Thank you for your comments.

I agree (Sv is only for stochastic effects).

If we are at approx. 20 microgram of Po-210 this amount in itself can hardly 
be seen by the eye - then as a dissolved preparation (ionic form) it can 
clearly not be seen.

Anyone who has worked with weighing chemicals knows that it becomes hard 
when you get down to a few milligrams (humidity, static electricity...). 
This in itself points at "professionals" being involved to provide some 
chemical carrier.
