I investigated the repair process of DNA damage with low dose radiation exposure and applied it to α-ray therapy. In this research, I visualized the repair process of DNA damage by glass capillary microbeam irradiation method using Peltron accelerator, and examined biological effects and application of α-ray therapy from statistical analysis.
