IONIZATION SMOKE DETECTORS - FACTS
Smoke Detectors are a common household item. One type, ionization smoke detectors, use a small radioactive sources as a key component for detection of smoke particles. The radionuclide used in ionization smoke detectors is americium-241 (Am-241), which is bonded to a metallic foil and sealed within a small chamber. As long as you use the smoke detector as directed and do not open it, it poses no radiation health risk. Photo electric detectors us a light and sensor to detect smoke and do not contain radioactive material. Many smoke detectors may us both ionization and photoelectric features to achieve maximum detection.
WHAT TO LOOK FOR:
Unfortunately not all smoke detectors are marked the same. Different indicators may be used to determine if the smoke detector contains radioactive material or not. Observe the labels and markings on the original packaging or on the back of the smoke detector; and refer to the owners manual. If you see any of the following, the device does indeed contain radioactive material:
The radiation symbol in any size or color.
Any of these words:
Radioactive - Ionization - Americium - Microcurie - Becquerel or Nuclear Regulatory Commission
Any of these abbreviations:
Am-241 - p.Ci - kBq or NRC
If none of these markings occur, changes are the detector is photoelectric only and does not contain radioactive material.
