CAN SCIENTISTS PROVE WHETHER ARAFAT WAS POISONED WITH POLONIUM?

Scientists caution that traces on Arafat’s clothing aren’t sufficient proof of poisoning. Exhuming his body would a surer method. Derek Hill, a radiological science expert at University College London, said eight years after Arafat’s death in 2004, any polonium would have decayed and would be far less radioactive than it was at the time. But he says it would still be much higher than normal background levels and with an autopsy it should be possible to tell “with a pretty high confidence” whether Arafat had polonium in his body when he died.
