Enhancement of Ceramics Based Red-Clay by Bulk and Nano Metal Oxides for Photon Shielding Features

Abstract

We prepared red clays by introducing different percentages of PbO, Bi2O3, and CdO. In order to understand how the introduction of these oxides into red clay influences its attenuation ability, the mass attenuation coefficient of the clays was experimentally measured in a lab using an HPGe detector. The theoretical shielding capability of the material present was obtained using XCOM to verify the accuracy of the experimental results. We found that the experimental and theoretical values agree to a very high degree of precision. The effective atomic number (Zeff) of pure red clay, and red clay with the three metal oxides was determined. The pure red clay had the lowest Zeff of the tested samples, which means that introducing any of these three oxides into the clay will greatly enhance its Zeff, and consequently its attenuation capability. Additionally, the Zeff for red clay with 10 wt% CdO is lower than the Zeff of red clay with 10 wt% Bi2O3 and PbO. We also prepared red clay using 10 wt% CdO nanoparticles and compared its attenuation ability with the red clay prepared with 10 wt% PbO, Bi2O3, and CdO microparticles. We found that the MAC of the red clay with 10 wt% nano-CdO was higher than the MAC of the clay with microparticle samples. Accordingly, nanoparticles could be a useful way to enhance the shielding ability of current radiation shielding materials.

Preparation of Mortar with Fe2O3 Nanoparticles for Radiation Shielding Application

“…The LAC for MI-10 (for example) at 0.06 MeV is 0.598 cm −1 , while it is only 0.1301 cm −1 at 1.333 MeV. The LAC values at low and high energies for the reference mortar and other mortar samples with Fe 2 O 3 nanoparticles have the same trend as the LAC reported in other studies and for different materials [34][35][36].…”

The Influence of Bi2O3 Nanoparticle Content on the γ-ray Interaction Parameters of Silicon Rubber

“…The experimental values of the LAC for SR and the micro filler were compared to the results obtained from the XCOM software [32,33]. The relative deviation between the two results is calculated by the following:…”

Investigation of red clay and waste glass composite bricks for ionizing radiation shielding

“…Materials like lead, steel, and concrete are the most commonly used shields against ionizing radiation [ 5 ]. Ongoing research explores nanomaterials and advanced composites for enhanced shielding properties [ 6 ]. These materials aim to provide improved protection while addressing the limitations associated with traditional shielding materials.…”
