The passive gamma-ray spectroscopy for plutonium nuclear fuels was performed using a small volume CeBr detector specific to high dose-rate measurements. This presentation reports that the wide energy range of gamma-ray spectra was obtained by the spectroscopy, and the energy range covered the principal gamma-decay lines of 59.5 keV emitted from Am and 2615 keV emitted from Tl, which is a descendant nuclide of Pu, comparing the measurements using HPGe.
