[en] Rapid methods for the determination of radionuclides in various environmental matrices are of great importance especially in case of emergency situations. Further to their application in case of emergency rapid methods are also of advantage for laboratories routine analysis programs since they allow gaining time and efficiency thus resulting in increased sample throughput. In both cases, emergency situations and routine analysis, it is crucial to obtain accurate and reliable results. The quality of the results depends on an efficient solubilisation of the radionuclides of interest from the sample matrix as well as on a clean separation of the analytes from sample matrix and other analytes. Further an appropriate preparation of the test samples prior to the measurement is of great importance. This poster gives an overview of rapid methods for the determination of actinides, radiostrontium and Cl-36/I-129 from various matrices. The subjects of solubilisation of the analytes and sample preparation are also addressed. (authors)
