Outline of Final Research Achievements

In this study, biological effects on the cells exposed to ionizing radiations such as X-rays were investigated based on the microdosimetric-kinetic model considering cell cycle and the experimental results for cellular damage. The parameters in the model were determined by comparisons with related quantities from the experiments.
It was shown that the model associated with amounts of DNA and repair probability of its damage enables us to reproduce properly the cell surviving fractions for various dose-rates and radiation energies. Further, non-targeted effects through intercellular communication (medium transfer bystander effects) and low-dose hyper-radiosensitivities were demonstrated by taking advantage of extensibility of the model.

Academic Significance and Societal Importance of the Research Achievements

生体組織へ電離放射線が及ぼす影響について、局所的な放射線エネルギー付与や線量率、細胞周期に依存するDNA量とその損傷・修復率といった因子を、微視的線量と損傷動態を考慮するMKモデルに基づいた細胞生存率の式に組み入れることができた。
放射線被ばくに関わる種々の現象量(パラメータ)を細胞実験による実測に即して決定すると共に、モデルを適切にカスタマイズすることによって、MKモデルが多くの細胞生存率の結果を忠実に再現しうることを明らかにした。これにより、放射線の生物学的影響がもたらされる機序を定量的に推定することが可能となった。
