Atmospheric muons for non-invasive research at the Palazzone Etruscan necropolis in Perugia (Italy)(*)

. - Through a measurement of atmospheric muons transmission in matter it is possible to study the internal structure of objects in terms of average density. The technique is called "transmission muography" and represents a real imaging technique that allows, in a non-invasive way, to identify and locate any anomalies within the structure studied. In this work, an application of the transmission muography technique to an Etruscan necropolis for the non-invasive search of unknown tombs will be presented. The technique was applied to an area of the Palazzone from a single muographic measurement, important information on the presence and location of possible others underground tombs.
