On April 26, 1986, an explosion blew the roof off a nuclear reactor at Chernobyl in present-day Ukraine. It was to become the worst civilian nuclear disaster in history. Thirty years and 2,000 kilometers away, one group of people, and their animals, are still living with the consequences.
A visit to the Chernobyl exclusion zone might seem like an adventure to the tourists who flock there for a glimpse at disaster. Not so for the hundreds of thousands who were sent in to clean up the world's worst nuclear accident.
