Abstract

Because of their high radiotoxicities and their long half-lives, alpha-emitting nuclides are considered as one of the major risks for long-term, radioactive waste disposal. Compares sampling methods based on dissolution and leaching, combined with fusion techniques, with respect to their effectiveness. Particularly evaluates the application of the microwave dissolution technique for the destruction of various matrices from different origins. Preference was given to dissolution techniques without residues. Also investigates the efficiency of different separation techniques based on liquid-liquid extraction, liquid-solid extraction, extraction chromatography and selective liquid scintillation measurements. Selected routines were compared and qualified by sample exchange between different laboratories.
