Evaluation the Shielding Properties of Various Water Equivalent Materials Using Different Calculation Methods and Monte Carlo

“…For effective neutron radiation shielding, the material structure should consist of hydrogen-rich or low atomic number element combinations [10]. One of the fundamental quantities used for predicting neutron shielding is the fast neutron effective removal crosssection (𝛴𝑅) [11]. This empirical cross-section has been derived for hydrogenous systems and utilized in reactor shielding calculation methods.…”

“…𝛴𝑅 is known as a characteristic of materials. To predict the ΣR of any material, a dataset of elemental mass removal cross-sections (ΣR/ρ) is used [11]. This research involved computing the LAC, MAC, HVL, and MFP measurements for different substances like ABS, presage, RMI457, RW3, SW557, epoxy, A150, Rhizophora spp.…”

“…These values were obtained using empirical formulas from equations 4, 5, and 6, as well as MCNP5 Monte Carlo simulation, MRCsC, and Phy-X/PSD software programs. In the study conducted by Hila et al[11], they numerically generated fast neutron mass removal cross-sections (ΣR/ρ, cm 2 /g) based on ENDF/B-VIII.0 using a sliced spherical shell Monte Carlo model under different neutron source spectra. Using the generated ΣR/ρ values in this study, ΣR values for various materials were determined.…”
