Differentiation between earthquake radon anomalies and those arising from nuclear activities

The present work offers a methodology to correlate the earthquake time, magnitude and location based on the behavior of radon concentration. By correlating tectonic events to radon behavior, based on previously published radon data, radon concentration signals can be taken into consideration in decision making. Three correlations between magnitude, time and epicenter distance are presented. The applicability of any one of them depends on the measurement technique. Moreover, a suggested procedure is presented to determine the possible confusion between signals for radon anomalies originating from tectonic failure and those arising from nuclear activities. The suggested method depends on the change observed on the 219Rn and 222Rn daughters concentration ratios.
