A Study on Radiation Shielding Ability of Composite Materials Using Monte Carlo Simulation

초록

In this study, Monte Carlo n-patricle transport code (MCNP) simulation was used to derive equations that can be applied to all materials to calculate radiation shielding ability. The linear attenuation coefficient term, which ignores the interface in the composite material, was easily obtained by a well-known equation and was used in the simulation for more accurate calculation. The linear attenuation coefficients calculated by simulation show the same tendency in all materials regardless of y-ray energy. The value calculated by this tendency is considered to be the maximum value of the linear attenuation coefficient of composite material made of two materials.
