Kovtun was not poisoned Nov 1

The half life of polonium 210 is thirty days in humans. Now, thirty five days after Litvinenko's Nov 1 poisoning, a Russian business man, Kovtun, falls seriously ill and into a coma* from Polonium 210 poisoning. Fishy? You bet. Why would someone fall drastically ill so rapidly so long after an initial exposure to Polonium? After all, Litvinenko was hospitalized only hours after he first fell ill. Do you think the timing of Kovtun's hospitalization could have anything to do with the British arrival in Moscow?

*Kovtun's layer says he is not in a coma. Why is there a discrepancy? Why would the hospital say otherwise?

The Russians will say "Oh, look, Litvinenko poisoned another man but poisoned himself in the process, case closed. Everyone go back to your business and forget about this incident."
