In this work, we investigated the effectiveness of bismuth borate glass doped with Dy 2 O 3 , BaO, and co-doped systems for a variety of radiation shielding uses. Within the various energy ranges (MeV), the linear attenuation coefficients (LAC) and mass attenuation coefficients (MAC) for glasses with the compositions 70B 2 O 3 + 29Bi 2 O 3 + 1Dy 2 O 3 , 20BaO + 60B 2 O 3 + 20Bi 2 O 3 , and 20BaO + 60B 2 O 3 + 19Bi 2 O 3 + 1Dy 2 O 3 were computed via the Phy-X/PSD simulation code. The acquired mass attenuation coefficients are further utilized to determine the effective atomic number (Zeff), half value layer (HVL), and mean free path (MFP) of the glasses. The co-doped glass containing BaO and Dy 2 O 3 was shown to have greater gamma-ray shielding efficacy due to higher LAC, MAC, and effective atomic number values significantly reduced HVL and MFP values. By changing the photon energy, densities, or chemical composition of the glass samples, the substantial variations in all interaction parameters were observed. A co-doped bismuth borate glass sample comprising BaO and Dy 2 O 3 exhibited superior shielding capabilities. These findings suggested that a glass sample with 20BaO + 60 B 2 O 3 + 19Bi 2 O 3 + 1Dy 2 O 3 is an effective radiation shielding material.
