Analysis of radionuclides in environmental samples

Abstract

The main steps of radionuclide determination in environmental samples are presented in this chapter. Details of a sample pretreatment, tracers, and carriers used in radiochemical analysis as well as methods of radionuclide preconcentration and separation are discussed. The comparison of characteristics is given for thinlayer sorbents based on various supports (wood cellulose, copolymer of styrene and divinylbenzene, slices and disks of cellulose triacetate, lavsan film, polyamide disks, polyacrylonitrile), which are used for selective preconcentration and separation of radionuclides. Main applications of extraction chromatographic resins in radiochemical analysis are also shown.
