Russian Doctor Has Trace of Radiation After Explosion Associated Press MOSCOW - Over Russian 100 medical workers who helped treat victims of a recent mysterious explosion at a military testing range have undergone checks and one man has been found with a trace of radiation, officials said Friday. The Aug. 8 incident at the Russian navy's range in Nyonoksa on the White Sea killed two servicemen and five nuclear engineers and injured six. It was followed by a brief rise in radiation levels in nearby Severodvinsk, but authorities insisted it didn't pose any danger. The Arkhangelsk regional administration said Friday that 110 medical workers have undergone checks, and that one man was found with a low amount of radioactive cesium-137 in his muscle tissue. It said the man's health isn't in danger and argued that he could have got the radioactive isotope with food. The statement followed Russian media reports claiming that dozens of medical workers were exposed to radiation. .
