Lake Close to Fukushima Nuclear Disaster Could Stay Radioactive For Another 20 Years

The cleanup from the Fukushima nuclear accident in 2011 would cost hundreds of billions of dollars, but the environmental cost might be far greater, according to research, with neighboring lakes polluted for another 20 years. Lake Onuma on Mount Akagi might be polluted with radioactive cesium-137 (137CS) for up to 30 years after the unfortunate incident, according to a group of researchers led by those from the University of Tsukuba.
