Establishment of regeneration scheme for post nuclear accident: based on analysis of the Fukushima Daiichi nuclear accident
This is a policy-focused research for structuring a ‘recovery plan’ as a countermeasure for aftermath of a nuclear accident. It analyses the meta-data gathered from monitoring the Fukushima Daiichi nuclear accident and draws lessons from it. The report is the first-year research out of three and this year, it focuses on the analysis of the environmental and social meta-data from the monitoring data and corresponding actions of the Japanese government. The main findings are as follows.

Environmental Impacts of the Fukushima Accident
After the accident, all surroundings of Fukushima Nuclear Power Plant have been affected but are currently under recovery. First, as for the ‘atmosphere’, radioactive materials, such as Cs-137, have deposited un-proportionately by mountains, wind and precipitation. Second, in case of ‘forest’, the litter and the surface soil layer have absorbed high levels of Cs-137, resulting in slow discharge progress so far. On this account, it is hard to reduce the degree of the space dose in a way that the total radiation dose is equal to as hitherto. Third, when it comes to ‘soil’, especially in the case of uncultivated land, radioactive materials remain 5cm under the surface. As in the following, rivers and the lakes show no signs of radioactive detection at any monitoring posts, because the substances have subsided. Constant monitoring is carried out to detect changes in Cs-137 level caused by opaque water in the events of heavy rainfall. Next, ‘groundwater’ is intact for now, however, the real problem occurs when it passes the reactor building, which m
