本研究自2011年9月在台灣東部安通溫泉建置地下水氡連續觀測站，並在實驗室長期採樣分析安通溫泉地下水氡濃度。以氣水兩相之分離係數連結實驗室水氡與現地氣氡濃度。根據長期監測數據(2011年9月至2012年10月)，安通溫泉現地連續觀測系統量測之地下水氡濃度的分離係數為0.19 ± 0.03。
本研究也自2003年7月在吉祥站長期採樣分析安通溫泉地下水氡濃度。發現在池上斷層，水氡異常下降振幅與地震矩規模(Mw)成正比。

We have been monitoring groundwater radon since September 2011 by both a continuous monitoring system and discrete sampling in the Antung hot spring in eastern Taiwan. The liquid scintillation method was adopted to determine the concentration of radon-222 in discrete groundwater samples. The continuous monitoring system measured the gas concentration of radon-222 in a separator through which the groundwater flowed through. Based on a long-term observation (from September 2011 to October 2012), the separation efficiency of radon-222 gas in the separator was determined at 0.19 ± 0.03. Both the continuous monitoring system and discrete sampling in the Antung hot spring agree with each other.
We have also been monitoring groundwater radon since July 2003 at well D1 in the Antung hot spring. For earthquakes occurring on the Longitudinal Valley Fault in eastern Taiwan, the observed radon minima decrease as the earthquake magnitude increases.
