Uranium, thorium and potassium in technogenic soils of industrial waste landfill

The authors have considered the features of uranium, thorium and potassium distribution in the upper layer of technogenic soil in closed industrial waste landfill in Ulan-Ude and the adjacent area. The average uranium content in the study area exceeds the regional background by 1.8 times, thorium by 2.0 times, and potassium by 1.7 times. It is shown that buried waste does not have a significant impact on the background radiation at the landfill location. The increased radiation level in this area is associated with the geochemical characteristics of the Sotnikovsky formation rock where the landfill is located.
