[en] Radionuclide distributions in vertical cross sections taken from chernozem in a former garden and tillable field along the western fallout track at distances of 5, 13.5, and 22 km from the fourth block of the Chernobyl NPP are studied. The distributions through the chernozem cross sections are more complicated than those of sandy soil. Although the main mass of radionuclides in the cross sections is concentrated at depths of 0-3 cm, instances are observed where up to 5-15% of the radionuclides penetrate to greater depths
