Title: High transparency La2O3-CaO-B2O3-SiO2 glass for diagnosis x-rays shielding material application
Abstract: The La2O3 added in (80-x) B2O3:10SiO2:10 CaO:xLa2O3 glass (where x = 10, 15, 20, 25 and 30 mol%) were prepared by melt-quenching technique have been investigated for x-ray shielding, physical and optical properties. The density of the glass samples found to increase which increasing La2O3 concentrations. The transmission spectra result demonstrated that the glass samples had high transparency similar with commercial window, corresponding to high visibility in the visible region as already observed. The mass attenuation coefficient (µm) were increased with the decreasing of kilovoltage peak (kVp) of an x-ray instrument, and increased with the increasing of La2O3 concentration. The half value layer (HVL) and ten value layer (TVL) of glass samples trend to decrease when the kVp of an x-ray instrument decrease and La2O3 concentrations increase. The trend of lead equivalent increase which Ln2O3 concentrations and the kVp of an x-ray instrument increasing. All results indicating the potential of the prepared glasses as Pb-free and high visibility for diagnostic x-ray shielding material.
