Outline of Final Research Achievements

We have conducted problem-fitted studies for effective management of radiation exposure. The specific objectives include measuring, assessing and communicating
individual external doses, cost-effectiveness analysis of decontamination and comparing risk management measures among areas affected by the nuclear plant accidents. The results of our study suggested that although measured external doses vary depending on activity patterns and locations of individuals, the measured external doses were well below the initial estimates by the government.In addition, it was found that the cost of radiation dose reduction measures in Fukushima is considerably higher than that of Chernobyl. The evidence obtained by this study is thought to provide valuable information to consider effective risk measures accepted by public with high scientific rationality.
