Yesterday while cooking I set off the smoke detector, no I did not burn anything. They go off when I cook over a high heat. And yesterday once they started going off they would not stop. I ended up having to disconnect them all (they are hard wired with an interconnect) and I replaced them this morning. Aaaaaaaand let me tell you, I had a sleepless night last night knowing there were no detectors installed.

This is plain WRONG and DANGEROUS.
The issue is NOT the Americum but the natural degration of the photoelectric cells and the accumulation of dirt within the test chamber.
Even before that time the risk for false alarms is increased substantially by degration before the chances for sucessful alarming decrease rapidly. Due to that they actually withstand aging actually worse than ionisation based devices.
Sientific sources?

(Besides: Americum has a decay time of over 400 years,btw)
Your third source is about the 2020 follow-up study of the 2017 study in your first source. You’ve “only” got three independent sources even though it looks like four (“only” in scare quotes because three is still plenty).
A follow up is a absolutely regular thing and does not diminish neither study.
I didn’t say they were diminished. I said they weren’t independent.
