摘要

Neutrons, owing to their charge neutrality and distinctive interaction cross sections, have evolved into indispensable probes across scientific and technological domains. This review consolidates contemporary progress in neutron-based techniques, from imaging and activation to scattering, spectroscopy, and dosimetry, highlighting their complementary advantages and emerging frontiers. Neutron radiography and tomography now provide high-resolution, non-destructive 2D and 3D visualization of internal structures, bridging diagnostic gaps left by X-ray methods. Activation-based approaches such as neutron activation analysis and depth profiling continue to deliver quantitative, multi-element, and depth-resolved information critical for forensics, environmental, and semiconductor research. Advanced scattering and spectroscopy techniques, particularly time-of-flight and spin-echo methods, reveal atomic-scale dynamics and magnetic ordering with exceptional precision. Parallel advancements in detector and dosimeter technologies mark a paradigm shift toward compact, semiconductor- and scintillator-based systems with improved efficiency, radiation hardness, and scalability. Emerging materials, including diamond, SiC, GaN, h-BN, and hybrid perovskites, demonstrate transformative potential for high-temperature and mixed-field neutron environments. Moreover, the integration of artificial intelligence (AI) and machine learning (ML) in signal discrimination, dose prediction, and circuit optimization introduces adaptive, self-calibrating capabilities and accelerates data processing. By bridging fundamental neutron–matter interactions with materials innovation and AI-driven analytics, this review outlines the trajectory toward next-generation, intelligent neutron detection systems tailored for precision science, medical therapy, and nuclear safety.
