    How do I know if my smoke alarm is ionization or photoelectric?
    For both types of sensors in one alarm, install dual sensor smoke alarmsthat use both sensing technologies. To identify if you have an ionization, photoelectric or dual sensor smoke alarm, review the packaging or back of the alarm to find the smoke sensor symbol.

    Are ionization AND photoelectric smoke alarms better?
    Because both ionization and photoelectric smoke alarms are better at detecting distinctly different yet potentially fatal fires, and because homeowners cannot predict what type of fire might start in a home, CPSC staff recommends consumers install both ionization and photoelectric type smoke alarms in their home (www.cpsc.gov, July 2016)

    Are ionization smoke detectors safe?
    In contrast, ionization smoke detectors use a small amount of radioactive material (Americium-241) to facilitate their ionization process. While the radioactive materials in ionization detectors are generally safe in normal use, the absence of such materials in photoelectric detectors eliminates any associated concerns. 4.
