Monte Carlo simulation is an important tool to obtain some parameters of a material, especially when it is impossible to perform an experiment. Radiation shielding of a material has been very important properties as the radiation started to be used in a variety of different fields. Besides using it in different fields, thus protection from its hazardous effects becomes a popular subject for researchers. For this purpose, there have been many different works done for different types of materials. Glass is an important material, and it is interesting to investigate its radiation shielding properties. Thus, in the present study, waste soda-lime-silica-based glasses (SiO2-Na2O-CaO-Bi2O3) were calculated using MCNP simulation code, and the results were compared with the XCOM calculation results.
