In the present work, the efficacy of waste glass as fillers in concrete for gamma-ray shielding has been studied. Glass fillers of 0, 15, 30, 45, and 60% concentrations have been incorporated into the concrete mixture. The attenuation measurements were performed using gamma spectrometer with NaI(Tl) detector at 511, 662, 1173, and 1332 keV gamma energies. Gamma-ray shielding parameters, such as the mass attenuation coefficient (μ/ρ), are determined for all filler concentrations. The mass attenuation coefficient of the prepared samples was found to be varied from 0.081 to 0.088, 0.071 to 0.088, 0.05 to 0.058, and 0.05 to 0.055 (cm2 per g) for 511, 662, 1173, and 1332 keV gamma energies, respectively. It was observed that experimentally determined (μ/ρ) values were in very good agreement with theoretical values calculated from EDAX data. Furthermore, it was observed that (μ/ρ) showed an increasing trend with an increase in filler concentration, which is attributed to the increase in the shielding property of the material. Therefore, the glass-concrete composite can be accustomed to reduce the intensity of gamma radiation.
在本工作中，研究了废玻璃作为混凝土中伽马射线屏蔽用填料的功效。将浓度为 0、15、30、45 和 60%的玻璃填料掺入混凝土混合物中。使用带有 NaI(Tl)探测器的伽马光谱仪在 511、662、1173 和 1332 keV 的伽马能下进行衰减测量。确定了所有填料浓度的伽马射线屏蔽参数，如质量衰减系数(μ/ρ)。发现制备样品的质量衰减系数在 511、662、1173 和 1332 keV 伽马能下分别为 0.081 至 0.088、0.071 至 0.088、0.05 至 0.058 和 0.05 至 0.055(cm2/g)。实验测定的(μ/ρ)值与从 EDAX 数据计算得出的理论值非常吻合。此外，观察到(μ/ρ)随填料浓度的增加呈上升趋势，这归因于材料屏蔽性能的提高。因此，玻璃-混凝土复合材料可以用来降低伽马辐射的强度。
