PARIS, December 4 (RIA Novosti) - A check conducted by Russia's nuclear watchdog revealed no violations of the nuclear materials storage and transportation rules, Konstantin Pulikovsky, the watchdog's head, said Monday.

Russian journalists asked Pulikovsky to comment on media reports that said polonium 210, used to poison ex-FSB officer Alexander Litvinenko in London, could have been produced in Russia.

"I say absolutely, definitely that no deviations from the norms on storage and transportation of nuclear materials, including polonium, were discovered," he said.

Russian defector Litvinenko, 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.
