Schematic illustrating the BNNT shielding film with high neutron shielding capability compared to aluminum (IMAGE)
Caption
Space is an environment exposed not only to primary cosmic radiation but also to secondary radiation, particularly neutrons, which are generated by interactions with spacecraft or the lunar surface and pose significant biological risks. The BNNT liquid crystal-based film demonstrates more efficient space radiation shielding performance than aluminum at the same mass thickness, and is especially effective at attenuating thermal neutrons.
