Due to the increasing of closed ventilation systems used in buildings, the risk of indoor radon is increased day by day. In this study, we selected two sample rooms to calculate the radon emission coefficient from different levels, radon concentration measured when the natural ventilation was completely closed and compared with the analytical results. The results clearly show the difference in the amount of radon concentration at different levels; then, by overcoming the common gaps in the entrance of the rooms, the natural ventilation caused by the temperature difference between the room and the outside is obtained. By substituting them in the analytical equations, the radon concentration is calculated with ventilation. The calculated results are in good agreement with the experimental results and show the important role of natural ventilation to reduce indoor radon even to over 90%.
