MINSK, BELARUS - MARCH 13: Pasha (left) from the city of Baranovichi and Vova (right) Kazakhstan walk down the hallway of the Children's Oncology Center on March 13, 2006 in Minsk, Belarus. Both children have been diagnoised with lymphoma. On April 26, 1986, reactor number four at the Chernobyl Nuclear Power Station on the border of the Ukraine and Belarus exploded. The fire, which burned out of control for five days, spewed more than 50 tons of radioactive fallout across Belarus. The wind carried the heaviest radioactive deposits across Belarus, where even today a large portion of the land is considered uninhabitable. The government denied the accident happened for several days, allowing the people in the Gomel region of Belarus to linger in the radiation. The cause of the medical illnesses are often hard to find, and much harder to prove. But, the rise in the number of cancer cases and other health problems in this region is too great for any other conclusion ? it has to be the radiation. (Photo by Ezra Shaw/Getty Images)
