Objective: This study was designed to compare construction types and seasonal radon concentrations in dwellings in Jeollabuk-do Province in Korea. Methods: The measurement of indoor radon concentrations in 79 dwellings using alpha-track detectors was performed every three months (seasonally) over one year between 2015 and 2016. Also, Radon concentrations in soil were measured in spring to investigate the correlations between the concentrations in soil and indoor air. Results: The annual average concentration of indoor radon for dwellings was 89.7±72.1(GM: 72.4) Bq/m3 , with a range (min-max) of 17.2 to 505.4 Bq/m3 . The highest indoor radon concentration was measured in winter and the lowest was shown in summer. The geometric mean of radon concentration in winter was 1.03-2.58 times higher than other seasons. Radon concentrations in soil were investigated at the depth of 1 m, and the concentrations ranged from 1,780 Bq/m3 to 123,264 Bq/m3 . This showed low correlations with indoor radon concentrations. Conclusions: Considering the comparison of seasonal radon concentrations and annual radon concentrations in this study, it is suggested that a future plan ought to be established for the management of indoor radon concentrations in dwellings. The data obtained from this study can be provided as a basis for preparing for legal regulations and public health protection manuals.
