内容記述 | To investigate a radiobiological effectiveness of radioactive heavy ion beams that produces excess low energy delayed particle at the stopping position of the beam, we obtained a radioactive beam and performed radiobiological experiments. We obtained 9C beam from a 430 MeV/u 12C beam with Be target in the secondary beam line at HIMAC. The production characteristics of 9C beams have been investigated and the optimal conditions to produce the beam with higher production rate and purity were found. A spot scanning system was used to deliver the ions to cell samples having an uniform irradiation field. Radiobiological experiments have been carried out for the beam with low intensity (0.3-0.5 Gy/h). HSG cells were placed at different depths, i.e. different LET along the penetration of the beam, and irradiated with the beam. Survival curves were obtained by a colony forming assay and the RBE values to the similar dose rate gamma-ray was calculated. higher RBE for the beam at the depths around its Bragg peak (at around 80 keV/um) than 12C high dose rate beam have been revealed. |
