The rapidly evolving field of Muography opens an outstanding way to reveal density anomalies inside hill-sized objects. The cosmic muons lose thei energy gradually and penetrate hundreds of meters into the ground, thus their differential local flux correlates with the density-length they traveled through.
In case of underground muography one exploits the low background and the higher flux...

Muon tomography is a non-invasive technique able to scan the internal density of large structures. This technique infers the density of an object by tracking the number of muons received by a detector, before and after traversing a structure. The amount of density met by a muon on its path minimizes its survival probability in a predictable manner, hence diminising the average flux received by...
