Separation of species of radionuclides from precipitation and fallout samples

The experience with the determination of radionuclide species using the method based on the in-line separation of these species by filtration and retention on columns of cation and anion exchange resins and activated charcoal, respectively, is presented. For the combined precipitation and fallout samples, from the point of view of their sampling, passive and indicatively active arrangements have been proved. During 1984-1986 some real samples have been analyzed and the results are briefly discussed and evaluated. (author) 32 refs.; 3 figs.; 2 tabs
