Abstract
The present status of the non-destructive plutonium isotopic analysis technique using high-resolution gamma spectrometry is evaluated in the light of results which have been obtained from interlaboratory comparison measurements initiated and organized by the ESARDA-Working Group on NDA techniques. The intercomparison exercise included both laboratories' own measurements on the plutonium isotopic reference materials NBS-SRM 946, 947, 948 and the analysis of gamma spectra from these materials distributed to the participating laboratories.
