Flexible liquid metals of GaIn alloy have been prepared using the melt technique as a novel radiation attenuation material. To determine the radiation shielding performance, the mass attenuation coefficients (μ_m) of samples were calculated using MCNPX and XCOM program within 0.015–15 MeV energy range. Afterward, LACs, HVLs, TVLs, and Z_eff values were obtained to determine the radiation shielding performance. It is observed that Ga₂₀In₈₀ alloy has the most remarkable radiation shielding ability for studied samples. Moreover, the transmission behavior of rays in GaIn alloys was investigated. We simulated the weight of GaIn alloy to be 13% lower than lead with the same transmission coefficient, which is consistent with the XRD experiment. Interestingly, the special fluid property of GaIn alloys imparts an extraordinary self-healing capacity to repair the macro-voids and defects resulting from radiations.

GaIn合金的柔性液态金属已经使用熔融技术制备为新型的辐射衰减材料。为了确定辐射屏蔽性能，使用MCNPX和XCOM程序在0.015–15 MeV能量范围内计算了样品的质量衰减系数（_μm）。之后，获得LAC，HVL，TVL和Z _eff值，以确定辐射屏蔽性能。观察到Ga ₂₀ In ₈₀合金对研究样品具有最出色的辐射屏蔽能力。此外，还研究了射线在GaIn合金中的透射行为。在相同的透射系数下，我们模拟了GaIn合金的重量比铅低13％，这与XRD实验一致。有趣的是，GaIn合金的特殊流动性赋予其非凡的自我修复能力，可修复由于辐射而产生的大孔隙和缺陷。
