We cultivated wet rice on the paddy field contaminated by radioactive cesium in Minamisouma city. We evaluated the effects of fertilization of a zeolite and a potassium manure on a transfer factor of radioactive cesium to the cultivated rice.

This paper outlines agricultural approaches of remediation activity in contaminated areas outside of the Fukushima Daiichi Nuclear Power Plant. About the decontamination examination of contaminated areas, we have tried the land scale test of a rice field before and after planting by the use of currently recommended methods. For the radioactive nuclide migration control of rice by wet rice production, several types of decontamination methods such as zeolite addition and potassium fertilization in the soil were examined, and investigated the validity of the cesium migration control for the brown rice by the combination of those methods.
