Summary

The search for practical techniques to mitigate radon in houses leaded the authors to develop a methodology for identifying radon 222 sources and transfer ways into the upper rooms, based on the study of some houses with relatively high radon levels. The study consisted in the measurements of radon 222 concentration in the air, the emanation flux through the soil and walls (indoors and outdoors), potential alpha energy concentration of radon daughters and ventilation rate. Meanwhile, the authors determined the percentage of unattached fraction and the activity size distributions of radon daughters which was compared to those of non radioactive aerosol particles. The analysis of the results shows that it is possible to select a few number of parameters allowing a rapid "radon diagnostic".
