研究发现 加州红酒放射性水平有所上升
Radioactive levels are increasing in wine from California's Napa Valley, thanks to the radioactive cloud that drifted from the Fukushima nuclear disaster in 2011. Researchers from the University of Bordeaux Centre d'Etudes Nucleaires de Bordeaux-Gradignan in France tested California wine from before and after the Fukushima disaster and found there was double the amount of cesium-137 in its Cabernet Sauvignon after the 2011 tsunami caused the Fukushima Daiichi nuclear reactors to leak. The radioactive cloud released by the plant drifted all the way to California's Napa Valley. There, trace amounts of cesium-137 made its way into the vineyard grapes. The levels varied depending on the wine, researchers found, with Cabernet Sauvignon reds having a higher amount and rose having the least. Ingesting cesium-137 can result in an elevated risk for cancer, but the researchers said the levels in the wines tested don't pose a health hazard. The California Department of Public Health said that it had not previously heard of the study, but that there were no "health and safety concerns to California residents." |
