The multifunctional La2O3-TiO2-Nb2O5-B2O3 glass system was evaluated for its gamma-ray and neutron shielding capabilities, focusing on its potential use as transparent containers for radioactive isotope transport. Critical shielding parameters, including linear attenuation coefficients, half-value layers, equivalent atomic numbers, and transmission factors, were analyzed using Monte Carlo simulations and other computational methods. Among the investigated samples, the 16Nb2B glass exhibited exceptional performance, with an LAC of 7.0613 cm−1 at 0.01 MeV, outperforming the 40La14B glass by 29 %. Its HVL was as low as 0.003 cm at 0.015 MeV and 1.725 cm at 0.662 MeV, marking a considerable reduction compared to steel-magnetite concrete. Moreover, the deposited energy in the air surrounding 16Nb2B was 1.18 × 10-4 MeV/g, reflecting reductions of 59.9 % and 56.1 % compared to Boron Carbide and cement-bitumen mixtures, respectively. The TF values for 16Nb2B consistently showed superior attenuation, with reductions of 6.6 % at 3.0 cm thickness and 0.662 MeV compared to steel-magnetite concrete. It can be concluded that the 16Nb2B glass not only provides outstanding optical transparency properties but also provides better radiation shielding properties, making it a promising candidate for applications in medical imaging, nuclear facilities, and radioactive material transport.
