Investigation of mass attenuation coefficients of water, concrete and bakelite at different energies using the FLUKA Monte Carlo code

Determination of mass attenuation coefficient for some polymers using Monte Carlo simulation

“…The µ/ρ values for water using MCNP-4C were in very good agreement with FLUKA[23], XCOM and experiment[15][16][17]. Also, insignificant variation in µ/ρ values for the polymers with carbon content was observed.…”

“…In the present work, we have calculated mass attenuation coefficients for some polymers (see in Table 1) using simulation geometry method with MCNP-4C code with the objective to test the simulation geometry method to provide the radiation safety. Firstly, mass attenuation coefficients were calculated for the polymers, and results were compared with XCOM program and experimental data from literature [15][16][17][18][19][20][21][22].The mass attenuation coefficients for water were determined, and compared with experimental data, theoretical XCOM [12] and FLUKA simulation reported by Demir et al [23]. At present the experimental values of mass attenuation coefficient for very few polymers are available for limited photon energies.…”

“…However, at intermediate and high energies the MCNPX results were found in good agreement with theoretical XCOM data, experiment results and other simulation results. The µ/ρ values for Bakelite and concrete using MCNPX and Fluka (Demir et al, 2013) were also found comparable. It can be concluded that mass attenuation coefficients for compound or composite materials having low-as well as high-atomic number elements for low-to high-energy of photons are found comparable with the experiment and GEANT-4, MCNP and Fluka simulation codes (Vishwanath P. Singh et al, 2014).…”

A theoretical way to determine gamma-ray mass attenuation coefficients of materials

“…In addition, these materials were chosen so that they were the same as those in the literature and it was possible to compare directly the results from FLUKA with them [13][14][15][16][17]. The effect of the number of incident gamma photons on the materials was also investigated in the introduced study, unlike in the previous ones.…”
