In this photo taken on Wednesday, March 19, 1996, five-year-old Alek Zhloba, who suffers from leukemia, is held by his doctor in the children’s cancer ward of the Gomel Regional Hospital, in Gomel, Belarus. There are tracks from medical procedures on his head. Much of the nuclear fallout from the 1986 Chernobyl disaster fell on Belarus. Thirty years ago, the Chernobyl Nuclear Power Plant exploded in Ukraine, spreading radioactive material across much of the Northern Hemisphere. (AP Photo/Efrem Lukatsky)
