摘要

In this paper, the gamma mass attenuation coefficient is investigated experimentally and theoretically for samples of building materials available in Iraq with different origins. Mass attenuation coefficients were measured using shielded NaI (Tl) spectrometer detector. Samples were irradiated by gamma-rays emitted from point sources of ~(241)Am, ~(133)Ba, ~(137)Cs and ~(60)Co and. The measured results were compared with the theoretical calculations of XCOM and Geant4 codes, and agreements have been observed especially for Monte Carlo simulations code Geant4.
