DOI: 10.1021/acs.analchem.9b01737
Abstract: Until recently, the analysis and identification of nuclear fuel pellets in the context of a nuclear forensics investigation have been mainly focused on macroscopic characteristics such as fuel pellet dimensions, uranium enrichment, and other reactor-specific… read more here.
