Description
A simple and fast method for uranium isotopes determination in low and intermediate level wastes from nuclear power plants using extraction chromatography is described. Following sample preparation, uranium is pre-concentrated by precipitation with iron(III) hydroxide and then separated using Dowex AG 1X8, 100-200mesh, resin. The separated uranium is electrodeposited onto stainless-steel discs and then measured by alpha spectrometry and the results were analyzed using WinALPHA software. The procedure was evaluated using 232U radiotracer. USGS uranium standard and intercomparison program were used as quality tools. (author)
