Abstract

Abstract: This is the first paper to report a potential map of radon ( 222 Rn) distribution in the Campania region of southern Italy, using the geostatistical kriging interpolation method using QGIS® software. The response variable is the 222 Rn indoor measurements, whereas proxy variables used as predictors are: geology, faults, soils permeability, meteorological/climatic parameters, 238 U distribution, 222 Rn emanation coefficients and exhalation rates, 226 Ra in building materials and gamma dose rate in dwellings. The map shows high radon potential areas in correspondence to the main volcanic centres and the faults network of the region. The map is a useful instrument to identify radon-prone areas and evaluate radon risk level for the population. Highlights: First characterization of 222 Rn potential in the Campania region (Southern Italy). Realization of 222 Rn map using geostatistical kriging interpolation method via GIS. Geological and radiometric parameters influencing 222 Rn emission are proxy variables. High 222 Rn potential levels occur at the main volcanic centres and faults network. Low 222 Rn levels are distribuited in spots and characterized by low permeability areas.
