Abstract
The radiation attenuation parameters such as radiation mass attenuation coefficients (MAC), half value layer (HVL), mean free path (mfp) of boron carbide (B4C) have been calculated at radiological x-ray energies using MCNPX (version 2.6.0) general purpose Monte Carlo code. The results obtained from MCNPX have been compared with standard XCOM data. Moreover, the obtained mass attenuation coefficient results have been compared with ordinary concrete. Furthermore, standard deviation rates between MCNPX and XCOM were also calculated by statistical methods and a good agreement was obtained. The results showed that, present investigation can be useful for evaluation of shielding features of B4C. It can be concluded that modeled standard geometry for present investigation can be used for shielding assessment of B4C at radiological energy range.
