Abstract: This work focuses on the preparation of borotellurite glasses doped with BaO, Bi2O3, and Er2O3, and the investigation of their radiation attenuation parameters. A narrow beam experiment was conducted to assess the attenuation factors of the glasses. A positive relationship was observed between the linear attenuation coefficient and the concentration of Er2O3. The linear attenuation coefficient for the Er2O3-free glass at 0.059 MeV is 19.729 cm-?, while for the sample with 3 mol % Er2O3, it is 26.113 cm-?. At 0.662 MeV, the linear attenuation coefficient for the Er2O3-free glass and the glass with 3 mol % Er2O3 are 0.426 cm-? and 0.461 cm-?, respectively. The mean free path of the glasses exhibited an inverse relationship with increasing Er2O3 content. For the glass containing 1 mol % Er2O3, the mean free path values are 0.046 cm, 2.285 cm, and 3.556 cm at 0.059 MeV, 0.662 MeV, and 1.173 MeV, respectively. The half-value layer was calculated, and the results indicated that the addition of Er2O3 causes a decrease in the half-value layer, suggesting an enhancement in the radiation attenuation performance of the prepared glasses as more Er2O3 is added.
