Stay prepared with the most reliable smoke detectors for fire and carbon monoxide detection -- tested and recommended by our ...

They work differently in order to detect smoke. Ionization detectors use a very small amount of radioactive material inside of an ionization chamber with electrically charged plates. When smoke ...

it’s everything you need to build an Internet-connected smoke alarm. Smoke alarms, or at least ionization-based alarms with a tiny amount of radioactive americium, are very simple devices.

It’s widely known that a smoke detector is a good ionizing radiation source, as they contain a small amount of americium-241, a side product of nuclear reactors. But what about other sources?

The best smoke detector can provide an important first line of defense from fire. We recently put the top smoke detectors to the test. See which ones performed best.

Typical consumer products available to the general public that contain small amounts of radioactive material include for example ionization chamber smoke detectors for use in private homes. These ...

All smoke detectors use one of two types of sensors to detect fires. Ionization-type sensors are best at detecting fast-burning fires, while photoelectric sensors are generally better at alerting ...
