Outline of Final Research Achievements

In order to measure an epithermal neutron spectrum near 1keV of BNCT irradiation fields, we have developed a neutron detector based on fluoride-containing bonner sphere. The applicability of the detector was verified by experiments in the epithermal neutron field. To optimize patient exposure dose, a technology with small neutron detectors using optical fibers have also been developed. In the development, the degradation of the optical fiber of the real-time neutron detector was measured firstly, and based on the results, a real-time neutron detector having a radiation resistant property was fabricated.
