Abstract :

This work analyzes a glass sample with the chemical formula (65-x)B2O3-15TeO2-15Bi2O3- 5La2O3-xAg2O, where x equals 0, 0.5, 1, 1.5, and 2 mol%. The density of the glass samples increased from 3.15 to 3.2 g/cm³, and the molar volume also increased from 49.326 to 49.56 cm3 /mole, with increasing molar concentration of Ag2O. The linear attenuation coefficients were calculated for gamma photons over the energy range 015MeV – 15 MeV. With these linear attenuation coefficient values, further attenuation parameters, i.e., half value layer (HVL), mass attenuation coefficient (MAC), and effective atomic number (Zeff), were then calculated. The measured values of these attenuation parameters were also compared with the theoretical values obtained through the online software Py-MLBUF. The findings show that the linear attenuation coefficient (LAC) increases with increasing sample density and increasing proportions of Ag2O. The prepared glasses indicate a stronger shielding ability among the materials investigated than the usual glass and concrete samples do. This study highlights the potential of these glass compositions as effective materials for gamma radiation shielding.
