Isotopic uranium and plutonium analysis by alpha-particle spectrometry

The jackknife as an approach for uncertainty assessment in gamma spectrometric measurements of uranium isotope ratios

“…By combining Eqs. (4) and (5) the isotope ratios may be calculated. This can be done by fitting the isotope ratios and the parameters c 1 -c 5 in Eq.…”

“…mass spectrometry [3], alpha spectrometry [4] and gamma spectrometry [5]. Due to the long half life of the uranium isotopes mass spectrometry is by far the most sensitive method and offers also the lowest combined uncertainty.…”

Application of neural network method to detect type of uranium contamination by estimation of activity ratio in environmental alpha spectra

“…The measurement of the activity of radionuclides and their ratios are very interesting for determining the composition of environmental and non-environmental materials in many applications including nuclear power industry, radioactive waste management and disposal, health physics, geology, geochronology, and environmental science (Fleischer, 2008;Minteer et al, 2007;Rubio Montero et al, 2004). Among analytical methods for isotopic determination of radionuclides, Alpha-particle spectrometry with silicon detectors is known as an appropriate, precise, and low cost technique to assay alpha-particle emitting elements such as Uranium isotopes (Jia et al, 2005;García-Toraño, 2006;Kunzendorf, 1968;Minteer et al, 2007).…”

Evaluation of the suitability of neural network method for prediction of uranium activity ratio in environmental alpha spectra

“…The measurement of the alpha-activity ratios of uranium isotopes is very interesting for determining the composition of environmental and non-environmental materials in many applications including nuclear industry, radioactive waste management and disposal, health physics, geology, geochronology, and environmental science (Rubio Montero et al, 2004). The activity ratio depends on the extent of the enrichment process, which has caused depletion in the lighter uranium isotopes and can be used for distinguishing natural from anthropogenic sources of uranium.…”
