  In this study we have reported the borate-based glasses in the form of $4(75
- x)B-2O-3 - xBi_2O_3 - 10Na_2O - 10CaO - 5Al_2O_3$ ($0 \le x \le 25$ mol%) for
gamma-ray and neutron shielding applications, and for this purpose mass
attenuation coefficients of these glasses have been investigated using Geant4
code and XCOM program in the energy range between 1 keV and 10 MeV. A good
agreement between the simulation results and computed values was observed. The
obtained values were then used to calculate the other related shielding
parameters such as half value layer (HVL), mean free path (MFP) and effective
atomic numbers ($Z_{\rm eff}$). Exposure buildup factors of the glasses were
also evaluated by using the geometrical progression (G-P) method. Additionally,
neutron effective removal cross-sections of each selected glass have been
computed. The results indicate that the Bi2O3 content in the glass sample
affects the radiation shielding properties. It can be concluded that the glass
coded as F offers superior gamma-ray shielding properties, while the glass
coded as D offers better neutron shielding features among the other samples.
