Potential of Spectrum Categorisation Concepts using Radionuclide Ratios for Comprehensive Nuclear-Test-Ban Treaty Verification


In order to develop further existing categorisation concepts for CTBT verification, xenon ratios have been used to help identify nuclear explosions. 25,726 noble gas spectra have been analysed and an additional state-of-health criterion has been introduced.
