I agree (Sv is only for stochastic effects).
If we are at approx. 20 microgram of Po-210 this amount in itself can hardly

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
