A study of x-ray radiation shielding properties of bricks contained barium sulfate

Abstract

© 2020 Author(s). The x-ray room wall thickness is usually around 20-25 centimeters, using clay bricks and cement as material to create x-ray protective barrier for staffs and patients. Gain more space to provide a wall of X-ray room. In this study, the x-ray radiation shielding properties of bricks contained barium sulfate (BaSO4) was determined at the proportion of barium sulfate and clay about 0, 5, 10, 15 and 20% in parameters radiation dose between 50-120 kilovoltage (kVp) 40 milliamperes seconds (mAs) for radiation shielding to employees and members of the public. The results revealed that the Mass attenuation coefficient value (μm) are increased when the proportion of barium sulfate is higher. Nevertheless, they are decreased when radiation dose is higher. The half-value layer (HVL) are decreased when barium sulfate increase. The HVL of barium sulfate brick less than when compared with commercial brick and concrete. The results indicating the potential of the prepared barium sulfate brick as lead free for x-ray room.
