Abstract: The Tokyo Electric Company's Fukushima Dai-ichi Nuclear Power Plant accident contaminated a large area of agricultural land with radioactive cesium. If the contamination levels were high, topsoil removal or inversion tillage were the major countermeasures used to decrease the radioactivity of the soil. However, a substantial level of radioactive cesium remained in the soil, even after decontamination and some fields weren't decontaminated. To mitigate radioactive cesium transfer from soil to plant, we tested increasing potassium levels in the soil. In this paper, we demonstrate how we developed these countermeasures in Fukushima.
