NEW: CVSWMD now accepts ionized smoke detectors for recycling at the ARCC! Fee is $5 per unit. ​




​​Smoke Detectors contain small amounts of a radioactive material; it poses little threat but can become a hazard if broken open.

  • How to tell if your smoke alarm is ionized?
  • ​
  • -Look on the front, back, or inside of the unit.- Check for the word “Photoelectric” (or the symbol “P”) or the word “Ionization” (or the symbol “i”)
- Note that any indication of the unit containing radiation indicates it is an ionization alarm.

Some smoke detectors contain a small amount of radioactive material called americium 241 (am-er-ish'-ee-um). Look on the back of the unit for the designation Am 241.  Some dual function alarms, for smoke and carbon monoxide detection, also contain americium. 

Single purpose Carbon monoxide (CO) detectors do not use radioactive substances; they can be recycled with E-waste.
