Separation of species of radionuclides from precipitation and fallout samples

The experience with determination of species of radionuclides using the method based on 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 of the method have been proved. During 1984–1986 some real samples from the locality of the Institute have been analyzed, obtained results are briefly discussed and evaluated.
