The influence of constructional features and of buildings on indoor Rn entry: experimental research in Catania city (Italy)

摘要

The research, carried out for three years, take place within the sphere of ERRICCA (European Research into Radon Construction Concerted Action) funded in part by the European Commission and culminated in final workshop "Radon in The Living Environments" organized by National Technical University of Athens (April 1999). Authors held inquires and radiation measurements to seek out constructive features of buildings influencing Radon indoor admittance. The measured concentrations have been correlated with constructive features of buildings to discover the most significant connections. The results of research point-out that the buildings features and the placements of constructions on urban agglomeration are influent on Rn admittance into the indoor environments and allow the factors that producing indoor store of gas. At least, people built for, each general buildings typology, a general guidance that permits to choice the most suitable control technics to full down Rn concentrations to safe values for health of inhabitants.
