Sažetak
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.
