综述了福岛核电站事故后放射性铯污染在森林生态系统中的归宿。首先，沉降物污染了森林的地上部分，然后大部分污染物在森林中向下移动，最后积累在土壤的最表层。虽然没有观察到辐射对森林生物的任何严重影响，但土壤生物通过生境和食物受到了污染。土壤生物的摄食习性很好地反映了放射性Cs体内污染的种特异性时程变化。真菌提取放射性铯是利用木屑修复受污染森林地表的一种很有前途的方法。
The fate of radio-Cs contamination in forest ecosystem after the Fukushima Daiichi Nuclear Power Plant accident was reviewed. First the fallout contaminated aboveground part of the forest, and then most of the contaminants moved downward in the forest and finally accumulated in the very surface layer of soil. Although any acute effect of radiation to forest organisms was not observed, soil organisms were contaminated via habitat and food. Feeding habit of soil organisms well reflected species-specific time-course changes in body contamination of radio-Cs. Mycoextraction of radio-Cs is promising method to rehabilitate contaminated forest floor using wood chips.
