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.
