Russia admits to being the source of radioactive pollution
By AFP the 20.11.2017
The Russian meteorological agency Rosguidromet acknowledged Monday that an "extremely high" concentration of ruthenium-106 had been detected in late September in several regions of Russia, confirming reports from several European radioactivity monitoring networks.
"The radioisotope Ru-106 was detected by the observation stations of Arguaïach and Novogorny" between September 25 and October 1, said Rosguidromet in a press release.
According to the same source, the highest rate was recorded in the station of Arguaiach, a village near Chelyabinsk, in the southern Urals, where "an extremely high concentration" of ruthenium-106 "exceeding 986 times "the concentrations recorded the previous month were detected.
Rosguidromet does not give any indication of the potential source of the pollution, but Arguaïach is located 30 kilometers from the Maïak nuclear complex, hit by one of the worst nuclear accidents in history in 1957.
Maïak is now a reprocessing site for spent nuclear fuel.
The Russian agency specifies that ruthenium-106 was then detected in Tatarstan and then in southern Russia, before it was fixed from September 29 "in all European countries, from Italy and to northern Europe ".
At the end of September, several European networks monitoring atmospheric radioactivity had detected ruthenium-106 in the atmosphere.
