How do smoke detectors detect smoke?
Smoke detectors detect smoke by not detecting it. They sense not the smoke, but the oxygen levels surrounding it. when the oxygen levels drop, or when smoke replaces the oxygen, the alarm goes off.
Why is curium 242 not suitable for use in smoke detectors?
It is radioactive. ------------------------------- Incorrect answer: americium-241, the usual isotope in smoke detectors is more radioactive.
Why do smoke detectors beep at night?
You might need to put new batteries in
How is radioactivity used in smoke detectors?
There are two types of smoke detectors:Photoelectric Smoke detectorsIonizing Smoke DetectorsIonization smoke detectors are more commonly used. The smoke detector uses an ionization chamber and a source of ionizing radiation to detect smoke.Alpha particles are emitted from from the chamber, which ionize the air, so that the air conducts electricity and a small current flows.If smoke enters the alarm, it absorbs the alpha particles causing the current to reduce, and the alarm sounds.Generally, smoke detectors use a weak source made of Americium-241 (241Am95).Note: Alpha particles are the nuclei of a Helium Atom (4He2).
What year were smoke detectors invented?

Can smoke detectors detect smoke in the ciling?
No
Are smoke detectors and smoke alarms the same?
no
Are interlinked smoke detectors a good idea?
There are several types of smoke detectors that can be used in the home. Interlinked smoke detectors can interlink smoke and heat detectors for better convenience. Also, wireless units can be configured specifically to your needs. More safety and smoke detector information can be found on: http://www.safelincs.co.uk/Smoke-Alarms/
