A review o methods of radionuclides determination

Environmental radiochemical analysis have several steps such as sample pre-treatment, sample pre-concentration, separation and determination. Many separation methods, using solvent extraction and ion exchange chromatography are applied to the preconcentration and separation of radionuclides. These methods are time-consuming, use large amounts of strong acids and produce organic wastes. Recently, separation methods on the extraction chromatography have became increasingly popular in radiochemical analysis. In this presentation, we briefly summarize the published literature on principles and various applications of radioanalytical method that have been commonly used in radionuclide separations. (authors)
