The principal aim of this diploma thesis was to monitor radon volume activity from the ground at the buildings of selected high schools in the South Bohemian Region. The theoretical part of the diploma thesis was processed by secondary data analysis. With the help of professional literature, valid legislation and Internet texts, radon problems were analyzed. I dealt with the penetration of radon from the subsoil, water and construction material into the buildings. Furthermore, its biological effects on human health, radon program, subsidies and legislation regulating radon problems. The research was proceed through a qualitative search using secondary data analysis. The needful data for the research part of the diploma thesis I got from my own measurement of radon volume activity in five high schools in the South Bohemian Region, supplemented by the measurement of carbon dioxide. I measured the radon volume activity with the continual monitor Radim 5B and the carbon dioxide concentration with the Wöhler KM 410 for climate assessment. Measured result values were processed using special programs on the computer and the results were displayed in graphs. The measurements made it clear that in selected schools up to one have not a greater problem with radon. From the measured values of carbon dioxide concentrations is evident that in schools is not enough ventilation, and the insulation of the building and the replacement of the windows on behalf of Eurowindows plastic or wooden has an fundamental effect. Consequently, the concentration of radon is then higher than it could be. In view of these facts, it would be advisable to carry out a ventilation system in schools or create vents in the masonry to ensure that clean air is drawn into the building.
