| 内容記述 | According to the 10 years environmental monitoring by TEPCO, as shown in Fig. 1, the radiocesium concentrations in rockfish and some flounders were higher among fish collected from the same port area of the Fukushima Dai-ichi nuclear power plant. Overall examination by radio-ecological model with ecological study, demonstrated that the determining factors of the level in the rockfish were the exposure to the initial contaminated seawater at close to the power plant by its sedentary, followed by depuration delay by sloe metabolism, and survival of contaminated fish by its long life-span (>20 years). However, the radiocesium concentrations in above two fish species decreased below the seafood safety regulatory level of 100 Bq/kg after 2015, and became lower than 10 Bq/kg at 10 years after the accident. | |||||
