Map highlighting Russia and Kazakhstan, with location of the Mayak nuclear facility

Russia says a nuclear accident has not occurred on its territory regardless of “extraordinarily excessive” traces of a radioactive isotope being discovered.

Russia’s climate service acknowledged it had measured air pollution of ruthenium-106 at 1,000 occasions regular ranges within the Ural mountains.

It mentioned there was no well being danger.

The announcement appeared to substantiate a report by France’s nuclear security institute which detected a cloud of radioactive air pollution over Europe.

The Institute for Radioprotection and Nuclear Security (IRSN) mentioned on 9 November it had detected ruthenium-106 in France. It added that the supply of contamination may have been an accident at a nuclear facility in both Russia or Kazakhstan.

Each nations mentioned nothing untoward had occurred at their vegetation.

The report by the Russian meteorological service, Roshydrome, is the primary official knowledge from the nation supporting the French report.

Roshydrome mentioned two stations within the southern Ural mountains discovered “extraordinarily excessive air pollution” of the radioactive isotope between September and October.

A station near the Mayak nuclear facility in Chelyabinsk area indicated ranges 986 occasions these of the earlier month, it mentioned, with out specifying the origins of the air pollution.

Mayak, owned by state nuclear firm Rosatom, is a big plant that reprocesses nuclear gas. It mentioned it was not the supply of the elevated degree of ruthenium-106 whereas Rosatom mentioned there have been no accidents at any of its services.

The Mayak plant was the scene of a significant nuclear accident in 1957, when a waste storage facility blew up.

Ruthenium-106 is a product of splitting atoms in a reactor and doesn’t happen naturally. It is usually utilized in some medical remedies.
