Study on radiation shielding properties of glass samples doped with holmium

Abstract

© 2020 Author(s). Nowadays, radiation has been utilized and importance in our daily life. Importantly, the radiation to achieve most effective goal and prevent radiation hazards for safe and accuracy. The principle of radiation protection are called "As Low As Reasonably Achievable"make sure staff follow these 3 major safety principles consisting of distance, time, and shielding. The radiation shielding material are common used as lead in manufacturing process lead are high toxicity. Therefore, the researcher is interested in using other elements to replace lead. This study used by glass structure formula (60-x) P2O5: 10Al2O3: 20Na2O: 10Gd2O3: xHo2O3 where x = 0.00, 0.05, 0.10, 0.50, 1.00 and 3.00mol%. The result shows that the linear attenuation coefficient (μm) was increased when Ho2O3 concentration were increased. The mass attenuation coefficient (μ) was increased when Ho2O3 concentration were increased. The half value layer (HVL) was decreased when Ho2O3 concentration were increased. The results in this study in glass formula 57P2O5: 10Al2O3: 20Na2O: 10Gd2O3: 3Ho2O3 has high quality in the X-ray shielding range of 50-120 kVp compared to the concentration of 0.00,0.0,0., 0.50 and 1.00mol% respectively. The HVL of glass samples doped with Holmium compared with commercial windows, red brick, concrete, X-ray windows, and the results show that 0.50, 1.00 and 3.00 % mole the HVL less than X-ray glass. This study shows the properties of Ho2O3 in X-ray shielding and highly practical potentials in the environmental friendly radiation shielding materials without an additional of lead.
