In this work, the dielectric characterization of pietra gentile (a kind of stone typically found in Cul-tural Heritage structures in Southern Italy) was carried out. Measurements were performed for increasing level of water content of the pietra; thus identifying, empiri-cally, the relation between moisture content and dielec-tric permittivity. The obtained laboratory results can be used to derive moisture content/dielectric permittiv-ity calibration curves that could be used, in practice, for noninvasive on-the-field moisture monitoring of pietra gentile-made Cultural Heritage structures. For exam-ple, it would be possible to use the obtained calibration curves with non-invasive measurement systems, such as time domain reflectometry in conjunction with anten-nas, coaxial probes, or waveguides apertures.

The obtained laboratory results can be used to derive moisture content/dielectric permittiv-ity calibration curves that could be used, in practice, for noninvasive on-the-field moisture monitoring of pietra gentile-made Cultural Heritage structures.
