World news report wildfires boosting radiation levels near Chernobyl, Ukraine. Ukrainian firefighters battled two wildfires on Sunday and Monday near the Chernobyl nuclear power station, which was evacuated during the Soviet era after a 1986 nuclear-reactor explosion. Radiation levels at blazes, which covered dozens of acres in the 1,000-square-mile Chernobyl Exclusion Zone, rose to 16 times above normal, said the head of the state ecologic outletsal inspection service, Yehor Firsov. The zone has been unpopulated, except for about 200 people who refuse to leave, since the disaster at the plant produced a cloud of radioactive fallout that drifted over Europe. Fires in the forests around the shuttered plant have been common. Radiation levels in the capital, Kyiv, remained within the normal range.
