Explain why americium-241 would be an ideal isotope to use in a smoke detector?
Alpha particles from americium ionized the air. An air with smoke has a different ionization, ionization currents which are also different are measured, compared and the detector (which is before calibrated) is ready !
Can you buy smoke detector tape?
Personally, I have no idea what "smoke detector tape" is.
Was the smoke detector proposed for a mission?
actually no, the smoke detector was not proposed for a mission
Is a smoke a detector like a sense organ?
is a smoke detector like a sense organ
Is a smoke detector like a sense organ?
is a smoke detector like a sense organ
Can a smoke detector sound from heat only?
Then it wouldn't be a smoke detector, but there are fire alarms that are triggered by temperature.
Do I need a battery smoke detector as a backup?
If your home smoke detector is tied into your electricity and is equipped with a battery backup you should not need an additional smoke detector. You should insure that the batteries are charged and that the smoke detector is functioning properly at least once a month if not more often.
How do you unplug a smoke detector?
Remove the batteries from the back of the detector.
How many type of smoke detectors?
There are basically two types of smoke detector; one type measures the opacity of the air to literally "see" if there is smoke. The other type tests for ionization that occurs when there is a fire. That type smoke detector uses a small radioactive chip to determine if freshly ionized smoke is present. It's a far more accurate means of determining the presence of fire and associated hazardous smoke. Many smoke detectors use a combination of both detectors. A separate type of detector is the carbon monoxide detector, which senses the presence of harmful carbon monoxide in the air. Most will even indicate the percentage of carbon monoxide. Note that carbon monoxide is typically present when a furnace or other heating device malfunctions.
How does a radioactive smoke detector?
Americium-241 ionizes the air inside a smoke detector, making a small change in voltage when smoke is present.
How you build a fire detecter?
Actually they are smoke detectors, they detect the result of the fire, smoke. A smoke detector works as follows: There is a chamber with a small nuclear source in it. Smoke particles are hit by the radiation and are ionized, ie, an electron is knocked off the particle leaving the particle with a charge on it. The chamber has two parallel plates in it with a voltage across the plates. The ionized particles are attracted to one of the plates, causing an electric current to flow. This current is amplified and detected and sets off the alarm.
Why does your smoke detector beep only at night?
Incase you are sleep and a fire starts the smoke detector will wake you up
