There are two types:
Americium-241 is used in smoke detectors because it emits alpha particles that ionize the air inside the detector. This ionization process allows a small electric current to flow between two electrodes in the detector. When smoke enters the detector, it disrupts this current, triggering the alarm.
Americium is used in smoke detectors because it emits alpha particles that ionize the air, creating an electrical current. When smoke enters the detector, it disrupts this current, triggering the alarm. Americium has a long half-life, making it reliable for long-term use in smoke detectors.
The first smoke detector was invented in 1890 and used a simple design with a bent bellows chamber filled with air that would expand when smoke entered. This expansion would trigger a lever mechanism to sound an alarm. It was a basic system with limited effectiveness compared to modern smoke detectors.
Yes, smoke detectors are designed to detect all types of smoke particles, including cigarette smoke. When cigarette smoke particles enter the detector, it triggers the alarm just like any other type of smoke.
A beeping horn and red flash on a smoke detector usually indicate a low battery or a malfunction. It's important to replace the battery or the entire unit to ensure the detector functions properly in case of a fire.
no it was not
yes for the navy
Alpha radiation is emitted from the amercium button in a smoke detector. When smoke goes into the smoke detector it blocks the stream of alpha particles emitted from the americium. That triggers an alarm.
actually no, the smoke detector was not proposed for a mission
Personally, I have no idea what "smoke detector tape" is.

is a smoke detector like a sense organ

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.
Remove the batteries from the back of the detector.
Americium is used in smoke detectors because it emits alpha particles that ionize the air, creating an electrical current. When smoke enters the detector, it disrupts this current, triggering the alarm. Americium has a long half-life, making it reliable for long-term use in smoke detectors.
Americium-241 ionizes the air inside a smoke detector, making a small change in voltage when smoke is present.
