| Outline of Final Research Achievements |
The current system of radiological protection is uniformly established to the public, and it is important for the radiation risk communication to evaluate the individual radiosensitivity. We studied radiation-induced micronucleus formation in peripheral blood lymphocytes from normal individuals, and found that individual differences of radiosensitivity exist in human populations. We also found that cells from the heterozygous carriers for radiation hypersensitive disorders exhibited an increase of micronucleus formation, suggesting that the DNA repair gene variants are indeed involved in individual radiosensitivity.
