In this study, plastic optical fiber sensors which can measure thermal neutron dose in a mixed neutron－gamma field are developed and characterized. Using 252Cf and 60Co sources, the scintillators suitable for thermal neutron etection,
are tested and the scintillating lights generated from a plastic optical fiber sensor in the Kyoto University Critical Assembly (kuca) core are measured. Also, the distributions of thermal neutron and gamma－ray are measured in a mixed field as a function of the distance from the center of the reactor core at KUCA and the distribution of thermal neutron is obtained using a subtraction method. Sensitivity of the fiber-optic radiation sensor system is about 0.49 V/mW according to power of the KUCA core and its relative error is about 1.2 %.
