In this work we investigated new different glass compositions 20PbO–20BaO–(60 − x)B2O3–xZnO (x = 0, 5, 10, 15 and 20 mol%) to study the radiation shielding capability of these glass composites. The shielding ability was measured experimentally using narrow beam method (which including HPGe detector, point sources and lead collimators). The accuracy was verified by XCOM software, the linear attenuation coefficient (LAC) of the produced glasses was ascertained using both methods. We noticed that the B40Z20 glass composite (contain 20 mol%) has the highest LAC at the four examined energies (0.060, 0.662, 1.173 and 1.333 MeV) since the LAC enhances as the ZnO content increases from 0 to 20 mol%. The based shielding parameters such as HVL and RSE or called radiation shielding efficiency were determined experimentally. The HVL reduces as the glasses' density (or, more accurately, the amount of ZnO) increases. At 0.06 MeV, the HVL have the following values: 0.041, 0.039, 0.038, 0.036 and 0.035 cm for the glasses with density of 3.582, 3.739, 3.897, 4.055 and 4.212 g/cm3 respectively. [ABSTRACT FROM AUTHOR]
