Numerical Simulation of Radial and Angular Distribution of γ-Ray’s Energy Deposition in Scintillation Optical Fibre

【摘要】 <正> Angular and radial distributions of the energy deposition of γ-ray radiation in scin-tillation optical fibres are simulated and analysed using the Geant4 system.The results showa linear relation between the energy deposition and the radius of the fibres.The deposition isroughly inversely proportional to sinθ with θ the incident angle relative to the fibre axis.Theresults could provide corrections to the measurements of the scintillation fibres used in monitoringthe γ-ray radiation.更多还原
