(Provisional Translation) the Monitoring Results on Radioactive

(Provisional translation)

The monitoring results on radioactive materials in fisheries products produced in Hokkaido

The Hokkaido Government has been monitoring the level of radioactive materials in fisheries products landed at Hokkaido ports to confirm their safety. The results of the monitoring show that the radioactivity level was either Not Detectable or lower than the Provisional Regulation Value, established by the Government of Japan.

* “< __” in the table below indicates that the measurement value is below the detection limit. The results that were provided without the information on detection limit appear as “Not detectable” on the table instead.
