Satellite Carried Electronic Equipment Box Irradiation Protection Theory Study

The development of space technology makes people pay attention to the outer space of the Earth . People's space activity area gets larger and larger and electron equipments are widely applied to the space exploration activity . But the natural space radiation environment are full of lots of dangers and doesn't make electron equipment work naturally. So space radiation protection becomes an important study problem of people's space activity.This paper analyses the box receiving space radiation complexion in low earth orbit rang for the outer radiation environment generally and superficially conceive of study the work about the space radiation protection simulation calculation software to the box, which is based on space radiation protection need. The paper expatiates the material working environment of electron equipment box; according to the difference of the particle,mass shielding method is adopted to modeling for the box , calculates a few matter material for the box and its parameter for mass shielding effect. It analyses different box material's effect on the radiation protection , It completes the research box space radiation protection simulation software's primarily design.
