The radioactive decontamination of paddy fields is desired to maintain the fertile state of rice paddies that will be passed on from one generation to the next. Prefectural and municipal governments are giving advice on contamination through the ploughing in of rice straw and the spreading of zeolite onto the fields; however, there are problems such the accumulation of pollutants and the ruining of the paddy fields, so the problem is stagnating. This project is carried out in collaboration with the Shimooguni District Council of Fukushima Prefecture that has has until now been working on this problem independently. The project involves the use of bamboo charcoal and other absorbent materials during the puddling of the paddy fields, to reduce the levels of radioactive cesium in the paddy field soil by making the removal of the cesium more efficient, to enable rice cultivation to resume and to revitalize the local community.
