An example of deterministic effects
The Litvinenko affair: Alexander Litvinenko was a former KGB officer who was poisoned with polonium 210 in 2006. The very high doses he ingested had clear, reproducible and deadly effects. Litvinenko died on the 23rd of November 2006, about three weeks after having swallowed a poisoned cup of tea while staying at a London hotel. The former KGB agent absorbed several times the lethal dose of polonium, a radioelement some 12 billion times more radioactive than uranium.
