Abstract
A plastic scintillating fiber capable of reducing modal dispersion and improving the accuracy of identifying a position which radiation passes through. A plastic scintillating fiber includes a core and a cladding that covers an outer periphery of the core and has a lower refractive index than the core. The core uniformly contains a radiation-emitting fluorescent agent and has a refractive index distribution where the refractive index of the core is highest at a center of a cross-section and becomes lower in a parabolic manner with distance from the center toward an outer periphery.
