Groundwater-surface water interaction is important for water resource management and aquatic ecosystem protection. Radon (Rn) has been widely used in the investigation of groundwater-surface water interaction owing to its application advantages, such as its large concentration difference between groundwater and surface water, noble gas properties, and ease of measurement. In this study, we analyzed Rn applications in different surface waters (sea, river, lake, etc.) and identified the Rn concentration variation in groundwater as a key challenge in the estimation of groundwater discharge into surface water. When estimating submarine groundwater discharge (SGD), Rn mixing loss and its variable concentrations in seawater, and the complexity of SGD components would produce uncertainties in the estimation results. Also, it is difficult to determine Rn atmospheric loss when estimating riverine groundwater discharge using the Rn method. Further, little attention has been paid to the application of Rn in tracing surface water flow into groundwater. Thus, future studies on Rn application in regarding to groundwater-surface water interaction should focus on (1) reducing final uncertainty in Rn-based estimation of groundwater discharge due to variable Rn concentrations in groundwater; (2) accurately characterizing the Rn atmospheric loss for different surface waters under different hydrological conditions; (3) expanding scientific applications of the Rn method; and (4) developing a software that integrates the Rn mass balance model and uncertainty analysis.
