| Research Abstract |
To analyze molecular mechanism of the radiation effects at the cellular scale, we have been developing micron size alpha source optimized for single cell-targeted irradiation experiments. Highly purified Po -210 was attached onto the tip of the platinum fine wire and this micro alpha source was manipulated in the vicinity of the targeted single cell. We have performed the single cell-focused irradiation by using the human cultured cells and succeeded in the time-lapse fluorescence imaging to observe DSBs-formation in response to alpha tracks.
