Abstract
A plastic scintillating fiber includes an organic compound containing an element with a neutron cross section larger than that of hydrogen, and includes: an outermost peripheral layer containing a plastic material that emits scintillation light when it is irradiated with neutron radiation; a core having a high refractive index, disposed inside the outermost peripheral layer, and containing at least one type of fluorescent substance that absorbs the scintillation light and wavelength-converts the absorbed light into light having a wavelength longer than that of the absorbed light; and a cladding layer covering an outer peripheral surface of the core and having a refractive index lower than that of the core. A wavelength shifting fiber including the core and the cladding layer, and the outermost peripheral layer covering an outer peripheral surface of the wavelength shifting fiber are integrally formed.
