Six sites show radiation traces

Britain has launched an inquest into the former Soviet spy's poisoning death.
LONDON (AP) -- The British government began tracking radioactive hot spots in London on Monday to trace the poison that killed a former KGB agent, and three people who reported possible symptoms of contamination underwent testing.
Britain announced a formal inquest into the death of Alexander Litvinenko, but Home Secretary John Reid warned against rushing to conclusions over who might be responsible for the killing of the ex-spy turned Kremlin critic.
Litvinenko died Thursday after falling ill from what doctors said was poisoning by polonium-210, a radioactive isotope usually manufactured in specialized nuclear facilities. High doses of polonium, which is deadly if ingested or inhaled, were found in Litvinenko's body.
"The nature of this radiation is such that it does not travel over long distances, a few centimeters at most, and therefore there is no need for public alarm," Reid said in a special address to the House of Commons.
Police were able to interview Litvinenko in the hospital before he died, and are retracing Litvinenko's steps on the day he said he fell ill.
Sites of radiation
Six sites showed traces of radiation linked to the poisoning, including a bar in London's Millennium Hotel, a branch of Itsu Sushi near Piccadilly Circus, Litvinenko's house in North London and a section of the hospital where he was treated when he fell ill Nov. 1.
Two other sites -- an office block in London's west end and an address in the posh neighborhood of Mayfair -- also showed traces of radiation, Scotland Yard said.
All the locations except Litvinenko's home are in west London, separated by about a mile.
The building near the Millennium Hotel contains a business intelligence company, Titon International Ltd. -- whose CEO was a former U.K. Special Services director, and Erinys UK Ltd., an international security and risk management company.
The other location reportedly houses an office of Boris Berezovsky, the self-exiled tycoon and Kremlin critic wanted in Russia on money-laundering charges.
The sushi restaurant and part of the hospital have been closed for decontamination.
