Abstract

The purpose of this study is to evaluate the X-ray radiation shielding properties of rice flour doped with barium sulfate (BaSO₄) at concentrations of 0%, 1%, 5%, 10%, 15%, and 20% by weight. The experimental technique involved X-ray exposure at 50–120 kVp, 100 mA, and 2 seconds. Results indicate that increasing BaSO₄ content increases the linear attenuation coefficient (LAC), while the half value layer (HVL), tenth-value layer (TVL), and mean free path (MFP) decrease. At 20% BaSO₄, the HVL values of the doped rice flour are comparable to X-ray windows and thyroid shields and superior to commercial windows, red bricks, and concrete. Therefore, rice flour doped with BaSO₄ has potential as an alternative radiation shielding material in diagnostic regions in the future.
