Abstract

PURPOSE:To reduce size and improve the efficiency of detection by coupling a scintillator in one body to the leading end part of an optical fiber in a radiation detector combined with the scintillator and the optical fiber. CONSTITUTION:A scintillator 22 is buried integrally in the leading end part of an optical fiber 21 consisting of a core 211, cladding 212 and coating 213. The radiation detector of such construction is formed by piercing a hole through selective etching of only the core of the leading end part by, for example, an aq. HF soln. by utilizing the difference in the compositions of the core 211 and cladding 212 of the fiber 21 and burying the scintillator 22 into this hole. NaI(Tl), Bi4Ge3O12, CdWO4, etc. are used as the scintillator 22, and when radiations R are made incident to the leading end part, the scintillator 22 generates light. This light is transmitted by the fiber 21 to a photodetector 23, whereby the information on dose rate, energy, counting rate, etc. relating to the radiations R is analyzed.
