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.

after a certain point, you're going to get to where you have to split an atom or two.

fairly sure that'd be far less exciting than normal.

Edit: i decided to try and figure out how long that would take.. and per usual the law of large numbers caused my eyes to glaze over.

half life times log2(amount of atoms), right?

I mean I didn’t get that far, I lost track of how many zeroes were in the half-life.

(It’s 704ish million, right?)
