In the present era, due to various industrial developments, there is a need to use different applications of nuclear energy. But the leading challenge is the management of nuclear waste, which emits dangerous rays such as gamma rays. This research aim is to create a layer to be used as a protective coating against radiation in low-level waste landfills. In this paper, bentonite is used as a base material and red mud as an additive. Also, to determine the linear attenuation coefficient (), a combination of bentonite with 0, 15, 30, and 45% red mud with bentonite was used. To perform a linear attenuation coefficient test, the NaI (Tl) detector and the source of Co ⁶⁰ were used at two energy levels of 1173 and 1332 keV. The results of laboratory tests show that the addition of red mud has improved the parameter of the linear attenuation coefficient of radiation at both energy levels so that the energy level of 1173 keV and 1332 keV with the addition of 45% red mud has improved by 16 and 12%, respectively.

在当今时代，由于各种工业发展，需要利用核能的不同应用。但主要的挑战是核废料的管理，它会发出伽马射线等危险射线。这项研究的目的是创造一层用作低放垃圾填埋场辐射防护涂层。本文以膨润土为基材，赤泥为添加剂。此外，为了确定线性衰减系数 ()，使用了膨润土与 0、15、30 和 45% 赤泥与膨润土的组合。为了执行线性衰减系数测试，NaI (Tl) 检测器和Co ⁶⁰源在 1173 和 1332 keV 两个能级下使用。室内试验结果表明，赤泥的加入提高了两个能级的辐射线性衰减系数参数，使1173 keV和1332 keV的能级在加入45%赤泥后提高了16和 12%，分别为。
