radon activity concentration in soil gas

Mapping the geogenic radon potential in Germany is a research project initiated by the German Federal Ministry for the Environment, Conservation and Reactor Safety. The project was aimed to develop a standard methodology for the estimation of a geogenic radon potential and to apply this method to map the region of Germany as an overview for planning purposes. The regionalization results from a distance-weighted interpolation of the site-specific values of radon concentration in soil gas and in-situ gas permeability of soils on a regular grid considering the corresponding geological units.
