Abstract
Cesium 137 deposits are due to serious nuclear disaster (such as Chernobyl) and nuclear weapons tests. Due to the wide range of uses in environmental studies is important to know that radionuclide concentrations in environment. Soil samples were measured, in which 137 Cs activities varies between 4.3 and 114.3 Bq / kg. The highest concentrations were found in the top layers of the soil. From the soil depth profiles it can be observed the 137 Cs migration. Horizontal and vertical migration depends mainly on water runoff and the concentration of radionuclides, hydrological regimeand the type of soil. It is important to know the amount of radionuclides in the soil because there are already developed models which describe the radionuclides migration in different environments. One of the most studied radionuclide Cs-137 is due to its abundance and relatively long half-life. If the concentration of the radionuclides exceeds a certain value, it might be a threat to human health.
