Radioactive soil, Fukushima Prefecture, Japan. Bags of soil, vegetation and waste contaminated by the Fukushima Daiichi nuclear disaster awaiting processing. The contaminated material will undergo high incineration and caesium removal to reduce radiation levels before being stored in a landfill site. The disaster, on 11th March 2011, was triggered after a magnitude 9.0 earthquake occurred 130 kilometres off the east coast of Japan causing a devastating tsunami. The tsunami damaged the Fukushima Daiichi nuclear power station, leading to the meltdown of three of the nuclear reactors and a leak of radioactive material. It was one of the world's largest nuclear incidents since the Chernobyl disaster of April 1986.
