British police say there’s no sign of radiation in the home of exiled Russian oligarch Boris Berezovsky, who died under mysterious circumstances.  Berezovsky was a political enemy of Russian president Vladimir Putin.

He was also a friend of Alexander Litvinenko, the former Russian spy who was poisoned with radioactive material in London in 2006.  Before he died, Litvinenko publicly blamed Putin for his death.  Both men accused Putin’s government of crimes and corruption.

67-year-old Berezovsky survived previous assassination attempts, including a bombing that killed his chauffeur. 

But he was having a hard go of it in exile.  He made millions in the economic free-for-all of post-Communist Russia, importing luxury cars for the rising class of oligarchs.  But after fleeing Putin's rise and heading to London, he found it more difficult maintaining that wealth in a country that actually had rules.  He lost $6 Billion in a lawsuit over shares in Russia's fourth biggest oil company.  It was rumored he was about to lose his vast mansion in Berkshire outside London.

Berezovsky recently gave an interview in which he seemed to be struggling to find a reason to live.
