Air dose rates in urban areas decrease faster in residential areas than in evacuation zones. This suggests that human activities facilitate the reduction. However, since human activities include various factors such as decontamination and road wear caused by traffic, it is difficult to evaluate the effect of human activities by conventional analysis using monitoring data, except for the effect of decontamination. Then, this series of studies aim to evaluate the effects of human activities on the reduction. Among the series presentations, this one focuses on correlations between population dynamics characterized by mobile phone GPS information and ecological half life decays of air dose rates measured by KURAMA over a wide area with long-term monitoring using LASSO scheme.

However, human activities include various factors such as decontamination and road wear caused by traffic. Therefore, it is difficult to evaluate the effect of human activities by conventional analysis using monitoring data, except for the effect of decontamination. This study aims to evaluate the effects of human activities on the reduction. This study has been analyzed using air dose rate monitoring data obtained over a wide area with long-term monitoring, in addition to the field observation and simulation evaluations. In this presentation, an overview of this study and the results of field observations are present.
