URANIUM AND THORIUM CONTENT IN THE HUMIC ACIDS OF PALEOSOLS BURIED UNDER BARROWS AND CULTURAL HORIZONS OF ARCHAEOLOGICAL OBJECT STEPNOE 7 (SOUTHERN URALS)
In this paper the contribution of humic acids in the total soil pool of radioactive elements U and Th was estimated on the example of paleosols, buried in the Bronze Age, the cultural horizons of the same time and territorial localization, as well as modern background soils in forest-steppe conditions of Southern Urals.
