How safe is the release of Fukushima nuclear plant water?

Water used to cool nuclear reactors at the stricken Fukushima nuclear power plant in Japan is being released into the Pacific Ocean by Japanese authorities. The move has sparked protests and concerns about safety in the region and met with retaliation from near neighbour China. But how safe is the water that’s been released? Presenter Charlotte McDonald and reporter Calum Grewar investigate, with the help of Professor Jim Smith of the University of Portsmouth and Professor Gerry Thomas, formerly of Imperial College London and the Chernobyl Tissue Bank.Presenter: Charlotte McDonald
