Determination of Mass Attenuation Coefficients of Different Types of Concretes using Monte Carlo Method

Abstract

Shielding and radiation protection are important subjects for various areas ranging from medical and agricultural sectors to consumer products. As such, it is a branch of science and technology, wherein radiation exposure to the receptor is reduced by shielding. In this study mass attenuation coefficients, µ/ρ for some concrete with potential applications in nuclear technology and radiation protection as well as medical physics have been calculated using MCNPX (version 2.4.0) at different photon energy levels. Appreciable variations are noted for mass attenuation coefficients of the concrete by the changes in the photon energy. The MCNPX results are compared with available experimental investigations and theoretical XCOM results, and good agreement is being observed. Present study indicates that MCNPX simulation method is suitable method to be used as an alternative method for the investigation of gamma interaction and would very useful materials for different energies for radiation dosimetry, medical and nuclear technology.
