Development of a Cosmic-ray Muon Radiography System with Plastic Scintillators

Abstract

We demonstrate that cosmic-ray muon radiography is viable for detecting high-Z material. While the health risks from radiation and the cost for better image quality, areserious concerns in envertional radiography cosmic-ray muon radiography is free from radiation risk and is good for three-dimensional imaging. Our simulation study supports the ability to reconstruct high-Z material objects with cosmic-ray muons. We also developed a small-scale muon radiography system with plastic scintillators. The large angular deviation from multiple scattering through a test Pb block shows the feasibility of the cosmic-ray muon radiography system.
