Brief Method Summary
|
Uranium from acid leached, dry-ashed and wet-ashed materials is equilibrated with 232U tracer, and is isolated by anion exchange chromatography. The separated U isotopes are microprecipitated for alpha spectrometry (Hindman, 1983; Sill and Williams, 1981; Welford et al., 1960). |
|
Scope and Application
|
This procedure has been used to analyze soft tissue, vegetation, water, and air filter samples to determine isotopic uranium. |
