Abstract
Radon-emanation detectors of an original design, using the LR-115 solid nuclear-track detector films, have been constructed for radon concentration measurements in soil and water. Temporal radon variations, as well as barometric pressure, atmospheric precipitation and temperature were observed during a year. A negative correlation between the radon concentration in soil and barometric pressure was found. For two recorded earthquakes in 1998, the soil radon anomalies were observed, about one month before each quake. It seems that by using the radon-emanation detector, earthquakes can be predicted.
