Cosmic-ray muons, a type of elementary particle, possess high penetration power and can traverse up to several kilometers of material. By measuring the attenuation of muon flux as they pass through matter, it is possible to non-destructively visualize internal density contrasts—a technique known as cosmic-ray muon imaging. This innovative method enables the imaging of internal structures in large artificial or natural objects that are too thick to be investigated using conventional radiation.
In this presentation, we introduce not only our pyramid exploration using nuclear emulsion detectors for muon imaging, but also our recent research and development efforts aimed at practical applications. These include internal diagnostics of large trees, structural integrity assessments of civil and stone structures such as river embankments and castle walls, investigations of underground cavities related to road collapse, and exploration of subsurface metal ore deposits.
