In this study, based on the results of real-time monitoring of <SUP>222</SUP><SUP></SUP>Rn at the Gosan site in Jeju Island, Korea from 2016 to 2020, its background concentration and time series fluctuation characteristics were investigated. In addition, by comparing the variations of ambient radon and fine particle concentrations according to the inflow path of airflow, the possibility of using radon tracer to understand the long-range transport of air pollutants was estimated. The daily-mean concentration of atmospheric radon was 2,507 mBq m<SUP>-3</SUP>. On monthly variations, the mean concentration of radon in November was 3,229 mBq m<SUP>-3</SUP>, the highest as almost twice as that in July (1,650 mBq m<SUP>-3</SUP>). The cyclic seasonality showed to be the maximum in winter and the minimum at summer with 1.5 times difference, that was consistent with the reduction in continental fetch going to summer. On the diurnal variations, the radon concentration has increased during the nighttime with the maximum (2,871 mBq m<SUP>-3</SUP>) around 6 a.m., and then gradually decreased throughout the daytime with the minimum (2,051 mBq m<SUP>-3</SUP>) around 3 p.m. During the winter season, radon’s daily variations showed relatively small fluctuations due to little change in atmospheric mixing depth. By contrast, a large amplitude was observed in summer due to a relatively large variability in mixing depth. On the cluster back-trajectories of air masses, the radon concentrations from China continent were as about twice as high mostly than those from the North Pacific Ocean. Interestingly, the high PM<SUB>10</SUB> concentration was found as the high radon concentrations.
