Determination of Mass Attenuation Coefficients for Some Cement Types Used As Building Materials in Turkey

This work presents experimental and theoretical mass attenuation coefficient values of six cement types used in building construction in Turkey. The experimental mass attenuation coefficients were measured at 14 different gamma ray energies from 81 to 1332.5 keV by using 109Cd, 57Co, 133Ba, 54Mn, 137Cs, 60Co and 22Na radioactive sources. Measurements were carried out by using gamma spectrometry with a high purity Ge detector with a resolution of 1.9 keV at the 1332.5 keV. The chemical compositions of cement types were analyzed using EDXRF system. Taking into account the elemental compositions of cement types, theoretical mass attenuation coefficients were calculated using XCOM programme
