Radiation Shielding Properties Prediction of Barite used as Small Aggregate in Mortar

Abstract

Construction materials used in the nuclear industry used to be mainly heavy materials, including lead plates, radiation-resistant heavy concrete, etc. However, these materials are either toxic after a long time of use (lead) or difficult to construct (radiation-resistant heavy concrete) and their cost is rather high. Therefore, there is a need for the manufacturing of a new kind of material with good radiation resistance, which is light, easy to use, and costs less. Barium is less toxic and more cost-effective than lead. Due to the importance of barium compounds in radiation shielding, the study of gamma radiation interactions within these compounds becomes essential, so the most important part of such a study is the experimental one, which shows the effect of the barite powder in the radiation resistance of the mortar. The research results show that the higher the thickness and percentage of barite powder, the higher is the radiation resistance.

A New Environmentally Friendly Mortar from Cement, Waste Marble and Nano Iron Slag as Radiation Shielding

“…The shielding properties of mortar could be improved by using materials of higher density than sand, where the density plays an important role in enhancing the shielding properties. For instance, barite is one of the most-studied cement blends in this context; hence, it has better attenuation features than other mortar systems [ 10 ].…”

Study of Gamma-ray Shielding of Two Different Heavy Metals and their Combination for Cs-137 and Co-60 Sources

“…Protection of biological entities from the harmful effects of radiation exposure is a fundamental requirement in the application of nuclear technology. Radiation exposure can be avoided by methods involving time, distance, and shielding, with shielding being the most important method [11][12][13][14].…”
