Abstract
The distribution of natural radioactive elements (uranium, radium, thorium and potassium) in the soils of the Priobskoye plateau and the eastern part of the Kulunda plain depicting different physical geographical zones is presented. The most evident radiogeochemical zoning is revealed for uranium and potassium in the autonomous landscapes. The concentrations of radium and thorium remain at the same level without any noticeable redistribution. A method is proposed to estimate uranium carry-over during Holocene (12
