I haven't personally looked at any articles about this but I do know that this question has been studied extensively, if not exhaustively. The EPR paradox gives a good idea about the results. There does not seem to be any "machinery" backing QM that would give us a way to determine just which atom is going to decay next.If you think QM has an sensible explanation , I'm all ears ....

It's a little analogous to flipping a coin .... It could be wrongly said this is a random event . 50% will be heads 50% tails , any one flip will be 50/50 ... but that is only because we don't know all the causal factors , every time the thumb will flip with different force , sometimes the coin will spin 67 times , some times 91 times , too many unknowns we don't know ... but if we knew them we could predict when a head would come up and the illusion that flipping was a random event would disappear ...

A probing question is to ask what has caused a particular atom to just pop ...
