Japan says it has found traces of radioactive caesium in two whales harpooned off its northern shores.
The two minke whales were recently harpooned off the island of Hokkaido.
The country’s fisheries agency says low levels of radioactive caesium were found in the whales, adding they may have been contaminated by the crippled Fukushima nuclear plant which has been leaching radioactive material into the Pacific.
The agency says the level of contamination in the whales is far below Japan’s maximum safe limit for marine products.
