Fukushima nuclear plant: Is flushing out wastewater safe?

Japan is due to start releasing treated radioactive water from Fukushima nuclear plant into the Pacific Ocean, despite opposition from neighbouring countries. <br /><br />A 9 magnitude earthquake hit Japan's east coast in 2011, killing 18,000 people and displacing a further 150,000 from an exclusion zone around the plant. <br /><br />Some 1.34 million tonnes of water - enough to fill 500 Olympic-size pools - have been stored in tanks since a tsunami destroyed the plant, but space is now running out. The water will be released over a 30-year period after being filtered and diluted. <br /><br />On the Sky News Daily with Niall Paterson, our Asia correspondent Helen-Ann Smith describes the mood in neighbouring countries opposing the water release. <br /><br />Plus, Jim Smith, professor of environmental science at the University of Portsmouth dispels concerns about the levels of radiation, insisting there is no need to worry. <br /><br />Producer: Soila Apparicio <br />Interviews Producer: Alex Edden <br />Editor: Philly Beaumont
