Main results of field work (Action A1)

Work on Action A1 has recently been concluded, with the integration and processing of data collected from existing geological and geochemical databases and from RESPIRE field surveys conducted at the project’s study sites (Caprarola, Celleno and Ciampino municipalities).

Geogenic Radon Potential (GRP) maps were obtained by applying Empirical Bayesian Kriging Regression (EBKR), using soil gas radon as the response variable and a number of related proxy variables (i.e., content of the radiogenic parent nuclides, the emanation coefficient of the outcropping rocks, the diffusive 222Rn flux from the soil, the soil-gas CO2 concentration, the Digital Terrain Model, the permeability of the outcropping rocks, and the terrestrial gamma dose rate of the shallow lithology). The resultant maps have been presented at various international and national conferences.
