Background and anomalous levels of volume activity of radioactive gases in soil air were defined from the data of radioecological researches conducted by means of emanation survey on the territory of Kyiv. It was found that the higher and anomalous levels of volume activity of these gases are formed by fracture zones within the limits of which dangerous conditions may be formed for the inhabitants of the houses constructed above the zones. The area of the Prydniprovska part of Pechersk district of Kyiv has been researched in detail. Based on the levels of volume activity of radon and thoron this area is divided into two parts: the eastern part is radon-thoronsafe while the central and western ones, on the contrary, are dangerous. We think that it is connected with the submeridional radon-thoronbearing zone which exists due to presence of the fracture zone of the similar direction in the bowels.
