The results were staggering. Yablokov’s team estimated that just in the first 20 years after the Chernobyl meltdown, some 986,000 deaths attributable to it occurred, many in parts of Ukraine, Belarus and Russia. The percent of children living in these areas considered in good health plunged from 80% to 20%. Rates of certain cancers soared, including childhood thyroid cancer in Ukraine (20 times higher) and Belarus (200 times higher). Rates of disease in covering many organs in the body all increased in areas closest to Chernobyl.
