Radiation-resistant optical fiber/scintillator system for gamma-ray monitor

“…Therefore, it is necessary to take into account the radiation-induced effect when this optical fiber/scintillator system is used as the radiation monitor in high-radiation environments. An optical fiber/scintillator system that uses a plastic optical fiber (POF) [1][2][3] or a conventional quartz fiber [4][5][6] has been developed for radiation detection. These optical fibers generally have a low radiation resistance, and the optical transparency degrades easily in high-radiation fields.…”
