Fig. 4: Calculated and experimental evaluation of X-ray shielding performance of Ga/In-Bi composites.
From: Non-toxic soft shielding materials for wearable X-ray protection

a–d Ga/In-Bi composites with varying Ga/In ratios and the maximum Bi concentration that retains a soft state. Calculated shielding parameters: a μ, b μm, c HVL, and d Zeff. e–i Ga/In-Bi composites with different Bi contents (5, 15, 25, and 35 wt%) at a fixed 50/50 Ga/In weight ratio. e Schematic illustration of the experimental X-ray attenuation setup used for measuring transmission through the composite. f Calculated results for Zeff. Comparison between calculated and experimentally measured g μ, h μm, and i HVL values. The inset plot highlights the experimentally measured results, including re-tested samples to assess long-term stability after two months. All plotted as a function of photon energy (1–1000 keV). j Comparison of recently reported Bi-based shielding materials with Ga/In-Bi composites.
