Outline of Final Research Achievements

In this study, we examined the use of rapeseed for activating the agriculture in the Tohoku region. We conducted a survey to study at three locations of rapeseed cultivation farmland of Minamisoma and katsurao of Sendai, Miyagi Prefecture, Fukushima Prefecture.We have investigated the trend of radioactive material by the sampling of soil and plants. With respect to radioactive cesium dynamics and rapeseed cultivation, it was found that three of fact.Rapeseed to a certain extent absorb radioactive cesium in the soil.When extracting the oil by oil extraction from rape seeds, cesium hardly shifts in oil. It is concentrated in remaining focused in the remaining. In the case of cultivating rapeseed in were decontaminated area can be said to be safe. As a result, in the radioactive cesium contaminated areas, there is no problem in rapeseed cultivation if decontamination is complete.
