摘要：The radioactive environmental contamination that resulted from the Fukushima Daiichi nuclear power plant accident has clearly been declining during the nearly 10 years that have passed since the accident. Many studies, however, have indicated prolongation of radioactive contamination in natural ecosystems, probably arising from non-decontaminated forested areas, so a more detailed examination is needed on the environmental dynamics of bioavailable radiocesium and its transfer to ecosystems. Also, regarding the influences of radiation on organisms, the effects on wild organisms of the evacuation of humans have been more pronounced than the direct effects from radiation, especially in the Fukushima evacuation zones.
