The hydrogeological vulnerability within an archaeological area constitutes a high environmental risk factor for the excavation and safeguard of the historical ruins. Specifically, among the possible scenery due to a conspicuous presence of water, the interception of groundwater and the consequent submerging, even temporary, of the archaeological structures, can damage the monuments, makes excavation very difficult and expensive and sometimes even prevents it.

Understanding natural variations of Rn (222Rn) concentrations is the fundamental
prerequisite of using this radioactive gas as a tracer, or even precursor, of natural processes, including
earthquakes. In this work, Rn concentrations in groundwater were continuously measured over
a seven-month period, during 2017, in the Giardino Spring, Italy, together with groundwater levels
in a nearby well installed into a fractured regional aquifer. Data were processed to reduce noise,
