Traces of radioactive waste from 2011 Fukushima nuclear power plant accident has been recently spotted in a California wine by a group of French nuclear physicists. On testing 18 bottles of California’s rosé and cabernet sauvignon produced in 2009 and onwards, it was found that wines produced after the disaster had increased levels of man-made radioactive particles. Two methods have been used by researchers to look for traces of a radioactive isotope called cesium-137. While the first method detects the particles through the wine bottles without having to open or destroy them, the second and the more accurate method for detection is to destroy the wines through heating and reducing them to ashes.Cesium-137 is then tested in those ashes. Inspite of the detection, the experts, according to the New York Times, have assured that there is nothing to worry about health because of the increased levels of radioactive waste in wines.
