Alpha spectormetry measurement reproducibility study for uranium, plutonium, and americium in water at Rocky Flats environmental technology site.
An evaluation of alpha-spectrometry measurement reproducibility of low level 241Am, 239pU, 238U, and 234U concentrations in surface and ground waters at the Rocky Flats Environmental Technology Site was performed using the known and measured values of laboratory control samples. Tile purpose of the evaluation was to determine the lower limits of reliable quantitative measurement performed on recent surface water samples and historic ground water samples using alpha spectrometry. At known concentrations between 0.1 and 30 pCi L(-1) (3.7 x 10(-3) to 1.11 Bq (L-1)), the reproducibility is dependent on the magnitude of the measurement and is quantifiably reproducible to one significant figure.
