Study on Gamma-Ray Shielding Characteristics of Lead Oxide, Barite, and Boron Ores Using MCNP-4C Monte Carlo Code and Experimental Data

摘要

Linear and mass attenuation coefficients, effective atomic number and electron densities, mean free paths and half-value layer (HVL), and tenth-value layer (TVL) values of PbO, barite, colemanite, tincal, and ulexite were obtained for 80.1,302.9,356.0,661.7, and 1250.0 keV gamma-ray energies, respectively, using MCNP-4C and the WinXCom program and compared with available experimental data. The relative deviation (RD) values range from -11.61 % to 18.16 % and -7.83 % to 18.51 % for MCNP and WinXCom results for all samples. Only tincal boron ore showed an unexpected RD value of up to 19 %. MCNP-4C results showed better agreement with experimental data in comparison with the WinXCom program.
