What did tests on Arafat's body show? (2012)
On 6 November, al-Jazeera revealed the findings of 10 experts at the Vaudois University Hospital Centre (CHUV) in Lausanne. British forensic scientist David Barclay told al-Jazeera that at least 18 times the normal level of polonium-210 had been found in Arafat's rib.
"New toxicological and radio-toxicological investigations were performed, demonstrating unexpectedly high levels of polonium-210 and lead-210 activity in many of the analysed specimens" taken from Arafat's ribs, pelvis and soil that had absorbed his bodily fluids, the report said.
At a news conference to explain their findings, Francois Bochud said such high levels of polonium, "by definition... indicates third party involvement... Our results offer moderate backing for the theory of poisoning".
But he added a note of caution: "Was polonium the cause of the death for certain? The answer is no, we cannot show categorically that hypothesis that the poisoning caused was this or that."
