Mysterious Spike In Radioactivity Over Northern Europe, Accident At Russian Nuclear Plant Suspected

An anonymous reader quotes the International Business Times:
Watchdog agencies last week detected an increase in radioactivity levels in the atmosphere over northern Europe, suggesting a potential damage at a nuclear plant. Authorities noted the possibility that the spike may be the result of accidental release of radioactive material from one of the nuclear plants in Russia, but a spokesman denied any problems with the Russian power plants. Several Scandinavian watchdog agencies detected elevated levels of radionuclides cesium-134, cesium -137 and ruthenium-103 over parts of Finland, southern Scandinavia and the Arctic. Although the levels are not considered harmful to human health and the environment, radionuclides are artificial, unstable byproducts of nuclear fission, suggesting that the sudden increase in levels may have resulted from a damage in a nuclear power plant. According to the Associated Press, the Swedish Radiation Safety Authority noted Tuesday (June 24) that locating the origin of the radionuclides is “not possible” but by Friday, the National Institute for Public Health and the Environment in the Netherlands announced that calculations revealed that the radionuclides may actually have come from the direction of Western Russia… In 1986, it was a similar detection in Sweden that contributed to the reveal that a disaster had occurred in Chernobyl.
