ok, there's 50% chance the Mi6 lied, and 50% chances they didn't. about Litvinencko . Because there's a lot of myths about polonium 210, and ignorance doesn't lead us anywhere! Polonium 210 high grade from a nuclear reactor, with skin contact or breathing it kills you,and everybody around. On tobacco, it kills you with leukemia, because actually, if placed on high temperatures like on a cigarette smoke, it looses 75% of its radioactive. Therefore polonium 210 only lives in low temperatures. But, if in a drink, it dissolves and actuates, when a powder, but you just can not handle it safe. !!!!! So, how the hell did the americans wanted to change Fidel cigars ??? What was the modus operandis from the KGB, to handle the po 210? and yes, Arafat died of leukemia....anti radiation vaccines?
