Abstract
In this study, the variation of indoor and soil radon concentrations were measured at a test bed (detached house), and correlation analysis was performed using linear regression. The results showed that the average concentration of indoor radon was increased by about 20% when the heater was operated in the house, but it was decreased by 15% when the ventilation system was on. In the changes of seasonal radon concentrations, soil and indoor radon concentrations in winter were higher than in summer. Statistical analysis showed a weak correlation between the soil radon and indoor radon, but the correlation (R=0.852, $R^2=0.726$) was relatively high at exhaust condition in the winter. It is difficult to extrapolate the results of the study to the general cases because radon distribution is highly site-specific, but the result of this study could be used as a reference for radon management and reduction of detached house in the future investigations.
