Analytical methods - Radionuclides
There are several validated analytical values available, e.g. on the IAEA homepage applying acid digestion of dry samples and separation of nuclides with e.g. ion exchange chromatography and then analyses with alpha spectrometry or by scintillation counting. Further methods are available but the methods are often isotope specific. Recent publication is e.g. a review by Shi et al., (2012 (Shi, K.L., Hou, X.L., Roos, P., Wu, W.S., Determination of technetium-99 in environmental samples: A review, Anal. Chim. Acta, 2012, 709, 1-20)).
