A Russian nuclear reprocessing plant is the likely source of the mysterious cloud of radioactive ruthenium-106 that spread across Europe in 2017, experts said.
At its most intense, the cloud’s radiation levels reached 176 millibecquerels per cubic meter of air — 100 times higher than noted in Europe after the Fukushima meltdown.
The exact source of the cloud had been uncertain — although the highest radiation levels were detected in Russia, the Federation has denied responsibility for the leak.
In order to pin down the origins of the incident, radiation expert Georg Steinhauser of the University of Hanover, Germany and colleagues analysed more than 1,300 measurements of the cloud taken from across Europe and beyond.
These recordings were taken across 176 measuring stations in 29 different countries, reflecting the vast geographic spread of the cloud, which not only covered large parts of Europe but reached as far as the Arabian Peninsula, Asia and the Caribbean.
‘We measured radioactive ruthenium-106,’ said Professor Steinhauser.
‘The measurements indicate the largest singular release of radioactivity from a civilian reprocessing plant.’
