Cosmic-ray borehole muography is a novel imaging method that detects density variations in soils and underlying rocks. The method can be compared to X-ray imaging as the physical principles of both methods are similar. However, whereas X-ray imaging works only with small objects due to relatively low energies of X-rays, muons can have enormous energies and are therefore much more penetrative particles. In fact, the difference in the maximum penetration between these two types of radiation is three magnitudes.

Muon Solutions develops borehole muography for mineral and mining sector. We are financially supported, among others, by EIT RawMaterials. Read more about us from their News section for SME Booster program funded Start-ups at

Muon data are recorded by borehole probes. The data are constructed on an muon-by-muon basis and are thus statistical. The statistical data are then translated to relative density information that is meaningful for geoscientists.
