A Predictive Code for International Space Station Radiation Mission Planning

Abstract

A model developed for radiation mission planning aboard the International Space Station (ISS) is presented. The model utilizes a correlation between the ambient dose equivalent rate determined by a tissue equivalent proportional counter (TEPC) aboard the ISS and the cut-off rigidity parameter estimated from ISS position vectors. A preliminary assessment indicates the model can predict the total ambient dose equivalent to within 20% of tabulated measurements.
