Here's an article that reports a claim that the Po-210 was planted.....
"Swiss scientists reported finding polonium levels of 54 millibecquerels
(mBq) and 180 millibecquerels on his belonging, considered to be high
"Because of the half-life of the substance, the conclusion is that the
polonium is much more fresh,"
....is Dr. Ely Karmon or an associate on Radsafe ?

I did the exercise. It's 21 half-lives. After that many
half-lives wouldn't a radionuclide be somewhat difficult to detect? By my
reckoning, that's 0.477 x 10 -6 parts remaining.
