As part of an interlaboratory program, the half life of 240 Pu has been measured on a shared 240 Pu oxide material. Grown-in daughter 236 U was measured at four intervals in the range of 0.94–1.1 yr by isotope-dilution mass spectrometry. The measur

Ten chemical treatments are evaluated for the attainment of isotopic equilibration of plutonium prior to its sorption on resin beads for assay of dissolved reactor fuel by isotope-dilution mass spectrometry. The one consistently reliable treatment is

As part of an inter-laboratory effort, the half life of 239 Pu has been measured on a shared 239 Pu metal material. Grown-in daughter 235 U was measured after intervals of 1.4 and 1.7 yr by isotope dilution mass spectrometry. The detemined half life

The half-life of 241 Pu has been measured by mass-spectrometric determinations of the decreasing ratio of a mixture of nearly equal numbers of atoms of 241 Pu and 242 Pu over decay periods of up to 3.6 yr. The measured half-life is 14.38 yr with an a
