Improved combined HRGS-TIMS method for rapid determination of Pu in nuclear material samples collected in the Rokkasho reprocessing plant

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…Plutonium was also the focus of a study by Kim et al , who utilised gamma spectroscopy and TIMS without chemical separation for Pu assay in pure plutonium and uranium-plutonium mixed solutions from a reprocessing site in Japan. 199 The relative bias of <0.01% allows this approach to be used as a support or alternative to traditional IDMS and K-edge densitometry without compromising accuracy and precision.…”
