Anomalous radon emanation linked to preseismic electromagnetic phenomena

Anomalous emanation of radon (<sup>222</sup>Rn) was observed preceding large earthquakes and is considered to be linked to preseismic electromagnetic phenomena (e.g. great changes of atmospheric electric field and ionospheric disturbances). Here we analyze atmospheric rad...
