Smoke detector false alarm: Why is your fire alarm going off …
WebIonization smoke detectors use an ionization chamber and a source of ionizing radiation to detect smoke. This type of smoke detector is more common because it is inexpensive and better at detecting the smaller amounts of smoke produced by flaming fires. Inside an ionization detector is a small amount (perhaps 1/5000th of a gram) of americium-241. Web23 feb. 2024 · Ionization smoke alarms contain an insignificant amount of radioactive material between two electrically charged plates. This material ionizes the air (hence the name), which causes a current to flow. If smoke enters that area, it disrupts the flow of ions, which activates the alarm. diablo pc game free
