Nuclear cloud no concern
EUROPE’S radiation experts are on alert over a cloud of radiation that has been drifting across the continent.
While its radiation level is harmless, scientists don’t know where it came from, although it has been tracked from Russia or Kazakhstan.
“The concentration levels of Ruthenium-106 in the air that have been recorded in Europe and especially in France are of no consequence for human health and for the environment,” France’s Institute for Radiological Protection and Nuclear Safety said.
“The release, accidental with regard to the quantity released, would have occurred during the last week of September 2017.”
Ruthenium-106 is a by-product of a nuclear reaction and doesn’t occur naturally.
But analysts don’t believe it came from a nuclear power plant, being more likely from a nuclear fuel preparation or nuclear medicine site.
The radiation was measured at 100 to 300 terabecquerels (the number of nucleus decays per second).
The 2011 Fukishima disaster emitted about 900,000 TBq, and the 1986 Chernobyl catastrophe 5.2 million TBq.
