LONDON: Three workers at London hotels visited by former Russian spy Alexander Litvinenko visited have tested positive for the radioactive isotope that killed him, British authorities said on Tuesday.
Seven workers at the Millennium Hotel's Pine Bar had already tested positive for polonium-210 but two more members of staff from the central London hotel have also been exposed, the Health Protection Agency said.
"Results received from a further two members of staff at the Millennium Hotel London Mayfair, and a member of staff at the Sheraton Hotel, Park Lane, London, show that they have been exposed to low levels of Po-210," the HPA said.
"These cases are related to areas which have been sealed off to the public as part of the police investigation. The levels are not significant enough to result in any illness in the short term and any increased risk in the long term is likely to be very small."
In Moscow on Tuesday, the Russian prosecutor general's office said it had completed a joint inquiry with visiting British detectives into the poisoning death of Litvinenko.
