How should I dispose of a smoke detector?
Answer: There are two types of smoke detectors used in homes: Photoelectric and Ionization. Photoelectric detectors do not contain radioactive material and can be disposed of in your regular household trash. Ionization Detectors (most detectors in use are this type) do contain a small amount of radioactive material. Even though the amount is so small that it does not pose a risk to human health is it not recommended that they be disposed of with household waste. Ionized smoke detectors should be returned to the manufacturer for disposal. Please contact the manufacturer to determine what type of detector you have and what their return procedure is.
