Outline of Final Research Achievements |
In the present study, we examined the application of novel radiation risk assessment considering not only harmful but benefit effects. A relationship between LPS-induced inflammation and irradiation by X-ray or radon inhalation was analyzed by animal experiment using mouse and biochemical assay. The evaluation with a concept of Taguchi method revealed that there were interactions between inflammation and irradiation, suggesting that further data collection and consideration of analysis method can develop novel radiation risk assessment.

Academic Significance and Societal Importance of the Research Achievements |
東京電力福島第一原発事故後,放射線の生体影響について非常に関心が高まったが,低線量放射線の生体影響についてはまだ明らかになっていないことが多く,専門家の間で議論が続いている。従来の統計学を用いた放射線のリスク評価では,低線量域では高線量被ばく調査から得た推定リスクの外挿になっている。我々の生活に密着する身近な低線量放射線について,生物学的真実を定式化した新規放射線リスク評価法の開発は学術的にも社会的にも意義があるものと言える。
