Abstract :The linear attenuation coefficients (μl) of concretes including barite fractions of 0%, 50% and 100% were measured at the gamma energies of 511, 835 and 1275 keV.The measurements have been performed using a low level gamma counting spectrometer including a 3”x3” NaI(TI) detector by ORTEC Inc., connected to a multichannel pulse height analyzer. Total mass attenuation coefficients, effective atomic numbers and effective electron numbers valuesf or concretes are calculated in the energy range from1keVto 100GeV. The values of mass attenuation coefficients used in calculations are taken from the XCOM. The results from the measurements were compared with the theoretically calculated results. The measured results of mass attenuation coefficients, effective atomic numbers and effective electron density were found to be in good agreement with the calculations.Keywords : Barite concrete, mass attenuation coefficients, effective atomic numbers, effective electron density
