Fundamental characteristics of a new plastic scintillation fiber (PSF) has been studied for four kinds of radiations, and the possibility of using the PSF as a radiation detector has been discussed. Irradiation experiments of scintillation output characteristics have been made for γ rays, x rays, fast neutrons, and α particles. Various scintillation pulse height spectra have been obtained, depending on the variations of radiation types, energies, intensities, and scintillating positions on the PSF. Position detection experiments have been also made for γ rays and fast neutrons, and a new position sensitive detector of the PSF has been proposed.read more

TL;DR: In this article, a novel approach to the fabrication of an optical sensor, sensitive to two separate atmospheric conditions, but made from a single fibre optic, is described, where the optical fibre is drawn from polycarbonate, with a temperature-sensitive phosphor (La2O2S:Eu3+) incorporated directly into the core.

Neutron radiation distribution sensor using flexible plastic scintillating fiber combined with the time-of-flight technique
TL;DR: In this paper, a long fiber system has been made using two silica fibers connected to both ends of the plastic scintillating fiber (PSF), its basic properties were investigated to detect the position of neutron incidence with the time-of-flight (TOF) method.

The feasibility of using plastic scintillation fibers for fast neutron spectrometry
TL;DR: In this paper, the response functions of a plastic scintillation fiber for a fast neutron beam have been studied in detail using Monte Carlo technique, and the efficiency and resolution of a bundle of 100 square fibers at thickness of 0.25 mm are estimated at (4.2±0.2)×10−5 cm2 and (8.7± 0.1)%, respectively.
