# Did Russia Cover Up a Radiation Leak 100x Worse Than Fukushima?

![The massive radiation leak that plumed over Eastern Europe in 2017 was just definitively traced back to a Russian nuclear facility.](<https://futurism.com/wp-content/uploads/2019/07/russia-radiation-leak-fukushima.jpg>)

## Nuclear Detectives

A massive radiation leak, up to 100 times worse than the 2011 Fukushima power plant meltdown in Japan, plumed over Europe back in 2017. At the time, it was traced back to a Russian nuclear facility — but [Russia denied any involvement](<https://futurism.com/russia-finally-admitted-radiation-cloud-over-europe-real>).

Now, new research confirms that the original hunch was correct, [*New Scientist* reports](<https://www.newscientist.com/article/2211511-gigantic-mysterious-radiation-leak-traced-to-facility-in-russia/>). The study, [published this week](<https://www.pnas.org/content/early/2019/07/25/1907571116/tab-article-info>) in the journal *PNAS,* concludes that the massive cloud of radiation came from Russia — and that the government's alternative explanation that the leak came from a satellite burning up during re-entry was either a cover-up or grossly misinformed.

## Narrowing Down

In the new study, a team of European scientists traced the leak back to Russia's Mayak nuclear facility, located between the Ural Mountains and the Volga River, according to *New Scientist*. Russia denied that the Mayak facility was the source of the leak at the time, arguing that there weren't any traces of the radioactive ruthenium-106 isotope in the nearby soil.

But after studying reports from 1,300 radioactivity-monitoring stations throughout Europe and checking them against weather and air-flow patterns from the area, the team of researchers confirmed that the leak must have originated from the Southern Urals.

When the leak was first detected**,** [French scientists determined](<https://www.irsn.fr/EN/newsroom/News/Pages/20171109_Detection-of-Ruthenium-106-in-France-and-in-Europe-Results-of-IRSN-investigations.aspx>) that it wasn't dangerous to people in the area — which, again, was definitely within Russia.
