The article reports that no radiation has been detected in Norway following a test of Russia's nuclear-powered cruise missile, Burevestnik, which allegedly flew 14,000 km for about 15 hours. The test, confirmed by Russian military officials, raises concerns about its potential deployment and classification within Russia's nuclear arsenal, especially as the New START treaty with the U.S. is nearing expiration. Norway's radiation monitoring stations have reported normal levels, with officials stating that any potential radioactive release would take time to register.
