Gamma radiation shielding behaviour of B2O3-MnO2-PbO glasses with low density using a Monte Carlo method

B2O3-MnO2-PbO glass formations with various B2O3 and PbO molar compositions were investigated for determining shielding properties. FLUKA codes was employed to compute mass attenuation coefficients (μ_m) for the glasses at the 133Ba (0.356 MeV), 137Cs (0.662 MeV) and 60Co (1.173 and 1.330 MeV) photon peaks. The simulated μ_m were compared to Phy-X/PSD and WinXCOM programs. To verify the present code, the computed μ_ms were cross-checked with MNCPX and the XCOM database for the test glass system. The largest deviation between FLUKA and MNCPX were found to be 1.83%, whereas the deviation between the FLUKA and XCOM was 0.37%. Moreover, μ_m findings from FLUKA showed a satisfactory agreement with XCOM and Phy-X/PSD with differences below 1% for the primarily studied glasses (BMLs). It is concluded that BML1 has better attenuation behaviour than those with lower amounts of PbO in terms of μ_m and Zeff for energies below 1 MeV.
