MEASUREMENT OF RADIATION INTENSITY DISTRIBUTION

摘要

PURPOSE:To expand a measuring range and to reduce cost. CONSTITUTION:A photodetector 2 is connected to one end surface of a scintillation fiber 1 and a light reflector 3 is connected to the other end surface thereof. A time interval measuring device 4 and a data analyzing computer 5 are connected to the photodetector 2 on the output side thereof in series. The time interval of the light signal detected by the photodetector 2 is measured by the time interval measuring device 4 and the position and the intensity of the radiation incident on the scintillation fiber 1 are calculated by the data analyzing computer 5.
