Simulation for material discrimination and identification using multiple scattering muon tomography

Highly penetrating cosmic ray muons shower the Earth at the rate of 10,000 m^-2 min^-1 at sea level. The mean energy of muons at sea level is about 3–4 GeV, sufficient to penetrate several meters of rock(Avg ρ ≈ 2.6). Due to their highly penetrating characteristics, they can be used for radiographic imaging of dense material. Using this freely available particle to detect the high Z material is very useful for homeland security application related to Shielded Nuclear Materials (SNMs). In this paper we will show the result of Geant4 simulations to discriminate and identify homogeneous material using multiple scattering of muons of 3 GeV
