Japan's Fukushima water release safe, says IAEA chief Grossi

The UN's nuclear watchdog chief Rafael Grossi said that Japan's release of treated nuclear wastewater from Fukushima into the Pacific is safe, 12 years after a tsunami knocked out three reactors in one of the world's worst atomic accidents. 

Rafael Grossi, Director General, International Atomic Energy Agency said "The release of water started last week, the agency has set up a permanent presence there. We have an office in Fukushima now, and experts and laboratory which is making its own, our own independent sampling and so far we have been able to confirm that the first releases of this water do not contain any radionuclides at the level that will be harmful."

Japan began releasing more than 500 Olympic swimming pools' worth of diluted wastewater from Fukushima into the Pacific on Thursday.
