Abstract
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.
>Over the summer in 2015, Guardincerri and her students built a mock-up of the dome's thick inner shell out of radiation-shielding concrete bricks ... After just 17 days, all three iron bars were clearly visible in the resulting image. You can see the iron bars and muon images…
