Investigation of the Gamma-ray Shielding Performance of CuO-CdO-Bi2O3 Bentonite Ceramics

Abstract

The purpose of this research is to identify the radiation shielding capability of ceramics adding CuO, CdO, and Bi2O3 with diverse wt (%). The chemical compositions of the raw ceramics were documented through Energy Dispersive X-ray “EDX” techniques. For aesthetic appeal and solidification, CuO has been chosen to be added to ceramic. Moreover, in the interest of increasing the radiation shielding ability, the high atomic number and density of both CdO and Bi2O3 were suggested for the raw ceramics. To obtain the morphological features of the prepared ceramic samples, a Scanning Electron Microscope, or SEM, was utilized. To verify the experimental results, the MCA value obtained from the Phy-X software was compared to the experimental value collected from the HPGe detector. At energies 0.06 MeV, 0.662 MeV, 1.173 MeV, and 1.333 MeV the linear and mass attenuation coefficients of the prepared ceramics have been measured using a high purity germanium “HPGe” detector as well as three different point sources. Moreover, the relationship between ln(I) and the thickness of the ceramics has been presented here, and the comparison between the LAC of the prepared ceramics with other materials has also been displayed. Bentonite ceramic containing CuO (15 mol %)-CdO (15 mol %)-Bi2O3 (20 mol %) with density 3.6 showed the lowest HVL, MFP, and TVL at all studied energies, yet pure Bentonite ceramic containing only CuO (50 mol %), having density 3.4, presented the greatest values. Hence, it can be concluded that the addition of CdO and Bi2O3 enhances the radiation shielding ability.

Mechanical, Morphological, Thermal and the Attenuation Properties of Heavy Mortars Doped with Nanoparticles for Gamma-Ray Shielding Applications

“…Before use, the residue was sifted and homogenized to ensure uniformity. WO 3 and Bi 2 O 3 NPs were prepared chemically by coprecipitation method [11,24] and used as fine aggregates added to the mortar composite to show the improvement of gamma-ray shielding properties, as with the addition of these particles, the density of the slurry composite increases. The ratio of the prepared mortar mixture to other studies aimed at improving the radiation shielding ability [25][26][27].…”

“…If heavy metal oxides (HMOs) are added, the density of the mortar will increase, enhancing the radiation absorption capability of the materials. Meanwhile, since these additives typically do not have a high neutron capture cross-section, their neutron shielding ability does not improve by the same amount, which is why it is useful to know the specifics of the application when designing the shielding material [11][12][13].…”

Impact of Bulk and Nano Bismuth Oxide on the Attenuation Parameters of Bentonite Barite Composites

“…Sallem et al [13] demonstrated that ball-milled calcinated bentonite has a higher gamma-ray attenuation capacity than ordinary calcinated bentonite. Al-Ghamdi et al [14] deduced that pure bentonite ceramic, granite, and marble all exhibit less radiation shielding compared to bentonite ceramic with CdO and Bi 2 O 3 . The densities of barite and bismuth are equal to 4.5 g/cm 3 and 9.75 g/cm 3 , respectively, which are considered to be high densities.…”
