MOSCOW, December 6 (RIA Novosti) - British experts investigating Russian security service defector Alexander Litvinenko's death in London found insignificant traces of radiation in the U.K.'s Moscow Embassy, a diplomatic spokesman said Wednesday.
The spokesman told RIA Novosti that there is no threat to public health and the Embassy is working normally.
Litvinenko, 43, an outspoken critic of President Vladimir Putin's administration and a close associate of exiled oligarch Boris Berezovsky, died in a London hospital November 23. His body was found to contain a lethal dose of polonium-210, a radioactive isotope.
Traces of polonium-210 were also found in a dozen sites in London and on British Airways aircraft flying the London-Moscow route.
British police told TV channel Sky News Wednesday that they will investigate Litvinenko's case as a murder, given preliminary results of the forensic examination.
