Performance testing of the neutron flux monitors from 10Â keV to 1Â MeV developed for BNCT: A preliminary study

The neutron flux monitors from 10 keV to 1 MeV designed for boron neutron capture therapy (BNCT) were experimentally tested with prototype monitors in an appropriate neutron field produced at the intense deuterium-tritium neutron source facility OKTAVIAN of Osaka University, Japan. The experimental test results and related analysis indicated that the performance of the monitors was good and the neutron fluxes from 10 keV to 1 MeV of practical BNCT neutron sources can be measured within 10% by the monitors.
