Geant4 investigation of the alpha-beta-gamma detector system used in medical imaging, environmental and nuclear site monitoring

No commercially available detector system can measure alpha, beta and gamma-rays at the same time separately with good efficiency, while being cost-effective, portable offering real-time monitoring. The main purpose of an alpha-beta-gamma would be for safety management nuclear decommissioning in industry. This idea a became more valuable, after Fukushima Japan, because waste contain fission products transactinide materials which not only emit but also alpha particles some cases, neutrons. In this research, we investigated best radiation their optimum thickness by using Geant4 based GATE simulation. work revealed better efficiency result each type than previous work. simulation, 0.05 mm ZnS(Ag), 3.2 plastic scintillator 1.75 BGO were found to detection identification respectively. medicine, could modify become miniaturized radio-guided surgery beta-gamma probe beside modification into robotic surgery. research will influence three different areas imaging technology, homeland security
