What is the smoke detector label?
Radioactive
What device fitted into homes has a radioactive element?
The smoke detector.
Many smoke detectors contain?
a. Americium-241 Smoke detectors might have an ionizing chamber. If it does, the chamber holds a radioactive nuclide to ionize the particles in the smoke to set off the detector. Usually the radioactive source is americium.
Can the radiation in a smoke detector escape?
No, the radioactive sources in smoke detectors emit alpha particles. These are very weakly penetrating and are stopped by a few centimetres of air, therefore the plastic casing of the detector is sufficient to stop any radiation.
A synthetic element that is used in smoke detectors is?
Americium-241 this is an emitter of alpha radiation, which is used in smoke detectors as it is very ionising and will not be able to travel through smoke. Therefore, in a fire the detector will not receive any alpha radiation and hence the alarm will go off.
Was the smoke detector proposed for a mission?
actually no, the smoke detector was not proposed for a mission
Can you buy smoke detector tape?
Personally, I have no idea what "smoke detector tape" is.
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.
How do you unplug a smoke detector?
Remove the batteries from the back of the detector.
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.
