The investigation of the radiation shielding features of boro-tellurite glasses containing bismuth and titanium via FLUKA code

Abstract The gamma radiation shielding features of four different boro-tellurite glasses with chemical composition x TiO 2 - y Bi 2 O 3 - z B 2 O 3 -(100- x - y - z ) TeO 2 ( x = 5, 10 mol%, y = 10,20, 25, and 30 mol% and z = 20 and 30 mol%) were examined using FLUKA Monte Carlo code. The simulations were run for photon energies of 245, 356, 511, 662, 964, 1173, and 1332 keV emitted by 152 Eu, 133 Ba, 22 Na, 137 Cs, and 60 Co. The obtained results show that the Bi 2 O 3 addition increased the mass attenuation coefficient (MAC) ranges from 0.2559 to 0.3584 cm 2 g −1 , 0.1454 to 0.1869 cm 2 g −1 , 0.0992 to 0.1167 cm 2 g −1 , 0.0803 to 0.0902 cm 2 g −1 , 0.0620 to 0.0667 cm 2 g −1 , 0.0549 to 0.0581 cm 2 g −1 , and 0.0511 to 0.0535 cm 2 g −1 for 245, 356, 511, 662, 964, 1173, and 1332 keV, respectively. The photon attenuation parameters, such as half-value layer (HVL), ten-value layer (TVL), and mean free path (MFP), were also studied. The results showed that Bi 2 O 3 substitution positively impacts the produced glasses’ photon attenuation abilities.
