Outline of Final Research Achievements

The purpose is to examine effective utilization methods of the environmental radiation database that has been accumulated environmental data since the 1950s by considering as "Big Data". For the cause of diurnal change in air dose rate, we performed periodic identification by Fourier analysis and cross analysis of its intensity distribution and meteorological conditions. It was found that the correlation with wind is stronger than that of rainfall, and that there are many diurnal changes in the vicinity of inland areas. We also investigated the correlation between the air dose rate and the nuclear test in the atmosphere by China. In order to grasp the emergency situation, the increase and decrease of the air dose rate was comprehensively investigated nationwide, and the introduction of the moving average of time series data showed the possibility of connecting to a system that issues an alarm regarding the arrival of radioactive fallout from foreign countries.

Academic Significance and Societal Importance of the Research Achievements

これまで、放射性物質の環境動態は特定の数点での測定結果をもとに、日変化や年変化の要因が議論されてきた。60年間蓄積されたこれらのデータを気象データなどと網羅的に解析することで、これまでの知見の確認ができること、また、さらなる新しい知見が得られることを示した。さらに、解析に工夫を加えることにより、隣国で起こるかもしれない緊急事態への備えとして、住民の居住地近傍の放射線モニタリングが有用であるかもしれないことを示した。
