Radon concentration in thermal springs at Hotavlje and Bled has been measured from October 2005 to June 2008 and from October 2005 to September 2007, respectively. At both locations several anomalies in radon concentration were observed, that might have been caused by seismic events. In this study all earthquakes with ratio (D/R) between strain radius (D) and distance to the epicenter (R) greater than 0.5 were taken into account. Five earthquakes occurred in the vicinity of Bled in this period, the strongest at a distance of 17 km with the magnitude ML=3.8 and four radon anomalies were observed. At Hotavlje fourteen earthquakes occurred in the vicinity with D/R ratio from 0.5 to 2.9. During this period three radon anomalies were observed.
分别于2005年10月至2008年6月以及2005年10月至2007年9月对霍塔夫列和布莱德温泉中的氡浓度进行了测量。在这两个地点均观测到了氡浓度的若干异常情况，这些异常可能是由地震事件引起的。在本研究中，考虑了应变半径（D）与震中距离（R）之比（D/R）大于0.5的所有地震。在此期间，布莱德附近发生了5次地震，最强的一次距离为17公里，震级ML = 3.8，并观测到4次氡异常。在霍塔夫列附近发生了14次地震，D/R比值在0.5至2.9之间。在此期间观测到3次氡异常。
