THE GEOGENIC RADON POTENTIAL MAP OF THE ASPIRING 'BUZĂU LAND' GEOPARK.

Mapping the geogenic radon potential in Buzău County is part of a research project aiming to apply research for sustainable development and economic growth following the principles of geoconservation in order to support the 'Buzău Land' UNESCO Geopark initiative. The mapping of geogenic radon will be used as an overview for planning purposes. The main geological formations of the studied area were identified as Cretaceous and Paleogene flysch, included in a thin-skinned nappes pile and consisting of alternating sandstones, marls, clays and, subordinately, conglomerates, all tightly folded or faulted. Significant variations in the concentration of radon were therefore determined in the ground. However, no high values were determined, the maximum measured activity concentration being 101.6 kBq m-3.
