A nine month investigation into Yasser Arafat's unexplained death by Al Jazeera found a smoking atomic gun, Polonium-210. At least 80% of the Polonium, which is naturally found associated with uranium and it's decay products, was unassociated, indicating it came from neutron activation of Bismuth-209 in a nuclear reactor. If this was a poisoning, as it appears to be, only a very sophisticated group with access to nuclear facilities could have pulled it off.
Direct sampling of Yasser Arafat's body, if permitted, could show beyond a reasonable doubt that he was poisoned. Poisoning by unsupported Polonium could not happen naturally because it does not exist unsupported in nature.
Eight years after his death, it remains a mystery exactly what killed the longtime Palestinian leader. Tests conducted in Paris found no obvious traces of poison in Arafat’s system. Rumors abound about what might have killed him – cancer, cirrhosis of the liver, even allegations that he was infected with HIV.
A nine-month investigation by Al Jazeera has revealed that none of those rumors were true: Arafat was in good health until he suddenly fell ill on October 12, 2004.
More importantly, tests reveal that Arafat’s final personal belongings – his clothes, his toothbrush, even his iconic kaffiyeh – contained abnormal levels of polonium, a rare, highly radioactive element. Those personal effects, which were analyzed at the Institut de Radiophysique in Lausanne, Switzerland, were variously stained with Arafat’s blood, sweat, saliva and urine. The tests carried out on those samples suggested that there was a high level of polonium inside his body when he died.
