Environmental monitoring of radon in soil during a very seismically active period occurred in South West Greece
Abstract
This paper focuses on the environmental monitoring of radon in soil as a potential trace gas in the search of earthquake precursors. The paper reports the following: (a) Pre-monitoring experiments. (b) Set-up of methods and devices. (c) Active and passive monitoring results concentrating on two extremely-strong radon anomalies (∼ 500 kBq m−3). (e) Discussion regarding the employed ±2σ technique for identifying radon disturbances. (f) Application of wavelet-power-
