Selective liquid scintillation method of uranium α-spectrometry

Natural radionuclides measurements in drinking water by liquid scintillation counting methods and results

“…Other actinides like thorium, plutonium and americium can be co-extracted; if necessary, complexing agents can be added to the water sample to suppress such interferences. 13 Liquid scintillation counting coupled to selective uranium extraction was used in this work to assess uranium content in waters. Experimental conditions were optimized with regard to the cocktail selection, pretreatment and counting procedure.…”

Comparison of radiometric and non-radiometric methods for uranium determination in groundwater of Punjab, India

“…Alpha Spectroscopy is considered to be a very precise, versatile and sensitive method for uranium, but preparation of the alpha sources is laborious and time consuming and correction factors are needed for self-absorption and geometry [19,20]. Liquid scintillation counting (LSC) technique was extensively used for a-emitters [21][22][23] and uranium is determined in several types of samples, e.g, phosphate rocks [24], environmental samples associated with uranium mining and milling [25,26], water samples [27] and geological samples [28].…”
