(once again, just like chernobyl...) Russia denies nuclear accident after radioactive traces found
Russia says a nuclear accident has not occurred on its territory despite "extremely high" traces of a radioactive isotope being found.
Russia's weather service acknowledged it had measured pollution of ruthenium-106 at 1,000 times normal levels in the Ural mountains.
It said there was no health risk.
The announcement appeared to confirm a report by France's nuclear safety institute which detected a cloud of radioactive pollution over Europe.
