High Radon concentration in the karst area of south Puglia, Italy

Information obtained from paragraphs 1 and 2 provide the "Indices of potential risk of the generation, emanation and diffusion of Radon”; this hazard indices allow to optimize the measurements distribution in soils. We Identify the sub-areas of the zone study that can be characterized by high Radon concentrations, dividing these by "natural" hypothetical lines such as the lithology changing, permeability, subsoil structure, etc. ... The preliminary study allows the optimisation of sampling strategy based on not Uniform distribution of “in situ” measures, where to intensive the measures and where to make only control points of Radon concentration.
