  "abstract": "Shielding performances of Ta-10W alloy and Pb in CT lateral-scattered radiation fields were compared using NIST XCOM data and MCNP6 models of a tungsten-target source，a PMMA phantom，and flat shielding plates. The air-kerma ratio \\begin{document}$B_k $\\end{document} was used to characterize transmission. As the tube voltage increased from 80 to 140 kVp，the mean energy of the 90° scattered spectrum increased from 47.01 to 57.95 keV，and the air-kerma contribution from 67.4–88.0 keV increased from 2.40% to 19.14%. For the same \\begin{document}$B_k $\\end{document} as 2.5 mm Pb，the equivalent Ta-10W thicknesses were 2.01，1.50，1.37，and 1.33 mm at 80，100，120，and 140 kVp，respectively，corresponding to thickness reductions of 19.56%–46.98%. At 100–140 kVp，the areal density was reduced by 10.67%–21.08%. The mass attenuation coefficient of Ta-10W at 80 keV was about 3.15 times that of Pb. The advantage is attributed to enhanced attenuation above the Ta/W K edges and below the Pb K edge，providing a numerical reference for thin local shielding in CT rooms.",
