Abstract:Nuclear forensics is an important tool for combating illegal trafficking of nuclear and other radioactive material, which can be used to obtain information on the processing history of the material and on its intended use. Previous research has mainly focused on the bulk analysis and characterization of elemental and isotopic characteristics. In recent years, with the development of microanalysis technology, the study of spatial distribution characteristics of elements and isotopes and microscopic morphological characteristics at the micrometer and nanometer scales has become a hot topic in nuclear forensics research. This article is based on the research achievements of nuclear forensic science both domestically and internationally in recent years, and provides a detailed introduction to the application research progress of elemental imaging technology in the field of material analysis of nuclear forensics, including element and isotope imaging, and microscopic morphology.
