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.
