TL;DR
This study develops low-cost, natural clay composites reinforced with metal oxides for effective and eco-friendly radiation shielding.
Contribution
The novelty lies in using natural kaolinite reinforced with heavy metal oxides to achieve cost-effective and efficient radiation shielding materials.
Findings
Clay composites reinforced with metal oxides showed improved density, thermal stability, and radiation attenuation.

Abstract
In this work, a low-cost, natural kaolinite-based matrix reinforced with gypsum and ground marble waste was prepared with the aim of developing materials suitable for radiation shielding applications. The prepared matrix was reinforced with a fixed 30 wt% of various metal oxides, including bismuth oxide (Bi2O3), tungsten oxide (WO3), copper oxide (CuO), iron oxide (Fe2O3), and titanium oxide (TiO2). The prepared clay composites were characterized using X-ray diffraction (XRD) to determine the crystalline phases, Fourier transform infrared (FTIR) spectroscopy to study the chemical bonds, and Scanning electron microscope (SEM) to evaluate the surface morphology and the distribution of the additives within the matrix. The mechanical and thermal properties of the composites were also evaluated, along with their efficiency in attenuating gamma rays at different energies. The results showed…
