“…The maximum Z eff value of TBZBF series glass occurred around E = .1 MeV, whereas the maximum Z eff value of lead tellurite glass occurred between .02 and .03 MeV. When the photon energy reaches a certain value, the electrons in the inner layers of the atom leap and produce L‐ and K‐absorbing edges 36 . The Z eff value of leaded tellurite glass was higher than that of lead‐free tellurite glass at E < .04 MeV.…”

“…When the photon energy reaches a certain value, the electrons in the inner layers of the atom leap and produce L-and K-absorbing edges. 36 The Z eff value of leaded tellurite glass was higher than that of lead-free tellurite glass at E < .04 MeV. It was because the photoelectric effect of the L-edge absorption region of Pb was greater than that of Bi in the low-energy.…”

This paper studied the radiation shielding properties of new lead‐free telluride glass with different BaF2 content. The 65TeO2–15Bi2O3–(20 − x)ZnO–xBaF2 glass systems (where x = 1, 3, 5, 7, 9 mol%) were tested through the X‐ray diffraction, ultraviolet–visible spectrophotometer, and differential scanning calorimetry. The glass system exhibited good thermal stability and a uniform surface without surface crystallization. The linear attenuation coefficient of the TBZBF series glass was tested using five different gamma radiation sources (241Am, 133Ba, 57Co, 137Cs, and 60Co). They were calculated to the mass attenuation coefficient, half‐value layer, mean free path, and effective atomic number through numerical simulations with XCOM software. The maximum mass attenuation coefficient for TBZBF‐9 was calculated to be 5.3577 cm2/g. Comparisons were made between this glass system and other tellurite and leaded glasses reported in the literature. The glass system exhibited superior radiation shielding capability compared to leaded tellurite glass under the same testing conditions. The gamma radiation shielding capacity increased with BaF2 content in the glass system. These results show that TBZBF‐9 exhibited the best gamma radiation shielding effectiveness while maintaining glass transparency.
