Abstract: The content of uranium and thorium in the soils and wood of the forestecosystems of the south-western Baikal region was determined. Soils geneticallyassociated with magmatic rocks contained more uranium (5.2 mg/kg) and thorium(15.0 mg/kg) compared to sedimentary rocks (1.1 and 2.2 mg/kg, respectively).The content of these elements in pine ash was also higher in phytocenosis formedon the products of weathering magmatic rocks - 0.21mg/kg (uranium) and 0.43mg/kg (thorium). On sedimentary rocks, these figures were significantly lower -0.082 and 0.141 mg/kg, respectively. The amount of uranium, relative to thorium,in plant and soil samples has always been higher than in soil-forming rock, whichindicates a higher biogeochemical activity of uranium in the ecosystems studied,compared to thorium.
