The production of polonium starts from bombardment of bismuth ( 209Bi) with neutrons at the Mayak nuclear reactors in Ozersk, near the city of Chelyabinsk in Russia. The product is then transferred to the Avangard Electromechanical Plant in the closed city of Sarov. [28] [104] [105] [106] This of course does not exclude the possibility that the polonium that killed Litvinenko was imported by a licensed commercial distributor, but no one—including the Russian government—has proposed that this is likely, particularly in regard to the radiation detected on the British Airways passenger jets travelling between Moscow and London.
