Bismuth radiation shielding
WebSep 17, 2024 · Bismuth nanoparticles are made with cellulose nanofibers and dispersed evenly into a polymer. A four time reduction in the mass of bismuth material is identified at 2% mass ratio when nanoparticles (5 nm in diameter) are used in composite to shield a given flux and energy of radiation, in relative to those of microparticles (5 μm diameter). WebJul 1, 2024 · Radiation shields are defined as any material that can absorb radiation and, therefore, decrease its intensity to safe levels. Commonly used radiation materials include alloys, concretes, and glasses. Concretes offer great structural support and are frequently used to attenuate, or absorb, X-rays [2], [3].
