For proper disposal of a smoke alarm or detector, please check the label on the device or research the type of alarm/detector you have. Not all smoke alarms/detectors have radioactive materials. If it does not contain radioactive materials per the product description, you can remove the battery and dispose of the alarm/detector in the trash.
If your product does contain radioactive materials, the best and safest option is to first check with the product manufacturer to see if they offer a mail-back program. You may also check this website at www.curieservices.com for more recycling information, including a helpful Frequently Asked Question sheet. The Unites States Postal Services also offers additional resources here. Please note that some resources may require a fee for service.
If uncertain, you may contact our office at 714-834-4000 to speak to a materials regulation specialist.
