Airborne gamma-spectrometric detection and types of geochemical radioactive anomalies in Serbia and adjacent areas and their ecological importance

The territory of Serbia and adjacent areas is built up by many geological formations of diverse composition/age belonging to a few major geostructural units. Some of them may contain enrichments of radioactive elements may be risks (as sources of radioactivity) to the health of population. By the airborne gamma-spectrometric surveys, applied at a few localities in diverse geological units, zones of geochemically anomalous radio-activity were discovered, related to different geological-geochemical systems. The anomalies, defined by gamma-ray radioactivity, a total and specific ones (of K-40, and Bi-214 and Tl-208, as indicators of U and Th, respectively), differ in both geochemical types and environmental-health impacts.
