Abstract
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 (μm) of samples were calculated using MCNPX and XCOM program within 0.015–15 MeV energy range. Afterward, LACs, HVLs, TVLs, and Zeff 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.
