Summary | After the Great Eastern Earthquake, a lot of radioactive material was released from the Fukushima Nuclear Power Plant. As for river managers, it is important to understand the movement of the radioactive material. In this study we collected and analyzed the results or information of the field surveys, researches and technological development on radioactive material mainly conducted by the Ministry of Environment (MOE), Ministry of Education, Culture, Sports, Science and Technology (MEXT), and universities. The results illustrate that concentration of radioactive cesium has correlation with suspended solid (SS) and turbidity, and that of lakes showed higher value than that of rivers. |
