Identification Of Material Using Muography

Abstract

Muography is an imaging technique based on the absorption or scattering of atmospheric muons produced from cosmic-ray interactions in the atmosphere. These muons are abundant at sea level and thus provide a natural source for imaging. Scattering density is a characteristic of matter that can be used to discriminate between different materials. When muons pass through material they produce an aggregate of scattering angles with an approximately Gaussian distribution. The standard deviation of the distribution can be calculated using the radiation length of the substance. In this study, we calculate the scattering densities for 20 elements at different four values of the momentum of the muons to show the dependency on the momentum of the incident muons. Our results presented in this study complete the results obtained in some previous related studies.
