Abstract The present study consists of two batches the first one composed of bentonite/ gypsum with bismuth oxide (Bi2O3) as filler with different concentrations composites. The second batch consists of bentonite/ barite with bismuth oxide (Bi2O3) as filler with different concentrations composites Due to the present industrial word, the risks radioactivity is notably increasing. Thus, an appropriate shielding material needs to be designed to protect humans and environment against radiation. In view of this, the present study aims to design new composites of the main matrix of bentonite-gypsum with low cost, abundant, and natural matrix. This main matrix was intercalated in various amounts with micro-and Nanosized of bismuth oxide (Bi2O3) as the filler. |
