Abstract
In recent years, more attention is paid to radon hazard, especially in active zones of modern faults. It is known that radon is generated in geodynamically active zones of cover deposits associated with discontinuous in basement rocks. The greatest danger is the areas where such faults are localized in shallow granite.
In most of the territory of Ukraine, radon is not monitored; there are practically no maps of radon hazard. The existing development of radon protection suffers from the lack of reliable methods for forecasting the radon hazard of territories and buildings. The volume of point studies is very limited. For the reliable prediction of the radon anomalies throughout the territory, it is necessary to attract geological and geophysical materials which characterize tectonic, the material composition of the upper part of the Earth’s crust. The authors proposed to use the regional and local components of the geomagnetic field. The sources of magnetic and radon anomalies are primarily determined by the magnetic and radioactive properties of rocks. The investigation of the Ukrainian shield magmatic rocks magnetic susceptibility and radioactivity showed that rocks with increased radioactivity have weak magnetic properties, i.e. an inverse relationship is established between these parameters. The result obtained shows that radon and uranium anomalies and deposits correlate mainly with negative anomalies of the magnetic field of the regional and local classes and with faults of the northwestern and latitudinal strike, or the nodes of their intersection.
