How to Get Rid of Smoke Detectors

There are two types of smoke detectors: ionization and photo­electric detectors. 
Ionization smoke detectors contain a very minute amount of radioactive material known as Americium 241. Although the amount of radioactive materials in ionization detectors is so small that it does not pose a risk to human health, some municipalities do not allow them to be disposed of with municipal waste. 
Photoelectric-type smoke detectors do not contain any radioactive material, therefore they can be disposed of in the trash. 

If the detector contains radioactive material, it is required by law to have a warning label on the body of the detector. Look for a warning label or the international symbol for radiation on the back of the detector facing the mounting base.
