How can I dispose of my old smoke detectors?

The two types of smoke detectors are ionization and photoelectric detectors. Ionization smoke detectors contain a very minute amount of radioactive material known as Americium 241. Photoelectric-type smoke detectors do not contain any radioactive material. The amount of radioactive material contained in ionization smoke detectors is so small it does not pose a risk to human health. If the detector contains radioactive material, it is required by law to have a warning label on the body of the detector. Look for the label on the back of the detector facing the mounting base. For this reason, smoke detectors containing radioactive material should be returned to the manufacturer for disposal.

When returning a detector to the manufacturer, include a note indicating the detector is to be disposed of, and mail it to the address listed on the back of the detector. The following smoke detector manufacturers/distributors will take back their smoke detectors:
