ABSTRACT
We have measured concentrations of thorium, uranium, and potassium in the shoreline soils. Each of these naturally occurring elements has isotopes that are radioactive and may increase the amount of exposure received by the populations living in the vicinity of the lake. These exposures can result in individuals receiving radiation dose in the form of external gamma radiation or internal alpha and beta emissions. Additionally, radon is a decay progeny of thorium and uranium and may result in increased radiation dose via the inhalation exposure pathway. The following study reports on the results of our soil analyses at Lake Issyk-Kyol.
