  The authors present here a new method to image reinforcement elements inside
thick structures and the results of a demonstration measurement performed on a
mock-up wall built at Los Alamos National Laboratory. The method, referred to
as "multiple scattering muon radiography", relies on the use of cosmic-ray
muons as probes. The work described in this article was performed to prove the
viability of the technique as a means to image the interior of the dome of
Florence Cathedral Santa Maria del Fiore, one of the UNESCO World Heritage
sites and among the highest profile buildings in existence. Its result shows
the effectiveness of the technique as a tool to radiograph thick structures and
image denser object inside them.
