Evacuated in March 2011, the 20-kilometre exclusion zone around the Fukushima nuclear power plant has begun to give up its secrets. Vegetation in the area, where people are forbidden at risk of deadly radioactivity, has grown over cars left in traffic jams as a reminder of thousands of residents' panicked flight. An earthquake and consequent tsunami sent three cores at the Fukushima nuclear plant into meltdown in the largest nuclear accident since Chernobyl. Photographer Arkadiusz Podniesinski went into the zone.
