Iron (III) Oxide-Based Ceramic Material for Radiation Shielding

Abstract

We developed a new ceramic from raw material mainly composed of iron (III) oxide. The measured attenuation coefficient of the ceramic for high-energy gamma rays was in the range 0.268–0.355, which is approximately 40% of that of lead and twice that of concrete. The measured penetrating dose of the ceramic is half of that of concrete. Thus, the novel ceramic material named RASHIX may serve as a novel ceramic alternative for the wide variety of radiation shielding materials used in construction.

Towards better understanding of structural, physical and radiation attenuation properties of the granites in Aegean region of Turkey: İzmir and Kütahya Provinces

“…This high Fe 2 O 3 additive ratio also resulted in a significant rise in the density of samples 4 and 5, thus contributing to the sample number 5's highest density value (i.e., 2.7184±0.0008 g cm −3 ). Similar findings have been reported in the literature, where varying the Fe 2 O 3 level had a noticeable influence on material density as well as radiation shielding properties [44,45]. One of the most important parameters attributed to the materials used in radiation fields is the half value thickness.…”

Shielding Ability of a Novel Iron Ceramic Material for Gamma-Rays

“…The ceramic products used in this study were produced by the previously reported procedure, whose main ingredient is iron (III) oxide. 6) A brief description of how to make it is given below. A powder containing 99% iron oxide was fabricated into specimens by pressing gently into an iron mold, and then it was pushed and hardened with 3 MPa/cm 2 .…”

“…Other details related to sample preparation are referred to our previous report. 6) To investigate the shielding ability, plate-like samples of 1 cm in thickness and 10 cm in height and width were prepared, and the required number of plates were piled on top of each other. Controls for the shielding ability evaluation experiments were lead and iron plates of the same shape and a piece of concrete of 5 cm in thickness, 10 cm in height and width (Fig.…”

“…5) We developed a ceramic made with iron (III) oxide (Fe 2 O 3 ) expected to be a novel toxicfree shielding material named RASHIX. 6) This material is already in practical use, though chemical analysis of its properties is still needed. In this study, the radiation shielding performance of this material against gamma-rays was evaluated in detail, and its potential as a radiation shielding material was examined.…”

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.…”
