A nine-month investigation by Al Jazeera discovered rare, radioactive polonium on the ex-Palestinian leader's final belongings. The finding suggests that Arafat was poisoned with polonium, a rare, highly radioactive element. The polonium was found in blood, sweat, urine and saliva stains on his personal effects, and the levels recorded by forensic pathologists in Switzerland - who studied the items - do not occur naturally. Al Jazeera's Clayton Swisher reports.

A nine-month investigation by Al Jazeera has revealed that Yasser Arafat was in good health until he suddenly fell ill on October 12, 2004.
Further tests revealed 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.
So what does Polonium do to a person?
It is actually harmless when it's outside the body, but inside, it becomes one of the deadliest substances known.
An amount equivalent to the size of a particle of dust is lethal.
After being taken into the body, Polonium quickly gets into the blood stream. Then it bombards people's cells with millions of radioactive alpha particles.
It damages the organs - first the liver and the kidneys, causing jaundice. It damages the intestines, cuasing toxic shock syndrome. And finally, it attacks the heart.

Al Jazeera continues its investigation into Yasser Arafat's death.
Research revealed that Arafat may have been killed by ingesting one microgram of radioactive polonium-210, around eight years ago.
Palestinian negotiator Saeb Erekat, who was Arafat's chief negotiator, calls for an international investigation committee to further investigate the matter.

The final report from the Institute of Radiophysics in Lausanne, Switzerland, found abnormal levels of radioactive polonium on Arafat's belongings.
Polonium is a rare and highly radioactive element. It is found naturally in the atmosphere and in the earth's crust, though in miniscule quantities.
Live from Canberra is George Dracoulis, professor of Nuclear Physics at the Australian National University, who explains in greater detail what polonium 210 is, where it comes from, how it is produced and how it can potentially kill a human being.

A nine-month investigation by Al Jazeera has discovered rare, radioactive polonium on ex-Palestinian leader's final belongings.
Most of it was "unsupported" polonium, an artificial type produced in nuclear reactors, according to forensic pathologists who studied his belongings. Polonium is the same chemical used to kill Russian dissident Alexander Litvinenko in 2006.
