The content and migration of natural radioactive isotopes in some lot of the surface soil of the Kharkiv region have been studied by the help of low background gamma spectroscopy. The migration series of radioactive elements (Ra > U > Th) in the soil of the Kharkiv region is determined, which corresponds to the humid type of climate. A high radium mobility as respect to uranium and thorium has been found. A high correlation between ⁴⁰K vs ²³²Th was found. Therefore, as a result of low mobility of thorium, it is possible to assume that thorium and potassium enter into the composition of the mother minerals. Correlation of ¹³⁷Cs with other radioactive isotopes was not significant in the soil of the Kharkiv region. This apparently indicates specifies in that a high mobility clay minerals can sorbing of cesium.
