WASHINGTON (Xinhua): "Not one drop" of Japan's Fukushima radioactively contaminated water should be released until the world is convinced that the water has been treated to remove nuclides to "non-detectable levels", a prominent US marine conservation biologist told Xinhua in an interview on Wednesday (April 21).

The Japanese government announced last week it had decided to discharge contaminated radioactive wastewater in Fukushima Prefecture into the sea.
