Initial evaluation of accelerator-based neutron source system at the Shonan Kamakura General Hospital
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 × 109 cm−2 s−1 and in good agreement (±5%) wit...

| description | 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 × 109 cm−2 s−1 and in good agreement (±5%) with the calculated values. The daily variation was within ±2%. The ambient dose rate due to residual radioactivity after irradiation was approximately 5 μSv/h using a lead shutter.
•The Neutron Source System at Shonan Kamakura General Hospital was presented.•Stable operation was possible at a current of 30 mA.•The maximum thermal neutron flux was over 2.8 × 109 cm−2 s−1.•The ambient dose rate after irradiation was approximately 5 μ Sv/h at a position 1 m from the beam aperture. |
