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.
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.
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.
