Radioactive contamination of vast area including crop land with a focus on  TEPCO Fukushima Daiichi nuclear power plant accident in March 2011, still ask farmers to inhibit the uptake of radioactive material to the crops in the farmland even today a lapse of two years. In this poster, removal technology from the surface soil layer of radioactive cesium  in paddy and upland soils, potassium fertilizer application and mainly zeolite material dressing to reduce the uptake of radioactive cesium to the edible part of plant? All studies are efforts to reduce the concentration of radioactive substances in food less than  standard value. Furthermore, it should be mentioned that not only for the food contamination, but also it should be paid the attention to reduce the radiation exposure of farm workers. In the poster, not only the technical procedures but also obtained results of actual decontamination process in the farm which have been carried out in the contaminated area will be presented.
