> Po-210 emits a gamma ray, but at a very low branching ratio. I did a quick
> calculation and concluded that you would not be able to see a gamma field
> above background, even a very small distance away from a lethal dose of
> Po-210, or even a few tens of lethal doses of Po-210 (it doesn't seem like
> those guys were particularly stingy with the stuff).

> I was on a plane yesterday and noticed elevated gamma readings on my
> radiation detecting watch. (5 to 20 times normal BG before take-off and
> after landing and noticeably higher than what I am used to during flight.)
> Was told afterward that there were medical isotopes in cargo. But, you
> a lot of time to consider possible scenarios during a 4 hour flight.
> BTW, it's a pretty strange experience trying to tell an airline that their
> plane is radioactive. You don't know who to talk to and you are not sure
> they are going to stick you in a straight jacket. Especially, at a time
> all you hear on the news is about people getting killed with radiation and
> planes getting contaminated. The first few people you talk to do not know
> that there is radioactive material in cargo.
