In November 2006, former KGB spy Alexander Litvinenko fell suddenly ill. He died in London's University College Hospital, leaving doctors puzzled over the cause of death. It was later determined he had ingested the radionuclide polonium-210. Given that (prior to the autopsy), radiation was undetectable out of Litvinenko's body, what was the type of radioactive decay?
