Changes in Inspection Results for Rice (Incl. Inspection of All Rice Bags)
The production and distribution of rice are managed through measures to inhibit radioactive cesium absorption by the use of potassic fertilizer (p.67 of Vol. 2, "Measures for Reducing Transfer of Radioactive Materials to Crops (2/5) - Measures to Inhibit Radioactive Cesium Absorption through Potassic Fertilization -") and inspection of all bags of harvested rice. In Fukushima Prefecture, planting has been restricted and measures to inhibit radioactive cesium absorption have been taken at former Areas under Evacuation Orders and distribution of rice has been strictly controlled through inspection of all rice bags since FY2015 based on the "Policies on Planting of Rice."
Rice containing radioactive cesium at a level exceeding the standard limit decreased year by year, and there has been none since FY2015 (as of the end of December 2020). This standard limit refers to 100 Bq/kg, which has been applied since April 2012 (in FY2011, provisional regulation values were applied, but tabulation is based on the current standard for the purpose of comparison with the results in and after 2012).
