The accident of the Fukushima Daiichi Nuclear Power Station (hereinafter referred to 1F), Tokyo Electric Power Company Holdings, Inc. occurred due to the Great East Japan Earthquake, Sanriku offshore earthquake, of 9.0 magnitude and the accompanying tsunami. As a result, large amount of radioactive materials was released into the environment. Under these circumstances, JAEA has been conducting Long-term Environmental Dynamics Research concerning radioactive materials released in environment, especially migration behavior of radioactive cesium since November 2012. This report is a summary of the research results that have been obtained in environmental dynamics research conducted by JAEA in Fukushima Prefecture.

The impacts of oxygen in rhizosphere on the symbiotic nitrogen fixation in real-time was evaluated under various O$$_{2}$$ partial pressure. Soybean nodules were treated with mixed gas containing N$$_{2}$$ labeled with a radioisotope $$^{13}$$N and various concentrations of O$$_{2}$$, and the nitrogen fixation activity in the nodules was visualized by the positron-emitting tracer imaging system (PETIS). The results showed that under normal condition the nitrogen fixation ability of soybean plant was higher compared to that of under the other conditions (0% O$$_{2}$$ and 10% O$$_{2}$$). There was no significant difference in the nitrogen fixation activity between 0% O$$_{2}$$ and 10% O$$_{2}$$.
