there was very little lead there, just alpha and X-ray radioactivity

I am not sure what are chemical properties of polonium, but plutonium
is considered very toxic chemically.

Actually, contrary to any urban legends you might have heard, nobody
really knows whether plutonium is chemically toxic since any chemical
effects it might have are completely swamped by its radioactivity.

What does the substance, that this guy ate, look like? I've
never seen radioactive stuff. Is it like a solid, liquid, gas?
Is it like a metal? Does it have a taste? If it is similar
to a marble, how can anybody be tricked into swallowing it?

I don't understand how shushi bar food could be used. It's all
raw.

A lethal dose of polonium is about 0.12 micrograms:
http://en.wikipedia.org/wiki/Polonium#Use_as_a_poison

It is far more toxic than ricin. which requires 0.2
http://en.wikipedia.org/wiki/Ricin

Such a small amount is practically invisible.
For comparison it would take about 50,000 micrograms (0.05 grams) of
strychnine to kill a 50 kg adult:

With all these alphas zapping things, how could the poisoner
keep it contained until ingestion. Would the poisoner be
contaminated too?

Alphas are very easily shielded against. A small lead container will
do nicely.

I've wondered about those poisons like ricin. Handling it, if
it absorbs easily must be a little tricky.

With this poisoning in the news, why would somebody pick
something so exotic? If Putin(sp?) did order it, a rare
metal isn't exactly the best way to bump the guy off.
There's thousands of other ways that can look like mere accidents.

That's the puzzling thing about the whole affair.
