The effect of using Nano iron oxide in radiological shielding

Abstract

In this study, some attenuation parameters of gamma shields were studied. This shields consisting of composite materials of Unsaturated polyester as a base material and Nano iron oxide (Fe2O3) and, micro iron (Fe) as reinforcement materials at different percentages (1, 3,5,7and 9)wt%, and with different thickness (1, 1.5, 2, 2.5, 3, 3.5and 4) cm. The results showed that the use of nanoparticles is better than the microparticales in the field of radiation shielding. It has been shown that the values of attenuation parameters of gamma it bitter in the case of nanoparticles than case of the use of micro material.

Radiation shielding effectiveness, structural, and mechanical properties of HDPE/B4C composites reinforced with Fe2O3-Al2O3-Al-Fe fillers

“…Iron and/or iron oxide as fillers incorporated into various composites for radiation shielding were investigated in different studies. The results indicated that the attenuation capacity of the prepared composites was enhanced compared with the traditional shielding materials [2,[48][49][50][51][52]. Aluminum and/or aluminum oxide have been investigated as fillers to improve the mechanical properties and radiation shielding effectiveness for different matrix composites.…”
