반지하 주거공간의 환기방법에 따른 라돈 농도에 관한 연구

Most people living in the 21st century are living in indoor environments more than 80 percent of the day, and the quality of life is becoming more important. Indoor air quality makes up a large part of it. Radon's main source is soil, and it has a lasting effect on our living on the ground. Radon is a highly dangerous substance that has been named after smoking by the World Health Organization(WHO) for the causes of lung cancer. As a result, this study informs modern people about the risk of Radon, and selects a semi-basement residential space that is likely to be affected by Radon among indoor spaces to measure the Radon concentration and to reduce the radon concentration. The measurement method was to determine the location and time of the measurement, reflecting the lifestyle patterns of the residents. Overall, the measurements are shown to be highly irregular due to various environmental factors, but they are clearly lower when ventilation is not performed. The effects were high in the order of 24H forced ventilation, natural ventilation, and forced ventilation. The combination of natural and forced ventilation is important.
