Photon attenuation coefficients of concrete including marble aggregates

The linear attenuation coefficients (μ, cm−1) for concrete having marble aggregates in different concentrations have been investigated. The marble concentrations investigated in the work were 0%, 5%, 10%, 15%, 20% and 25% in concrete. The measurements were performed using a gamma spectrometer that contains a NaI(Tl) detector and Multi-Channel-Analyser (MCA) connected to a PC. Three different gamma rays energies have been used at 662, 1173 and 1332 keV from 137Cs and 60Co sources respectively. The measured results were compared with the calculation obtained using computer code of XCOM for 1 keV–1 GeV gamma energies.
