Abstract
Processes of sorption and desorption of cesium and strontium radionuclides by main rock-forming minerals and soil samples from Kola PEN have been studied. It has been demonstrated that it is advisable that acidified solution of sodium chloride should be used to desorb radionuclides. A promising flow diagram has been proposed for deactivation of soils that have been polluted by radionuclides. The flow diagram involves a high degree of concentrating the radionuclides within a product to be buried, the use of a recycled solution that is intended for soil deactivation, as well as the freedom from the secondary pollution of soil by reagents harmful for the environment.
