But carpedebass.. what would this in turn mean for the presence of any Polonium-210 left in the resulting liquid?
It is likely not there. If it is, it is likely in such minute concentrations, it would probably do you no harm. People see the term "radiation" and panic. Radiation (including Po-210) in one form or another is all around us, and cannot be avoided. The saving grace is that it is in concentrations that the body can handle. It's all a matter of concentration. Too much, of course is bad. But Po-210 is all around you. It occurs naturally at safe levels.
That said, in terms of radioactivity, it is highly radioactive but the alpha particles are not easily absorbed. Typical decontamination practices to the best of my knowledge include simple hand washing or showering.
The half life is also relatively short. If I recall correctly, about 130 days. Given the fairly high volatility of it, and the low absorption rates, I would seriously be surprised if enough remained post extraction to do you any harm.
In terms of tobacco, there have been elevated levels found on tobacco leaves (and other broad leaf plants) but, again, simple washing takes care of most of it. I'm not convinced there is even too much REAL truth to the article listed by the OP regarding analogs. This could be simple media hype. With the small absorption rate and fair volatility...I'm not completely convinced that this is a real hazard. Again, however, I am NO EXPERT in radioactive materials.
*EDIT* I am MUCH more concerned about the other contents of analog smoke.
