|Abstract:||The mechanical properties and radiation attenuation competence of Tb3+ ions doped boro-germanate-aluminiophosphate (BGAP) glasses with codes Tb15, Tb20, Tb25, Tb30, Tb35, and Tb40 have been investigated. Bond compression model (B-C) and Phy-X/PSD software are used to achieve these aims. All elastic moduli were reduced with increasing the Tb2O3 content in the BGAP glasses. Values of bulk (KB-C) elastic modulus were possessed decreasing from 86.676 GPa for Tb15 glass sample to 80.205 GPa for Tb40 sample. The values of Young's (EB-C) modulus were found to decrease from 118.197 to 115.641 Gpa and Poisson's ratio (σB-C) of the BGAP glasses were reduced from 0.272 to 0.259. The highest values of linear (μ) and mass (μm) attenuation coefficients were possessed for the Tb40 glass sample. Therefore, (mass, linear)Tb40 > (mass, linear)Tb35 > (mass, linear)Tb30 > (mass, linear)Tb25 > (mass, linear)Tb20 > (mass, linear)Tb15. Half value layer parameter (T1/2) and mean free path (λ) of BGAP glasses were have a similar trend; (λ, T1/2)Tb40 < (λ, T1/2)Tb35 < (λ, T1/2)Tb30 < (λ, T1/2)Tb25 < (λ, T1/2)Tb20 < (λ, T1/2)Tb15. Exposure (EBF) and energy absorption (EABF) buildup factors have a similar attitude for all BGAP glasses. However, the minimum values of EBF and EABF were recorded for the Tb40 sample. Results confirm that Tb40 sample can be considered as superior for radiation shielding among all studied glasses. © 2022 The Author(s).|
