Russia said on Monday it had detected no sign of a radiation emergency, after an international body reported last week that sensors in Stockholm had picked up unusually high levels of radioactive isotopes produced by nuclear fission.
The Comprehensive Nuclear Test Ban Treaty Organization (CTBTO), which monitors the world for evidence of nuclear weapons tests, said last week one of its stations scanning the air for radioactive particles had found unusual, although harmless, levels of cesium-134, cesium-137 and ruthenium-103.
The isotopes were "certainly nuclear fission products, most likely from a civil source", it said. It tweeted a map showing where the material was likely to have originated, which included parts of several Baltic and Scandinavian countries as well as a swathe of western Russia.
