Fukushima nuclear isotopes found in Californian wine
The nuclear disaster at the Fukushima power plant in 2011 has led to a spike in levels of a radioactive isotope in Californian wines, scientists say. An increase in the levels of caesium-137 has been identified in several different wines by specialists from the University of Bordeaux in France, who say levels doubled in 2011.Affected red and rosé wines showed different levels of the isotope, which has been released into the atmosphere by nuclear accidents and weapons tests, with darker wines collecting more of it.They are all far below the threshold believed to cause radiation sickness in humans, but show how the material from the Fukushima disaster spread.Historical nuclear events have also led to much higher levels of the radioactive isotope, with levels peaking roug...
