Long-term monitoring of indoor radon - second phase (Action B2)

The action includes the long-term monitoring of indoor radon concentrations and the building selection for the installation of remediation systems. The long-term  monitoring covering the summer period (July- September 2019) has been completed. Indoor radon concentrations in the three Italian
municipalities of Ciampino, Caprarola and Celleno are quite different; during winter, in Caprarola were  measured the highest values, in Ciampino the lower. As expected, the median values of indoor radon concentrations were lower during the summer period than those measured during the winter period, in all
municipalities. Building selection was based on results from long-term monitoring of indoor radon concentrations during winter period and additional criteria which included building characteristics (geometry, building materials, etc.) and geographical distribution of buildings, in relation with the constructed GRP maps of the three sites. The final list of selected buildings was also affected by the essential approval of availability of individual citizen for private houses, and of local
administrative staff for public buildings.
