Smoke detectors contain highly toxic Americum 241 isotope. It's not that hard to remove it from the ionization chamber.

- Reason077 9y agoMost modern domestic smoke detectors are now photoelectric, rather than ionization based. Not only do they not contain toxic Americum 241, photoelectric smoke detectors are also both more sensitive to real fires and less prone to false alarms. (The later is actually really important, as people will often disable smoke detectors in response to a false alarm - and then forget about them)
