Chernobyl: Humans more dangerous than radioactivity?

A nuclear accident devastated the region near Chernobyl, Ukraine, on April 26, 1986 leaving behind a 2,600 km² exclusion zone where some 350,000 people were evacuated. This vast area, where time has stood still ever since, is springing back to life with wildlife. The evacuation of the human population has created a unique wildlife refuge which has seen an increase in biodiversity.
