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., Fukushima Dai-ichi and the Ocean: 10 years of study and insight}, title = {The determining factors of radio-cesium levels in fish off Fukushima derived from dynamic biological transfer model simulation}, year = {2021} }
