The main part of the radiation dose that people receive from natural radioactive sources is due to inhalation of radon and its decay products. It has been proven that exposure to high levels of radon (222Rn) increases the risk of developing lung cancer in humans, especially in indoor spaces in combination with tobacco smoke. Radon is a natural gas and originates from the decay chain of uranium (238U), which is found in soil and rocks. In the outdoor atmosphere, its concentrations are lower, but in buildings the concentration can rise to dangerous levels. Therefore, its monitoring can help in giving recommendations for the introduction of protective measures against high radon concentrations. Radon measurement was performed with the Rad 07 device (active method) in indoor spaces. Five rooms in schools where radon was continuously measured for seven days are shown. The rooms had different air exchange rates, which is reflected in the results on radon concentration levels. The research results have great practical application, especially in rooms that are closed for a long period of time. It has been shown that the air exchange rate plays a key role in radon concentrations and thus on the effective dose received by students and school employees.
