Moscow says ‘extremely high’ levels of ruthenium-106 discovered as Greenpeace urges inquiry into possible cover-up
Russia’s meteorological service has confirmed “extremely high” concentrations of the radioactive isotope ruthenium-106 were found in several parts of the country in late September, confirming European reports about the contamination this month.
“Probes of radioactive aerosols from monitoring stations Argayash and Novogorny were found to contain radioisotope Ru-106” between September 25 and October 1,” the Rosgidromet service said.
The highest concentration was registered in Argayash, a village in the Chelyabinsk region in the southern Urals, which had “extremely high pollution” of Ru-106, exceeding natural background pollution by 986 times, the service said.
