Web1 de mai. de 2024 · In a new paper in Fire Safety Journal (FSJ), a team of NASA and NIST researchers describe how they looked at the smoke particles produced by five materials commonly used aboard crewed … 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.
WebWhen smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm. The appropriate type of smoke detector must be installed to avoid them being disabled because dust or condensation sets them off falsely.
