3D imaging of a nuclear reactor using muography measurements. [PDF]

open access: yesSci Adv, 2023
The inspection of very large or thick structures represents one of the biggest challenges for nondestructive techniques. For such objects, a particularly powerful technique is muography, which makes use of free, natural cosmic-ray muons.
