摘要

本研究评估了用当地开采的重晶石矿石制成的混凝土的γ辐射屏蔽性能：高品位重晶石矿石（HGBO），木炭重晶石矿石（CBO）和低品位重晶石矿石（LGBO）。在能量为0.15-0.826 MeV、水灰比为0.6的条件下，采用Phy-X模拟方法，测得HGBO、CBO和LGBO的密度分别为2.37、2.28和2.21 g/cm3。HGBO表现出最高的线性衰减系数（0.15 MeV时为0.330 cm - 1），最低的HVL （2.10 cm）和最佳的热稳定性（1200°C时失重27.4%）。结果证实，HGBO混凝土是一种具有成本效益，环保，无铅的核和医疗应用屏蔽材料。

Gamma shielding evaluation of concrete reinforced with locally mined barite rock ores: a comparative analysis of density and attenuation coefficients

This study evaluates the gamma radiation shielding performance of concretes fabricated with locally mined barite ores: high-grade barite ore (HGBO), charcoal barite ore (CBO), and low-grade barite ore (LGBO). Using the Phy-X simulation method at energies of 0.15–0.826 MeV and a water-cement ratio of 0.6, the measured densities for HGBO, CBO, and LGBO were 2.37, 2.28, and 2.21 g/cm³, respectively. HGBO displayed the highest linear attenuation coefficient (0.330 cm⁻¹ at 0.15 MeV), lowest HVL (2.10 cm), and best thermal stability (27.4% weight loss at 1200 °C). Results confirm HGBO concrete as a cost-effective, eco-friendly, lead-free shielding material for nuclear and medical applications.
