Many of the much older smoke detectors, and a small number of newer models, contain very small amounts of radioactive material. These ionization smoke detectors usually have a label on back or inside the battery compartment that says, “ionization”, mentions “americium-241 (Am-241)”, or “contains radioactive material”. When these types of smoke detectors are delivered to the H-MRF, they are properly disposed of through DEF’s hazardous household waste contractor. As for those smoke detectors that do not contain radioactive material – photoelectric smoke detectors, once the batteries are removed they can be disposed of in the trash.
