Results of the monitoring on radioactivity level in fishery products
|
In accordance with the “Concepts of Inspection Planning and the Establishment and Cancellation of Items and Areas to which Restriction of Distribution and/or Consumption of Foods concerned Applies” the Fisheries Agency, in cooperation with the relevant prefectural governments and organizations, has been regularly conducting monitoring of radioactive materials in the fishery products at the major fishing ports in Fukushima and adjacent prefectures since the accident of Fukushima Daiichi Nuclear Power Station (FDNPS) of Tokyo Electric Power Company following the Great East Japan Earthquake in 2011. |
At a total of 179,446 fishery product samples has been monitored (as of July 29, 2022) since the FDNPS accident. The result represents a significant trend that the radioactive cesium excess ratio has decreased and recently very few fishery products exceed the Japanese maximum level (100Bq/kg). Shipment restrictions have been lifted for the great majority of marine fish species and thereby they are traded at the market without any radiological restrictions in Japan.
