    Both kinds exist. Both have different benefits and drawbacks.

    You shouldn’t only be using one type in your house.

      No the ability of radiation based smoke alarms tends to cause false positives which in turn causes people to ignore them making them less effective. Optical smoke detectors are overall the newer and better technology.

      That being said radiation based smoke detection is still a cool concept. There might be a few areas where they perform better still, though probably not.

        For best protection, it is recommended both (ionization and photoelectric) technologies be used in homes. In addition to individual ionization and photoelectric alarms, combination alarms that include both technologies in a single device are available.

  Those detectors are inferior to optic detectors and should not be used any more.
