The purpose of this study is to evaluate the reliability of the Monte Carlo simulation programs GATE and MCNP6 for simulating the performance of radiation shielding devices. Medical diagnostic tube voltages of 70, 90, 110, and 130 kVp were used for a comparative analysis of the shielding rates for the devices on the market. As a result of the simulations, we obtained a maximum error of 2.81% for a tube voltage of 70 kVp and and a lead(Pb) the closes of 0.25 mm, Pb, and a minimum error of 0.04% for a those voltage of 110 kVp and 0.35 mm. The average error was 1.05%, which is small enough to confirm that the graphs from the two programs were quite similar considering the statistical error and code differences. Hence, we conclude that the GATE and the MCNP6 programs show consistent results and can be safely employed as simulation tools for radiation shielding devices.
