Abstract: The investigation of migration of Chornobyl-origin radionuclides was carried out in soil profiles of the Glubokoe lake within 5 km ChNPP zone. The soil samples were taken along four experimental trenches in 2002. γ- and β-emanations of these samples were investigated after the corresponding processing. ^134,137Cs, ^154,155Eu, ²⁴¹Am isotopes were identified very well. ⁹⁰Sr isotope was identified as a result of research of the thin layers β-spectra. ^238+239Pu isotopes were determined using nondestructive control methods. The migration of ^134,137Cs, ^154,155Eu, ⁹⁰Sr, ²⁴¹Am and the ^238+239Pu isotopes was observed to the depth of 30 cm. The obtained data are analyzed.
