Can we infer from this that Mr Litvinenko smoked himself to death?

I know this isn't serious but:

I think the key word in that link is trace

A cigarette will give you about a millionth of a Sievert

The average background radiation you or I get walking around the country is about 2 milliSieverts or a couple of thousand times that.

The LD50 is the 50% lethal dose. It is the amount of a substance in which 50% of the population would die in 60 days.

In terms of radiation it is about 4 Sieverts


Alexander Litvinenko had a dose of several tens of Sieverts apparently.

He'd have had to have smoked 10s of millions of cigarettes
