Japan’s radioactive leaks to Pacific Ocean make it imperative to get international help

Nuclear error   Japan should bring in international help to study and mitigate the Fukushima crisis. Nature, 03 September 2013 The radioactive water leaking from the site of the wrecked Fukushima Daiichi nuclear power plant in Japan is a stern reminder that we have not seen the end of the world’s largest nuclear crisis since the Chernobyl meltdown in Ukraine in 1986……..

The most important impacts of the leaks will be those on the sea off Fukushima and the larger Pacific Ocean, which must be closely monitored. After assessments by US and Japanese scientists in 2011 and 2012, two major questions remain unanswered. How much radioactivity is still entering the sea? And, given the high levels of radioactivity that have been measured in some species long after the accident, when will fish and seafood from the region be safe to consume? The leaks make it more urgent to find answers to these questions.

To make reliable assessments of any environmental effects, scientists need to be able to collect data on contamination of marine food webs with all long-lived radionuclides, and particularly with caesium-137, strontium-90 and plutonium-239. They also need to know the sources of contamination, and to study the transport of radionuclides in groundwater, sediments and ocean currents. Current Japanese Prime Minister Shinzo Abe and his government have promised to boost science; they should encourage and support researchers from around the world in collecting and sharing information. Chernobyl was a missed opportunity for post-accident research — in that sense at least, Fukushima could do much better. http://www.nature.com/news/nuclear-error-1.13667
