Radiation Cloud Over Europe, Not ‘Harmless’ to Those near Unknown Source, Nuclear Expert Says via EnviroNews

An airborne plume of radioactive ruthenium 106 from a nuclear accident was detected “in the atmosphere of the majority of European countries,” from late September through mid-October, according to France’s Radioprotection and Nuclear Safety Institute (IRSN) — but the source is still unknown. As of November 10, 2017, the manmade element has been identified in at least 28 countries.

While many news agencies are calling the cloud “harmless” and reporting the good news — that radiation levels are low and that no health consequences have been observed — radiation experts tell EnviroNews the scene may not be so peachy at ground zero where the release occurred. The question is: where exactly is ground zero?

In a report, the IRSN used wind and weather patterns, coupled with readouts from radiation monitoring stations throughout Europe, to deduce the “most plausible zone of release lies between the [Volga River] and the [Ural Mountains].” According to NPR, Jean-Christophe Gariel, Director for Health at the IRSN, said, the plume “has been traced to somewhere along the Russia-Kazakhstan border.”


The IRSN said the release likely came from a “nuclear fuel treatment site or centre for radioactive medicine,” according to Reuters.

The IRSN also wrote in its report, “there has been no impact on human health or the environment,” and many news agencies have since regurgitated this assertion in their reporting. But this is a difficult statement. The gestation period for the carcinogenic and mutagenic health consequences from even low-level radiation exposure is very long, and medical maladies may take decades to unfurl. The effects of exposure to ionizing radiation can also be multigenerational, deforming the genes of unborn children and grandchildren, predisposing them to medical conditions before they are born.

According to Gundersen, what the IRSN failed to mention in its report, is that while radiation levels over Europe may be “very low,” that may not be the case near the mystery facility where the accident occurred. “The ruthenium 106 concentrations at the detectors in Europe are [quite] low and these are very sensitive detectors,” Gundersen explained to EnviroNews. “That said, the concentration near the release point is likely quite high, and is not ‘harmless’ to those who are close by. That is why pinpointing the location of the release is so important,” Gundersen continued.


NPR concurred with Gundersen’s assessment, reporting, “modeling suggests that any people within a few kilometers of the release — wherever it occurred — would have needed to seek shelter to protect themselves from possible radiation exposure.” The IRSN also added that if a similar incident would have occurred within French borders, it would have required evacuation for an area with a radius of several kilometers.

As EnviroNews has reported in the past, air pollution concentrates most abundantly near its source. In the case of heavy metals and radioactive isotopes, larger particles with more mass, fall out faster and closer to the point of origin, whereas smaller particles can be carried on wind currents for hundreds or thousands or miles, falling to Earth wherever wind and precipitation carry them. The smaller and more vaporous the particle, the farther it can fly. Myriad finely disintegrated radioactive isotopes from both Chernobyl and Fukushima circled the globe for weeks following those accidents, and it has been stated by experts that to varying degrees, virtually every person on Earth has a piece of Fukushima and Chernobyl lodged inside them. Most human bodies also harbor the radioactive footprint from bomb testing — radiation that is still falling out and blowing around to this day.

Ruthenium 106 is a transuranic isotope created in nuclear reactors. The element is not present in nature. It has a half-life of 373 days, meaning it takes about 10 years for it to decay away after it is born as a byproduct of the nuclear fission process.
