High-resolution imaging of nuclear waste containers with muon scattering tomography

Muon scattering tomography is a non-invasive technique that can be used to scan large containers and search for high-Z materials. This is of particular interest to characterise large volume legacy nuclear waste. Here we detail a method that allows to measure the size of high-Z objects embedded in concrete using muon scattering tomography. The resolution obtained was of 0.9 ± 0.2 mm.
