I saw a specific quote that made me question this : "Other atoms in the universe don't influence the rate, it's just an intrinsic property of each separate atom that it has some chance to decay." (from this Q&A)
I'm assuming there are some factors that do influence rate of decay? Also assuming that statement is generally correct in a broad sense, or even technically correct because it only mentions other atoms not influencing the rate - I've no idea, why I'm asking.
But there has to be some factors that influence rate of decay, even if only at a quantum level, right?
I've read here amongst other answers. I understand this may not be answerable, or the answer is simply "best evidence says its random" - but that question is 3 years old, and I'm hoping maybe the consensus has changed/shifted/new concepts are being explored.
I'm also curious about environmental factors. i.e. could uranium 233 decay differently (more rapidly/slowly), on average, in different settings? What causes the differences (pressure, presence of other atoms, ?) - this part I've yet to find any answer on, the others, I assume, imply a standard environment to show randomness of decay.
To go further, and my apologies if my ignorance is showing, does the presence of one versus many atoms change the rate of decay (again, avg)
To restate the question (title): What factors affect the rate of decay of an atom?
Please comment with any improvements
