摘要

<正>A β-delayed particle decay beam like 9C has been recognized as a double irradiation source, i.e. the external beam radiation itself and the delayed low-energy particles emitted internally. A radioactive 9C-ion beam, therefore, is considered to be very useful in cancer radiation therapy. To explore the potential importance of radioactive 9C-ion beams in cancer therapy, radiobiological experiments using a 9C beam supplied by the secondary beam line (SBL) at the Heavy Ion Medical Accelerator in Chiba (HIMAC), Japan were carried out.
