 note = {We have begun to investigate cellular bystander responses in normal human fibroblasts induced by microbeams of different radiation types. This year, we used two different microbeams, such as carbon ions as high-LET (Linear Energy Transfer) radiations and X rays as low-LET radiations. Carbon-ion microbeams ((12)C(5+), 220 MeV) were generated with the Takasaki Ion Accelerators for Advanced Radiation Application (TIARA) at Japan Atomic Energy Agency. Mono-energetic X-ray (5.35 keV) microbeams were produced with the Photon Factory (PF) at High Energy Accelerator Research Organization. We designed that only 0.2 percent of total cells was irradiated with each microbeam. The percent cell survival in microbeam-irradiated dishes was ranging from 83 percent to 94 percent for carbon ions, while around 100 percent for X rays. Mutation frequency for carbon-ion-microbeam irradiated cells was about 6 times higher than that for non-irradiated control cells, but there was no difference in mutation frequency between X-ray-microbeam irradiated and control cells. There is clear evidence that bystander cellular effects induced by low-dose radiations depends on a radiation quality., 資料番号: AA0063706092},
