福岛核事故是由极端外部事件叠加,即超强地震与超高海啸共同作用,导致全厂断电而引发的群堆共模严重事故。福岛核事故为INES-7级,向大气中释放的放射性物质中131I和137Cs分别达到1.6×1017Bq和1.5×1016Bq,向海洋中释放的放射性物质137Cs达到1015Bq。核事故造成了短期内大量灾民撤离和避迁,农产品、食品、海产品和渔业遭受严重影响,旅游业受到显著影响,核电行
The Fukushima nuclear accident was caused by the superposition of extreme external events, that is, the combined effect of the super-earthquakes and the ultra-high tsunami that led to the mass-reactor common-mode serious accidents caused by the power failure of the whole plant. The nuclear accident at Fukushima was INES-7, and 131I and 137Cs released into the atmosphere reached 1.6 × 1017Bq and 1.5 × 1016Bq, respectively, and 137Cs released to the oceans reached 1015Bq. The nuclear accident caused a large number of victims to evacuate and evacuate in a short period of time. The agricultural products, foodstuffs, seafoods and fisheries were severely affected, the tourism industry was significantly affected, and the nuclear power bank
