Platelets

Arafat has a platelet problem. They say it is not due to leukemia. Information seems unnecessarily restricted. Thrombocytopenia is not rare but unusual. Why the secrecy? Could he have naively obtained a radioactive device and be suffering the toxic effects of careless handling? Once one asks oneself the question it even seems a likelihood. I wonder if small bombs can be traced from a satellite by their radioactive signature.
