Abstract:

In this work, the glass formula (70-x)P2O5: 15NaF: 5ZnF2: 15AlF3: xBaO where x is 0, 5, 10, 15 mol% were manufactured by the conventional melt-quenching technique at 1200 °C in 3 hours for photon shielding application. The effect of glasses was examined on the physical, gamma ray and x-ray shielding properties. The results revealed that the density was increased with increasing of BaO concentrations. The glass systems were calculated by using the experiment set up for estimating the radiation shielding properties in the content of mass attenuation coefficients (μm), effective atomic number (Zeff), and effective electron density (Neff), which were increased when concentrations of BaO increased, while the half value layer (HVL) was decreased. For result of using the x-ray source, the linear attenuation (μ) was increased with an accrue in BaO concentration. The HVL was decreased when concentrations of BaO increased. The HVL values of glass samples at 15 mol% has better shielding behavior than the standard materials at 120 kVp. The BaO glass systems can be candidate for radiation shielding materials in the future.
