Radiation detector and transmitting device of radiation detecting light

Abstract

Abstract PURPOSE:To make an apparatus simple and inexpensive by a construction wherein a fluorescent scattered light emitted from a scintillator on the basis of incidence of a radiation is subjected to wavelength conversion, condensation and transmission by a fluorescent plastic optical fiber. CONSTITUTION:When a radiation A to be detected enters a radiation sensing emission wavelength converter 1, a scintillator 2 makes emission and outputs a light B. This light B enters a fluorescent plastic optical fiber 5 and a light C of an emission wavelength spectrum being different from the one of the incident light B is excited in fluorescence therein. The excited light C is transmitted through the fluorescent plastic optical fiber 5 and a light D is outputted at an output end thereof. Besides, a microlens 9 as an optical lens is fitted to each output end of the fluorescent plastic optical fiber 5 except an optical filter 7 and a light-transmission optical fiber 10 is connected to the lens. Thereby the light outputted is transmitted to a remote point.
