Radiation Still Leaking Into Nearby Japanese Waters

By Eryn Brown, The Los Angeles Times

28 October 12

 

ore than 18 months after a magnitude 9.0 earthquake, 40-foot tsunami and nuclear power plant woes that struck Japan starting March 11, 2011, levels of radioactive cesium 134 and cesium 137 originating from the crippled Fukushima-Daiichi plant remain elevated in some fish and seafood in nearby waters.

That suggests that radiation from the plant is still being released into the ocean, wrote Ken Buesseler, a marine of the Woods Hole Oceanographic Institution in Woods Hole, Mass., in a perspective article in Friday's edition of the journal Nature.

Buesseler reviewed data on radionuclides in fish and other seafood that have been compiled by the Japanese Ministry of Agriculture, Forestry and Fisheries since March 23, 2011. Cesium levels were highest in bottom-dwelling fish caught near Fukushima prefecture, and lower in fish who live in the open ocean or closer to the surface, Buesseler reported.

He also noted that cesium levels had not declined, except "perhaps" in surface-dwelling fish. Over time, cesium that accumulates in the muscle tissue of fish should decline at a loss rate of a few percent per day. From this Buesseler reasoned that "there must be a continued source of cesium contamination associated with the seafloor." One possibility could be radionuclides from Fukushima lurking in ocean bottom sediments.

The news was not all dire. The "vast majority" of fish near Fukushima, Buesseler wrote, have radioactive cesium levels below the strict limits for seafood consumption adopted by the Japanese government in April 2012 to assuage consumer fears. And fish that migrate out of the area lose their cesium rapidly.As an example, Buesseler cited the example of bluefin tuna caught off the California coast, which carried minuscule-but-detectable amounts of radioactive cesium all the way across the Pacific.

But to fully understand how much radiation is in fish and seafood near the Fukushima Daiichiplant now and in the future, Buesseler added, studying the marine life caught in the area won't be enough: Scientists will also need to learn more about where the cesium near the ocean floor is coming from and how it collects and accumulates.

We are concerned about a recent drift towards vitriol in the RSN Reader comments section. There is a fine line between moderation and censorship. No one likes a harsh or confrontational forum atmosphere. At the same time everyone wants to be able to express themselves freely. We'll start by encouraging good judgment. If that doesn't work we'll have to ramp up the moderation.

General guidelines: Avoid personal attacks on other forum members; Avoid remarks that are ethnically derogatory; Do not advocate violence, or any illegal activity.

Again and again the atomic genie has been released on the people by design or accident. Is anyone thinking out there?

Leaders of the World need to WAKE UP and realize that they are POISONING our Food Supply at a Ferocious rate, not only with the Fukushima Disaster but ALL over our Oceans with their Oil Spills and Toxic Dumps into them. Is it ANY wonder that the Whales are beaching themselves in record numbers? Who could blame them? They are tired of swimming in a Toxic Toilet Bowl! The ReTHUGlicans can deny Science all they want, however, they CAN'T fool with Mother Nature without her leaping up to bite them on their flabby Behinds EVENTUALLY! The "FrankenStorm" about to hit the East Coast is a wake up call for EVERYBODY to sit up and GET BUSY Working on FIXING the ruination we have wreaked on the Earth! We won't have to worry about Sunnis, or Shiites or Al Queda or the Taliban! We're doing a swell job of killing ourselves! Just THINK about it, and while you do, think about never, EVER voting ReTHUGlican!

The genie is unleashed and now roams the food chain. Perhaps forever.

Is it mort incomprehensibl e to fathom that as this disaster continues unabated, both presidential candidates are enthusiasticall y calling for yet more nuclear power plants?

All people care about is "out of sight, out of mind." Give me cheap electricity and cheap oil and gas and do not tell me anything else. You cannot see radation so it is no problem. Cannot anyone remember the 1950s when they tested atomic bombs in Nevada and my state was down wind and half a dozen of the kids in my class died of leukemia. But I guess that is just the cost of progress. Mitt Romney says that global weather change has not been proven. That "clean coal" is the solution to our energy "problmes" The Koch brothers are poring millions into the campaign for Pres so that Mitt Romney will reverse the EPA's madate for coal plants to put scubbers on their smokestakes to remove mercury from the atmosphere. Mercury is just like radiation, you cannot see it so what is the problem? Let your children, breath it, drink it and eat it? Take the restrictions off of industry and let them make money and create jobs!!!!!
