Very true, I didn’t think of this.
With a 1/2 life of 138 days, there would be nothing left after 8 years.
I think these Muslim “scientists” are the same ones who told the Ayatollahs that they were safe from any Israeli nuclear attack, LOL!

Depends on how much you started with. If you start with a billion Becqurel, after nine years you’d have 60 or so Bq left, that’s 60 disintegrations per second, which is measurable with a good counting system. It’s a few handfuls of atoms. The problem is the statistics, to distinguish that from the natural background.
