No full textDetermination of the isotopic ratio U-234/U-238 in liquid scintillation and environmental applications
No full textWe describe a procedure to measure the isotopic ratio U-234/U-238 in liquid samples. This method combines an extractive technique, liquid scintillation counting with alpha/beta discrimination and a fit procedure of alpha ADC spectra. Its main advantages are: high detection efficiencies for a emissions, energy sensitivity, rapid and easy preparation of the samples. This makes the technique suitable for environmental survey. We tested the method on a wide set of NBS standards, considering U-235 enrichments up to 5% (the maximum value allowed for civil uses). Results on samples collected on field were validated by a comparison with ICP mass spectrometry. (c) 2005 Elsevier B.V. All rights reserved
