“…To further evaluate the new TEVA method, we performed an analysis of an ancient carbonate sample obtained from a relevant geological formation at the Lake Bonneville site in western Utah. These samples were weighed and acid digested by routine sample preparation techniques and analyzed by isotope dilution alpha-spectrometry (Makarova et al, 1983; Tiessen et al, 1983; Oviatt, 1997). …”

“…We evaluated the method based on critical metrics: achievable radiochemical yield of the tracers; the impurities in each alpha-spectra; and control-spike recovery (Table 1) (Makarova et al, 1983). Radiochemical tracer yields were >90% for U and Th for these experiments, while Pa yields were slightly lower (Table 1).…”

“…In our first attempt, samples (0.5 g) were digested to dissolve the carbonate material according to established procedures (Tiessen et al, 1983) and analyzed by isotope dilution alpha-spectrometry (Makarova et al, 1983). Using standard Bateman equation-based dating techniques, our preliminary estimate of the formation of the deposit is approximately 39,500 ( 230 Th/ 234 U) and 40,000 ( 231 Pa/ 235 U) years before present.…”

“…Alpha-counting sources were counted for approximately 168 h, with a matched count-time background subtraction of each region of interest (ROI) applied to obtain background corrected integrated count rates. Standard isotope dilution techniques were used to calculate the apparent activity of added controls 230 Th and U-NAT radionuclides based on the ratio of control to added 232 U and 228 Th integrated counts (Makarova et al, 1983). …”

“…Within this context, we explored the potential to develop a new method, which might combine improved elemental purity of U, Th, and Pa fractions, with fewer steps, and less waste. In this paper, we describe this new method and present the application of the approach for the isotope dilution alpha-spectrometry analysis and preliminary age determination of an ancient carbonate sample obtained from the Lake Bonneville site in western Utah (Makarova et al, 1983; Oviatt, 1997). The method is relatively rapid; produces only small amounts of chemical waste; utilizes a commercially-available extraction chromatographic resin (TEVA; Eichrom Technologies, Inc.); and employs standard laboratory reagents.…”

Uranium-series dating techniques require the isolation of radionuclides in high yields and in fractions free of impurities. Within this context, we describe a novel-rapid method for the separation and purification of U, Th, and Pa. The method takes advantage of differences in the chemistry of U, Th, and Pa, utilizing a commercially-available extraction chromatographic resin (TEVA) and standard reagents. The elution behavior of U, Th, and Pa were optimized using liquid scintillation counting techniques and fractional purity was evaluated by alpha-spectrometry. The overall method was further assessed by isotope dilution alpha-spectrometry for the preliminary age determination of an ancient carbonate sample obtained from the Lake Bonneville site in western Utah (United States). Preliminary evaluations of the method produced elemental purity of greater than 99.99% and radiochemical recoveries exceeding 90% for U and Th and 85% for Pa. Excellent purity and yields (76% for U, 96% for Th and 55% for Pa) were also obtained for the analysis of the carbonate samples and the preliminary Pa and Th ages of about 39,000 years before present are consistent with 14C-derived age of the material.

A procedure was developed for isolation and determination of the isotope composition and content of U and Pu on the ultrasmall level in environmental samples of technogenic origin, characterized by a small mass (up to 0.l g) and complex macrocomposition. The procedure is based on isotope dilution and mass-spectrometric measurement of the isotope ratios (IDMS). Subnanogram quantities of U and Pu were isolated using a modification of resin bead technique, involving sorption on a limited number of anion exchanger beads and allowing, after desorption, analysis of the solutions containing the selectively isolated nanogram quantities of U or 10 312 310 315 g of Pu. The measurements were carried out on thermal ionization mass spectrometers manufactured in Ukraine and Russia with a modernized ion registration system utilizing a position-sensitive detector based on microchannel plates. Uranium was analyzed by the laser luminescence method suitable for measuring fractions of nanograms of U accurately to within 10%. This procedure, combining highly sensitive methods of isolation of ultrasmall quantities of U and Pu with the mass-spectrometric method of analysis, is applied at the Radium Institute (acting as a national laboratory of IAEA) and at the Institute of Analytical Instrument Designing, Russian Academy of Sciences, in analysis of inspection samples submitted by IAEA for monitoring the activity of nuclear facilities under the Treaty on Nonproliferation of Nuclear Weapons.
