ANALYSIS OF RADON TIME SERIES RECORDED IN SLOVAK AND CZECH CAVES FOR THE DETECTION OF ANOMALIES DUE TO SEISMIC PHENOMENA

摘要

Radon is utilized by the scientific community as a tracer in the study of the earthquake dynamics. The present paper approaches this scope, with the aim of analyzing radon activity concentration time series for 1 y (from 1 July 2016 to 30 June 2017) recorded in one Slovak and two Czech caves. Radon time series exhibited a seasonal fluctuation pattern, particularly with higher values in the summer season, caused by temperature differences between inside and outside envi- ronments.
