福岛第一核电站事故对近岸海域鱼类的辐射影响

Radiation Effects of Fukushima Dai-ichi Nuclear Power Station Accident on Fishies in Offshore Area

利用福岛第一核电站事故后不同沿岸和离岸距离处的海水中放射性核素137Cs的监测数据,以鱼类为参考水生生物,通过核素137Cs的累积动力学模式对鱼体内核素的动态浓集进行了评估,给出了福岛第一核电站事故后液态放射性释放所致近岸海域水生动物体内核素水平的变化规律。

The dynamic modeling of 137Cs accumulation by the fish, as reference aquatic biota species, was developed for evaluating dynamic concentration process, based on monitoring data of 137Cs coneentra tions in the sea water offshore and longshore after the accident at Fukushima Dai-iehi Nuclear Power Station. The dependence of 137Cs dynamic concentration by the fish was provided on 137Cs concentration in the water and fish age.
