摘要：

An accelerator-based boron neutron capture therapy (AB-BNCT) system was installed at the Shonan Kamakura General Hospital (SKGH). We confirmed that a stable operation was possible for 1 h at a current of 30 mA. The evaluated thermal neutron flux was 2.8 x 109 cm-2 s- 1 and in good agreement (& PLUSMN;5%) with the calculated values. The daily variation was within & PLUSMN;2%. The ambient dose rate due to residual radioactivity after irradiation was approximately 5 & mu;Sv/h using a lead shutter.
