The surging wildfires in Russia seem to be getting the upper hand right now during the hottest summer in the country's history.  The fires are spreading to the Bryansk region, where in 1986 a nuclear reactor exploded and sent radioactive clouds over a wide area.  Scientists are afraid that the dust that settled in the Chernobyl area could be redistributed by smoke from the fires to a larger region and pose a threat to the population.  Russian officials claim that they have this situation under control, but scientists disagree.  The situation is so bad that in Moscow about 700 people a day are dying from the heat and polluted air.
