To help assure that analysis data of known quality will be produced in support of demonstration programs at the Fuel Conditioning Facility at Argonne National Laboratory-West (Idaho Falls, ID), a special reference material has been prepared and chara

Copper, chromium, and cobalt species present in filtered wastewater effluent were separated by cation exchange and reverse phase chromatography. Three sample fractions were obtained: one containing metal cations (i.e., trivalent Cr, divalent Cu, and

This report describes experimental studies to evaluate the use of EPA SW-846 method 3051 for preparation and dissolution of solid samples for Hg analysis. The study showed that the method is effective in dissolution of four sample types without signi

The /sup 239/Pu half-life was measured both by ..cap alpha.. counting with an intermediate geometry proportional counter and by mass spectrometric measurements of the rate of /sup 235/U formation, using isotopic dilution with titrated /sup 233/U and

The half-life of $^{230}\mathrm{Th}$ was measured by the specific activity method. Alpha counting was done in a low geometry counter whose geometry factor was calculated from its dimensions. Sample weights were determined by isotopic dilution. Measur

Using a method developed earlier [1], we have made a precision measurement of the specific activity of 236 U. Samples were prepared by molecular plating and counted in an intermediate geometry alpha proportional counter with a flat pulse height plate

New determinations of the half-lives of $^{235}\mathrm{U}$ and $^{238}\mathrm{U}$ have been made. Improved techniques have allowed the half-life values to be measured with greater accuracy than has been heretofore achieved. Samples were prepared by m

Two nearly independent methods have been used for measuring the half life of 239Pu. In one, the alpha-particle activity of a known mass of plutonium of known isotopic composition (>99.9% 239Pu) was measured using a defined-solid-angle alpha-particle

Uranium in terrestrial volcanic ejecta from mantle-related sources has been analyzed mass spectrometrically. The objective was to seek supporting evidence for or refutation isotopic variations reported by Fried et al. (1985) for some such samples. Th
