“…We use the method of nitrogen gas adsorption at 77 K to determine the surface properties using traditional (Brunauer‐Emmett‐Teller) method. Gamma ray attenuation method [19, 20] is used to determine the effective density of the different samples. Our objectives are to investigate the means how two materials having different morphologies are synthesized in a common route and the influence of these phenomena on the specific surface area and density of the composites.…”

In the present work, we investigate the surface, and bulk structural properties of composite cupric oxide ribbons, and zinc oxide particles. The composites are synthesized using the technique of solution combustion. Crystallographic phases are confirmed using the x‐ray diffraction technique and proved the formation of monoclinic cupric oxide and hexagonal zinc oxide crystallites. Scanning electron microscope and high‐resolution transmission electron microscope are used to examine the morphology of the prepared materials. Composite mixtures of raw particles cupric oxide and zinc oxide are used as benchmark morphologically‐alike composite materials. The specific surface area values of the studied materials are investigated using nitrogen gas adsorption at 77 K while the spectroscopic gamma ray attenuation is used to determine the effective density of the different samples. Zinc oxide particles are dispersed on cupric oxide ribbons and cause nonlinear dependence of the specific surface area and density on the composition ratio due to the physical contact between particles, especially at the voids and the nodes of the fibrous ribbons network.

In this study, pure silicone rubber and iron ore concentrate added silicone rubber materials were performed against Cs-137 gamma source. Cs-137 is accepted intermediate energy level gamma source in nuclear technology because of its energy peak at 0.662 MeV. Up to 67 wt. % iron ore concentrate added into silicone rubber materials were used in the experiments. Linear attenuation curves were carried out for the studied samples against Cs-137 gamma energy. Increasing iron ore ratio in the materials caused the higher radiation shielding performance for Cs-137 gamma energy. In addition, increasing iron ore ratio decrease the total volume air bubbles in the samples. Decreasing air bubbles in the samples has contributed to gamma ray shielding. 0.5 mmPbE and 1 mmPbE Lead equivalent (PbE) values were determined for the samples. 0.5mmPbE standard has been provided by using 2.83 mm thick of 67 wt. % iron ore concentrate imbedded silicone rubber at 0.662 MeV gamma energy. In conclusion, iron ore concentrate imbedded silicone rubber materials are among the promising economic radiation shielding materials which could be alternative to lead.

Radiation safety and protection is a subject of major concern for all communities because of the biological damage caused by different radiation sources. Therefore, the purpose of this study is aimed to synthesize two different thin films from a newly synthesized N-Al2O3@Pb(II)-2,4-DiNA nanocomposite which was prepared by the direct chemical coupling of nano-aluminum oxide (N-Al2O3) with Pb(II)-2,4-dinitroaniline complex. The synthesized materials were characterized by FT-IR, thermogravimetric analysis (TGA), scanning electron microscope SEM, and elemental composition by energy-dispersive X-ray (EDX). The two thin films were assembled by the encapsulation of N-Al2O3@Pb(II)-2,4-DiNAnanocompositeinto hydrolyzed polyurethane and hydrolyzed polyvinyl chloride. Electron spin resonance (ESR) measurements have been used to investigate the newly prepared nanocomposite and thin films before and after gamma irradiation. Gamma spectroscopy, Phy-X software, and SRIM (stopping and range of ions in matter) Monte Carlo simulation code are aimed to apply and investigate radiation shielding efficiency of films for gamma/x-ray, protons, alpha, and thermal neutrons. The gamma shielding characteristics, mass stopping power (MSP), and range for both proton (H-ions) and alpha (He-ions) were also calculated. In addition, the SRIM code’s subroutine TRIM was used to predict the damage production and atomic displacements per atom (dpa) caused by the interaction of high-energy H-ions (proton) and He-ions (alpha) with the studied samples. The data obtained the good radiation shielding effect of the prepared thin films and their possible use as radiation shielding materials for X-rays and low gamma energy.
