Abstract

Radon is a naturally occurring radioactive gas which may be found in high concentrations in indoor environments, such as homes and workplaces. The purpose of this study is to investigate the difference in indoor radon pollution level by floor based on the indoor radon concentration in a residential building. To achieve the objective, residential units in domestic apartment complexes were divided into lower, middle, and upper floors, and the indoor radon concentration for each group was measured and compared by using E-PERM and RAD7. During the measurement period, natural ventilation was performed using passive ventilation devices, and experimental errors were minimized by conducting a measuring environment without occupants in the residential unit. As a result of comparing the indoor radon concentration by floor level in a residential building, it was found that the average indoor radon concentration in the upper floors was higher than the average indoor radon concentration in the lower or middle floors. And it was found that the indoor radon concentration in the lower and middle floors gradually increased, while the indoor radon concentration in the upper floors increased or decreased.
