In this study, indoor radon concentrations were measured in 56 multiple-use facilities located in Gwangju areafrom December 2017 to December 2018. The average indoor radon concentration in underground space was51.70 Bq/m3, and that of the 1st floor was 38.73 Bq/m3, indicating that the indoor radon concentration ofunderground space was higher than that of the 1st floor. The indoor radon concentration was investigated accordingto the presence or absence of underground space. The concentration of radon on the 1st floor with undergroundspace was 37.25 Bq/m3, and the concentration of radon on the ground floor without underground space was47.94 Bq/m3. In the absence of underground space, indoor radon concentration was high. The indoor radonconcentration of buildings over 30 years old was 87.26 Bq/m3, indicating a significantly higher indoor radonconcentration compared to those of buildings less than 30 years old. The indoor radon concentration wasinvestigated according to the operation of a ventilator. The indoor radon concentration of space without anoperating ventilator was 52.17 Bq/m3, and that of space with a ventilator in operation for more than 8 hours perday was 36.31 Bq/m3. This result shows that the indoor radon concentration in the space with an operatingventilator is lower than the space where the ventilator is not in operation. The indoor radon concentration in thespace with an operating ventilation system was lower than that on the same floor of the same building, and theindoor radon concentration of enclosed space was about 4.4 times higher than that of open space in the samebuilding. In addition, the indoor radon concentration was measured according to the spatial features. Theconcentration of indoor radon of enclosed space was 64.76 Bq/m3, which is higher than those of an open spaceand an active space.
