Passive radiation shielding alone cannot provide adequate protection for astronauts on long-term, deep-space missions. High atomic number and energy (HZE) ions, and/or their secondaries, can penetrate any realistic mass shielding for long-term deep-s

Passive radiation shielding alone is insufficient for protecting astronauts from galactic cosmic ray exposure. Active shields, utilizing electromagnetic fields to deflect heavy charged ions in space, could be used to supplement conventional passive s

Risk due to space radiation exposure is one of the prime concerns for astronaut health and safety on deep space missions. NASA's current radiation risk limit is 3% risk of exposure-induced death (REID) at the upper 95% tolerance limit. Sex and age de
