Abstract

Abstract:

In this work, linear and mass attenuation coefficients, half and tenth-value layers, effective atomic number and electron density of different types of concretes were determined at 316.51, 468.07, 511, 662, 1173 and 1332 keV using MCNP-4C code and WinXCom programs. The MCNP-4C and WinXCom results agreed well with each other, with differences of <±1.9%. The results agreed with available experimental data, too, with differences of <±6%. The MCNP-4C results showed better agreement with the experimental data than the WinXCom results. Also, it was found that the effective electron density of studied concretes varies in the range of (2.83–3.2) × 1023 electron/g.
