Comparison and Evaluation of Monte Carlo Simulation Codes for Medical Radiation Shielding of Metal 3D-printed Materials

초록

The purpose of this study is to evaluate the shielding performance of 3D-printed metal materials against medical radiation. Three-dimensioned printed metal materials such as titanium, zirconium, stainless 316L, molybdenum, palladium, tantalum were selected, and a radiation penetration rate of 5% was observed with tube voltages ranging from 60 kVp to 150 kVp. The consistency was verified by comparing the GATE as a dedicated code with MCNP as a general code based on Monte Carlo simulation. The error rate of each material tended to decrease as the tube voltage was increased. The average error of all materials was confirmed to be 0.55%, given the difference in stochastic statistical fluctuations. Thus data can be used in thickness selection when manufacturing equipment for radiation shielding and as a basis for various future studies. © 2021 The Korean Physical Society. All rights reserved.
