Modern people, by adult standards, live about 81 percent of their daily lives indoors, such as eating and sleeping, and more than 90 percent of their daily lives, especially housewives and the elderly. In this trend, indoor environmental pollution is a major factor affecting human health. Among the various pollutants and harmful substances affecting the indoor environment, radon is a major concern in Korea recently. Most of them flow indoors from soil or building materials, and the indoor space is relatively high in single houses, which are directly in contact with the soil. In this study, the concentration of radon based on the presence of natural ventilation in an aged detached house was measured and compared to that of a radon recommended level. As a result, the level of radon before ventilation exceeded the recommended level, but only 30 minutes of natural ventilation allowed the level of radon to fall sharply.
