Abstract: Radiation shielding is considered as a highly sensitive issue in the department of medical physics. Proper utilization of material in radiation shielding can be effective in terms of economy, durability and safety measure. Concrete is nowadays extensively used as a material for radiation shielding. The coarse aggregate of concrete plays an important role in concrete density where the density is related to the radiation attenuation. In this research, the feasible study has conducted of using the recycled coarse aggregate in radiation shielding. The focus of this paper is to introduce a possible better alternative of fresh aggregate to make the concrete shielding. Two types of recycled aggregates were taken; recycled stone aggregate (RCA) and recycled brick aggregate (RBA). Aggregate material properties were found out at the beginning of the research. As the Brachytherapy unit used in the research, the Cobalt-60 (Co-60) was selected as a source of photon energy. Then the HVL and TVL were measured based on the attenuation of radiation. The study shows that the use of recycled concrete in the radiation shielding is optimistic.
