Long Duration, Deep Space Mission Radiation Engineering Analysis of Materials and Astronaut Protection

摘要

The primary finding of this analysis is that for shielding to be provided solely by mass around a deep space vehicle, a large number of heavy lift launches are needed to meet the recommended exposure, an ED of 150 mSv. For the latest Mars mission, it will take 24 heavy lift launches of pure polyethylene to meet the recommended exposure not including the surface stay.
