Norway’s nuclear safety authority is analyzing amounts of radioactive iodine detected in the air in northern Norway in the days after a deadly explosion during a rocket engine test over the border in Russia. Russia’s state nuclear agency, Rosatom, said on Saturday that five people killed in the blast were its staff members, and the accident involved “isotope power sources”, giving no further details.
Norway’s radiation and nuclear safety authority DSA said it had detected the radioactive iodine at its air filter station in Svanhovd, which is by the Russian border. A river separates the two countries. Russia’s state weather service said on Tuesday that radiation levels in the city of Severodvinsk had spiked by up to 16 times last Thursday, while medics who treated victims of the accident have been sent to Moscow for a medical examination.
