The Photon Attenuation Coefficients of Building Materials Containing with Lead Carbonate (PbCO₃)

Abstract:

The total mass attenuation coefficient (μ/ρ, cm² g^-1) of gamma-ray for building materials containing with Lead Carbonate (PbCO₃) have been studied. The raw building material have cement, sand and stone in the ratio 1 : 2 : 4. The raw material was mixed with 30% of PbCO₃ to be used as the sample material. The mass attenuation coefficient of the raw material has been calculated by theoretical approach using WinXCom program for the photon energy band from 1 keV to 100 GeV. The composition of sample material was analyzed by energy dispersive X-ray fluorescence spectrometer (EDXRF). The variations of mass attenuation coefficient are shown graphically and compared with that of standard shielding concretes. It was found that the sample building material has higher value of mass attenuation coefficient than standard shielding concretes at energy zone above 2–7 keV, 90–800 keV and 5 MeV–100 GeV.
