RADIONUCLIDE DISTRIBUTIONS IN VERTICAL SOIL CROSS-SECTIONS OF THE CHERNOBYL NPP 30-KILOMETER ZONE ALONG THE WESTERN FALLOUT TRACK .2. CHERNOZEM

Radionuclide distributions in vertical cross sections taken from chern ozem in a former garden and tillable field along the western fallout t rack at distances of 5, 13.5, and 22 km from the fourth block of the C hernobyl NPP are studied. The distributions through the chernozem cros s sections are more complicated than those of sandy soil. Although the main mass of radionuclides in the cross sections is concentrated at d epths of 0-3 cm, instances are observed where up to 5-15% of the radio nuclides penetrate to greater depths.
