Russia on Monday said radioactive isotopes were released in a recent accident at an Arctic missile test site that caused widespread alarm as authorities kept details under wraps.
The August 8 blast killed five scientists and caused a spike in radiation levels but for several days Russia did not admit nuclear materials were involved.
The accident released swiftly decaying radioactive isotopes of strontium, barium and lanthanum, media reported, citing tests by the Rosgidromet national weather and environmental monitoring agency.
Alexander Uvarov, editor of the independent AtomInfo.ru news site, said the isotopes did not pose a threat to the population.
