Sept. 25 (UPI) -- Crews have begun to clean up the site of a nuclear accident in Russia this summer that killed seven people and caused a brief release of radiation into the atmosphere.
Helicopters, soil excavators and crews in hazmat suits have been working at the site in Nenoska, in northwest Russia, since last weekend. U.S. satellite photos indicate the presence of a nuclear-powered cruise missile at the bottom of the White Sea at the time of the Aug. 8 explosion.
