Abstract
The report discusses geological sources of radon anomalies in Kyiv and its relationship with the magnetic field. Radon and other radioactive gases have dominant role in total level of the contamination inside buildings and in the air of soils. Identification and evaluation of radon areas is an urgent task to study its effects on human health. Magnetic survey can be used as indirect method to estimate radon levels in the surface part of the crust and in the airspace because measurements of radon concentration have point character. Acid igneous rocks of the basement (characterized by a weak magnetization ) are sources of radon anomalies. This connection is a physical and geological justification for such phenomenon. Consequently, the radon anomalies will correlate with the negative anomalies of the geomagnetic field near faults and fracture zones.
The result obtained can be used within the Ukrainian shield (acid or alkaline rocks, fractures zones and faults should be located in the investigation area) for building predictive models of radon hazard according to magnetic survey.
