We were just measuring air filters as we do on a weekly basis, 52 times a year, and suddenly there was an unexpected result.

Those levels do not exceed natural background radiation figures.""The composition of the nuclides may indicate damage to a fuel element in a nuclear power plant," the Dutch National Institute for Public Health and the Environment said.Lassina Zerbo, executive secretary of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), said its sensors also picked up the increased radioactivity levels, tweeting out a map showing the possible source locations  - but adding it was "outside the CTBTO's mandate to identify the exact origin".Watch: Video reveals what it's like inside Chernobyl.

Dan Satherley ... which as the Soviet Union experienced the world's worst nuclear accident in 1986 at Chernobyl (now part of Ukraine). 29/06/2020. That means the reprocessing activity was bound to be exothermic, or release heat, according to the study.On October 2, 2017, Italian scientists sent an alert to the Ring of Five about elevated levels of ruthenium-106, a radioactive isotope, in Milan. Russia’s worst post-Soviet naval disaster also occurred in the Barents Sea, when 118 crew died on the Kursk nuclear submarine that sank in after an explosion in August 2000. The SeverPost story appeared the next morning.

""We would like to get some more in-depth information on what actually happened," he said. The discovery marked the first time that ruthenium-106 had been found in the atmosphere since Chernobyl.Steinhauser said the explosion was the "single greatest release from nuclear-fuel reprocessing that has ever happened. It remains at levels that correspond to normal work of reactors. No incidents related to release of radionuclide outside containment structures have been reported.The marked part of the map covered parts of southern Sweden and Finland where there are nuclear reactors, but suspicion has fallen on Russia, which as the Soviet Union experienced the world's worst nuclear accident in 1986 at Chernobyl (now part of Ukraine).The good news is health authorities in Scandinavia say the radiation levels, though unusual, aren't at this stage harmful to human health.Though an exact source can't be pinpointed, their analysis points to western Russia.Russia has denied any of its power plants are behind a spike in radiation detected in the skies over northern Europe.Scandinavian health authorities detected 'radionuclides' across the peninsula and in the Arctic Circle last week. "It is likely that this exothermic trapping process proved to be a tipping point for an already turbulent mixture, leading to an abrupt and uncontrolled release. "We did not have any anticipation that there might be some radioactivity in the air. This provided "direct evidence that fuel reprocessing was the origin of the 2017 environmental release," the scientists wrote.

Aggregated emissions of all specified isotopes in the above-mentioned period did not exceed the reference numbers. "The spent fuel was unusually young with respect to typical reprocessing protocol," the scientists wrote.
