Ionizing radiation sources are widely used in numerous fields such as health and energy sectors, nuclear industry, aviation and space applications. As a result, employees are exposed to radiation. Radiation shields have mostly been made of lead so far. Although lead is a proper shield for neutron radiation, it has many harmful effects. Recent studies have focused on the development of neutron radiation shielding materials with high attenuation efficiency, no toxic effects, and adequate thermal properties. Coating materials can be used as armor materials against radiation. The main aim of this study is to select the most appropriate boron-doped surface coating material that provides excellent protection against neutron radiation and also has suitable physical properties based on expert opinions. Boron-doped surface coating materials are formulated in four different ratios as a result of the experimental study. Surface coating materials are ranked according to five criteria. Since these evaluation criteria are based on both experimental data and expert opinions, they have qualitative and quantitative information. Selecting the most appropriate coating material for radiation protection is a difficult process with conventional methods due to the consideration of qualitative and quantitative properties together. In this context, a combined approach that integrates the Spherical Fuzzy extension of Stepwise Weight Assessment Ratio Analysis (SF-SWARA) and Spherical Fuzzy extension of Evaluation based on Distance from Average Solution (SF-EDAS) methods is suggested. In the proposed framework, the main criteria are weighted using SF-SWARA to decrease the uncertainty in pairwise comparisons. Then, the surface coating material alternatives are analyzed and ranked according to SF-EDAS. The findings show that the most suitable coating material for radiation protection is the alternative containing 50% h-BN by mass.
