On the Concept of System to Detect Unclaimed Inclusions of Fissile and Radioactive Materials in Hand Luggage and Cargo Trucking

摘要

A concept of a system to detect presence of fissile and radioactive materials in cargo and shipping containers is discussed. High energy gamma-radiography of an object may be used to retrieve information on mass and density distribution within it. Important requirement of such a system is the use of appropriate detectors having fast response and large stopping power to high energy gamma-rays along with comparable yields of scintillation and Cherenkov light. We discuss detection by scintillation materials which can be applied to develop such systems.
