A simulation of gamma-ray radar performance with different position sensitive detectors
In the last decade V.E. Radko has introduced the concept of gamma-ray radar for 3D Compton imaging with a probing beam of 511 keV annihilation gamma-rays from positron emitting radioactive sources. The simultaneous detection with 2 position sensitive detectors of direct, non-scattered quanta and second quanta scattered in the investigated object produce information of density distribution or composition of the object. This new type of gamma-ray imaging system for nondestructive testing may have different applications in flaw detection and studying of structure of opaque objects with one side access. The performance of the system was studied with Monte-Carlo simulation.
