FIP2. Survey of radionuclide movement with wildlife (English version)

To understand the dynamics of radionuclides in the ecosystem of Fukushima Prefecture, we are studying how radionuclides are assimilated into wild animals, which constitute part of the ecosystem. We measured the concentration of radiocaesium in the bodies and food of wild animals, and analyzed the temporal change and differences among species. Furthermore, having studied the home range of wild animals because the behavior of wild animals is closely related to the dynamics of radionuclides in the ecosystem, we found that the home range of wild boars inside the evacuation zone tended to be larger than that outside the evacuation zone.
