Arafat didn't die from polonium 210, or it would have let lots of traces, and several victims. My guess, is any other radioactive substance, like thorium 232, left on his seat, on an international meeting.. Like Chavez

ok, review. all the instruments posted have radioactive substances 1. the amount are grams or micro grams 2. are sealed on lead disks 3. by using the instruments, the mercury on the refrigerator absorbs radiation, becoming high radioactive . 4. we can handle the sealed disk with no protection, until is taken out 5 not the mercury. 6 the mercury can only be stolen , with lenax gloves and lab mask 7 nothing else is needed if there's no leak
