Muon_tomography_shadows

Detectors are deployed down drill holes from surface and in underground mine workings. Detectors are positioned at varying depths beneath the target zone of interest, capturing incoming muons as they pass through the subsurface. Each sensor captures the directional intensity of incoming muons within a field of view larger than 120°, imaging upwards towards the surface. Denser features attenuate or block muons as they arrive, casting a muon shadow on the sensors. Less-dense features result in more muons passing through, creating an elevated flux of muons along those directions. CREDIT: IDEON TECHNOLOGIES
