A boy points to his grandmother's portrait in the Chernobyl victims' monument in Slavutich, some 30 miles away from the accident's site, and where many of the power station's personnel used to live, during a memorial ceremony on the night on Monday, April 25, 2011.

The world’s worst nuclear accident at Chernobyl took place 25 years ago when a blast at the power plant spewed a cloud of radioactive fallout over much of Europe and forced hundreds of thousands from their homes in Ukraine, Belarus and western Russia. Today, a 19-mile exclusion zone around the plant remains in place because of contamination from the plant. See more images from Chernobyl here.
