In this report, several works on mainly resuspension and eolian transfer of radioactive cesium due to wind, which is one of the most effective transfer processes of previously deposited radioactive particulate materials, are introduced. First, the mechanisms of the resuspension of particulate matter by wind as well as resultant dust storms and wind erosion are surveyed. Next, the papers related to resuspension and eolian transfer of radioactive aerosols originally emitted by the Chernobyl nuclear accident are reviewed. The measured fallouts and radioactivity concentrations show annual cycles, and their peak periods depend on the measured regions. Finally, the works that analyze the related effects of the accident at the Fukushima Daiich Nuclear Power Plant are reviewed, and some issues to be focused and resolved are summarized.
