TL;DR: An overview about the development of the radiochemical procedures for the separation of strontium and/or yttrium including the classical procedure based on a series of semi-selective precipitations, the ion exchange and solvent extraction procedures and the recently developed extraction chromatographic ones offering high selectivity are given.

TL;DR: A simple radiochemical procedure has been developed to separate lead and polonium simultaneously from different environmental and biological materials after adding 208Po tracer and lead carrier samples are decomposed using mineral acids.

TL;DR: In this paper, a combined procedure for sequential determination of low level activity concentrations of 90Sr,241Am and Pu radionuclides is described, which combines the well established, procedure for Pu analysis based on anion exchange, the powerful and selective method for Sr isolation based on extraction chromatography using Sr-Spec resin and finally it includes the application of the TRU-Spec column for separation and purification of the Am fraction.

TL;DR: This paper is intended to give an overview about the development of the radiochemical procedures from the early times of nuclear industry followed by a more detailed discussion of the recent developments from the 1990s until 2011.

TL;DR: A great number of analytical methods have been developed and applied for the determination of plutonium isotopes in environmental and nuclear samples using alpha spectrometry as discussed by the authors, which is intended to give an overview about the development of the radiochemical procedures for the separation of plutonium.
