Ionization smoke detectors contain small amounts of radioactive materials. Never disassemble a smoke detector. Intact detectors pose little threat, but can be a health hazard if broken open. By federal regulation, all smoke detectors contain the mail-back address to send used units with radioactive chips. The address of the supplier may be listed in the product warranty or user's manual. The U.S. Nuclear Regulatory Commission suggests checking the label on the detector for disposal options, but residents may safely discard individual units in their regular garbage.
