  We present the results of a long term, continuous radon monitoring experiment
started in April 2010 in a seismically active area, affected during the
2010-2013 data acquisition time window by an intense micro seismic activity and
by several small seismic events. We employed both correlation and
cross-correlation analyses in order to investigate possible relationship
existing between the collected radon data, seismic events and meteorological
parameters. Our results do not support the feasibility of a robust one-to-one
association between the small magnitude earthquakes characterizing the local
seismic activity and single radon measurement anomalies, but evidence
significant correlation patterns between the spatio-temporal variations of
seismic moment release and soil radon emanations, the latter being anyway
dominantly modulated by meteorological parameters variations.
