摘　　要：Fundamental characteristics of the plastic-scintillating fiber (PSF) for wide energy range of electromag- netic radiation (X & γ) have been studied to evaluate possibility of using the PSF as an imaging detector for industrial purposes. Monte-Carlo simulation program (GEANT4.5.1, 2003) was used to generate the data. In order to evaluate image quality of the detector, fiber array was irradiated under various energy and fluxes. Signal to noise ratio (SNR) as well as detector quantum efficiency (DQE) were obtained.Fundamental characteristics of the plastic-scintillating fiber (PSF) for wide energy range of electromag- netic radiation (X & γ) have been studied to evaluate possibility of using the PSF as an imaging detector for industrial purposes.
