Abstract

|
The objective of this study was to quantitatively measure the changes in radon concentration due to ventilation and air purification plants in the lower and upper floors of a building. This study measured and compared radon concentration in the lower and upper floors of the building by using a radon meter when the room was closed, it was ventilated, and air purification plants were installed at a specific time. One-way ANOVA was conducted to evaluate the effect of treatment (i.e., closure, ventilation, and air purification plants) on radon concentration. The results of this study showed that ventilation and air purification plants significantly decreased radon concentration in the lower and upper floors of the building, but the effect of ventilation and that of air purification plants were not significantly different. Therefore, it will be possible to reduce radon concentration effectively when ventilation and air purification plants are used appropriately.
