There is no reason to think the poisoner would be dead unless he ate the stuff or sucked it off his fingers. Unlikely. The poisoner could have washed his hands in Polonium and been quite safe unless he ingested it.
The BA stuff to staff says that the holds are not affected and it is the cabin that is the subject of these tests, so baggage handlers need not worry. I'm sure none of the rest of us need worry either.
Oh, and your smoke detectors contain an Alpha source too. There is an emitter and a detector. If smoke gets inbetween the two, it stops the Alpha getting to the detector and sets it off. I wouldn't be surprised it it were Polonium in them, but it could be many things.
