طينة التدريع الإشعاعي باستخدام رمل الباريت و الهيماتيت

Abstract EN

This study aims to find the best mixture of Mortar (cement + sand + water) using local natural materials, and choose the best mix in terms of radiation and technical properties, so that they can be used for radiation shielding, especially in shielding facilities which are not designed primarily to contain radiation.

In this study samples of mortar with different mixing ratios were prepared using three different types of sands: Barite, Hematite and Normal sand.

We focused in this study on the effect of increasing sand proportion in each sample on the linear attenuation coefficient for x-rays with energy 80,100,110,120keV and gamma- photons with energy 662keV, using trans-rays method and using X-COM to calculate these coefficient.

Results showed that the addition of Barite and Hematite sands to concrete mix increases the density of samples compared with Normal sand samples, and the linear attenuation coefficient values increases with increase of samples density and decreases with the increase of X-rays energy (and gamma photons energy) and Barite samples attenuate more than Hematite and Normal sand samples.
