Data in this paper summarizes the authors' experience in obtaining plutonium and americium isotopic data using two systems: a 70-cc Ge(Li) system with 1.8-keV resolution at 1332 keV for acquisition of spectra up to 700-keV gamma-ray energy and a 1-cc planar system with 600-eV resolution at 122 keV for the acquisition of spectra up to 220 keV. Plutonium samples include ash samples with plutonium-240 concentrations of 9 to 20 percent; plutonium metal samples of 6 percent plutonium-240; ZPPR fuel pins; and various waste categories of 6 percent-plutonium-240 material. Nondestructive isotopic ratios obtained by gamma-ray spectroscopy are compared to chemical data obtained from these samples.
