In order to detect the radiation sensitivity of tumor cells,the methods of single cell gel electrophoresis (SCGE) and ,3,H—TdR incorporation were applieded to determine effects of radiation on single strand breaks of DNA in K562、SMMC—772 and HOS8603 cell lines. The experimental results proved that the cell migration distance was prolonged,DNA syntheses was restricted and the ,3,H—TdR incorporation rate was decreased in the above—mentioned 3 tumor cells lines after irradiation by ,60,Co ,γ, rays(1—20Gy).
