Abstract
The mass attenuation coefficients, linear attenuation coefficients and tenth value layer of seven types of concretes having density (2.3–5.11gcm−3) have been simulated by Monte Carlo simulation techniques at photon energies 1.5, 2, 3, 4, 5 and 6MeV. Numerical simulation results have been compared with experimental and XCOM photon cross section database and showed a good agreement. Linear attenuation coefficient and tenth value layer of the concretes were found chemical composition, density and photon energy dependent. The tenth value layer of the concretes decrease with increase iron content and increase with increase in photon energy. The linear attenuation coefficients values of the concretes increase with density and decrease with photon energy. Monte Carlo simulation, calculated and experimental results show that the ordinary concrete having lowest iron content (0.63%) have minimum linear attenuation coefficient.
