Yes, this article is from Greenpeace, but it’s not hyperbolic. Jan Beránek writes:
There have been a number of news stories recently about the radiation escaping into the ocean at the Fukushima Daiichi nuclear power plant that have raised great concern. Some are worried about how escaping radiation may or may not be affecting ocean eco-systems around the world.
Since Greenpeace has been working on the Fukushima nuclear crisis since it first began in March 2011, we can offer some thoughts on people’s concerns.
We have sampled sealife along the Japanese coastline, both from the Rainbow Warrior and in conjunction with local fishermen and Japan’s food cooperatives.
You can find some of the results of our independent measurements on our Radiation Surveys – Fukushima webpage.
While we don’t have a marine biologist on our team, we have a number of radiation specialists whose findings and assessments we share with scientists and academic researchers.
