The lump would still have about 14% uranium still in it. (If my understanding of half-life is correct)

Afaik its always going to have some parts of uranium right? 50% after one half life, 25% after two half lives and it will keep on halving practically forever (or till the last atom decays). In the end it comes down to when you consider it a negligible amount.

I mean, yes, that's how it would work if there were an infinite number of atoms in the piece. There's a finite amount, though, so eventually there will be a point when all the atoms have completely decayed.

All models are wrong, but some are useful.
