Abstract

Uranium and thorium concentrations in water and in soil from Kazakhstan have been investigated. In some sampling points the uranium concentrations of drinking water, exceeded the WHO guideline level for drinking water. Thus, the human effect of uranium exposure from drinking water in these areas is significant. However, soil samples were the same as in the Nature. Irrigation systems in these areas would be easy for water carried in the drains mix with groundwater. The results here suggest that the uranium passes into the groundwater through the agriculture land by the above mechanism.
