Smoke Detectors

Smoke detectors or combination Smoke/Carbon Monoxide detectors may contain the radioactive material, Americium-241. When we reopen, bring all these detectors to our new Eco Depot Facility for recycling.


Is your smoke alarm is ionizing?
Look on the front, back, or inside of the unit for the words:
  • Photoelectric (P)-  photoelectric
  • Ion/Ionizer/Ionizing (i)- ionizing
  • Radioactive- ionizing
  • Americium- ionizing
to determine if your detector is photoelectric, ionizing or both.

Single purpose Carbon monoxide (CO) detectors do not use radioactive substances.
