Russia opens commission into nuclear incident report
The move comes despite Russia's denial that a nuclear accident had occurred at any of its nuclear facilities.
"Nuclear scientists have created a commission to discover the origin of ruthenium-106," Rosatom said in a statement, also released by the country's Nuclear Safety Institute.
The commission will include representatives of "Russian and European scientific organisations," according to the statement.
"Rosatom will offer all necessary assistance to this commission and will inform the public of the results."
On Monday, Russian meteorologists said a station close to the Mayak nuclear facility in the Chelyabinsk region detected "extremely high pollution" of the ruthenium-106 isotope during tests in late September.
The radioactive isotope is created by splitting atoms in a reactor and does not occur naturally.
Rosatom previously said there were "no incidents" at nuclear infrastructure facilities in Russia and that the concentration detected posed little threat. ■
