Comparison of photon attenuation coefficients of various barite concretes and lead by MCNP code, XCOM and experimental data

► We used Monte Carlo method and MCNP-4C code for simulation. ► We simulated linear attenuation coefficients, Mfp and transmission factor for three barites and lead. ► We compared MCNP results and experimental data for various concretes in different energies. ► MCNP results showed a good agreement with experimental data.
