create a tool that can be applied to future endeavors into space. © 2003 American Institute of Physics [ABSTRACT FROM AUTHOR]
