The authors have undertaken an in-depth comparison of mass- and gamma-ray spectrometric measurements of currently available plutonium isotopic reference materials. Based upon this review, it is evident that uncertainties assigned to minor isotope abundances are larger than appropriate for the current state of measurement and need to be reduced. The certified Pu isotopic abundance values, with a few exceptions, appear to be accurate to within about +. 0.2%. The branching fraction for the 152.7-keV gamma ray from /sup 238/Pu, measured in this work, is consistent with other recently published values of about 9.3 x 10/sup -6/ ..gamma../disintegration.
