| Abstract: | Three-dimensional localization of neutron-emitting materials is crucial for minimizing personnel radiation exposure during nuclear decommissioning and nuclear safety activities. To address this challenge, this study proposes a localization method based on double-scattering principle and a dedicated reconstruction algorithm. This study is comprised of two main parts. First, a double-layer scintillator array detector was designed. Its key parameters were optimized to achieve a balance between coincidence detection efficiency and spatial resolution. Second, a three-dimensional localization algorithm was developed. This algorithm determines the optimal imaging plane and reconstructs a heatmap, leading to three-dimensional localization. The performance of the double-scattering imaging system was evaluated via simulations. The results demonstrated that the neutron source can be localized within a defined spatial area with centimeter-level accuracy. This study provides a practical solution for the three-dimensional localization of neutron-emitting materials and demonstrates its significant application potential in the field of nuclear decommissioning.
