Fukushima’s Radiation Will Poison Food “for Decades,” Study Finds

Three of the six reactors at Japan’s Fukushima-Daiichi complex were wrecked in March 2011 by an earthquake and tsunami. The destruction of emergency electric generators caused a “station blackout” which halted cooling water intake and circulation. Super-heated, out-of-control uranium fuel in reactors 1, 2, and 3 then boiled off cooling water, and some 300 tons of fuel “melted” and burned through the reactors’ core vessels, gouging so deep into underground sections of the structure that to this day operators aren’t sure where it is. Several explosions in reactor buildings and uncovered fuel rods caused the spewing of huge quantities of radioactive materials to the atmosphere, and the worst radioactive contamination of the Pacific Ocean ever recorded. Fukushima amounts to Whole-Earth poisoning.

Now, researchers say, radioactive isotopes that were spread across Japan (and beyond) by the meltdowns will continue to contaminate the food supply for a very long time.

According to a new study that focused on “radiocaesium” — as the British call cesium-134 and cesium-137 — “food in japan will be contaminated by low-level radioactivity for decades.” The official university announcement of this study neglected to specify that Fukushima’s cesium will persist in the food chain for thirty decades. It takes 10 radioactive half-lives for cesium-137 to decay to barium, and its half-life is about 30 years, so C-137 stays in…
