It's usually americium-241. It undergoes alpha-decay with a half-life of about 400 years. Am-241 is artificially manufactured; it doesn't occur in nature.

What was used in fire detectors before americium?
The first smoke detectors are based on optical principles - photoelectric detectors.
What does alpha alpha radiation do?
It can be used for smoke detectors
What does americium do in smoke detectors?
Yes, americium is used as ionizing source in smoke detectors.
What is the element used for storing and transporting radioactive material?
The correct answer is LEAD. You can find the same question/answer if you type in "The element used for storing and transporting radioactive materials is?" in the search bar.
Do smoke detectors have to be on a desginated circuit in bedrooms?
Putting smoke detectors on a designated circuit is a good design policy. One of the features of a designated design is that the smoke detectors can be all looped together. The smoke detectors of today have a third terminal where if one detector trips all of the detectors on the circuit have the ability, if connected, to alarm. All of the detectors are wired with a 3 conductor #14 cable. The black and white wires are used for power to the detector and the third red wire is used on the third terminal to alarm all of the detectors on the circuit when one smoke detector trips. With all detectors in an alarm mode it is hard not to hear or sleep through any emergency because of closed doors blocking the sound. Using this method of connection it is recommended a detector in each bedroom and above the stairwell between floors. Keep away from the kitchen area or the whole house will know when someone burns the toast.
What synthetic element that is used in smoke detectors?
Americium (isotope 241) is the most common radioactive element used in smoke detectors.
What is a radioactive element used is smoke detectors?
Americium 241
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.
A synthetic element used in smoke detectors?
Americium (pronounced /ˌæməˈrɪsiəm/) is a synthetic element that has the symbol Am, the atomic number 95, and is used in smoke detectors.
Why are radioactive elements commercially important?
A radioactive element is an element that emits radiation due to instability. They are commercially used in the generation of electricity in nuclear power plants and home smoke detectors among other things.
Was uranium ever used in smoke detectors?
no. The most commonly used radioactive material is Americium
What element is used in smoke detectors and named for the US?
AMERICIUM 241!
Where is Americium commonly used?
Americium-241 is a radioactive isotope commonly found in smoke detectors.
What is the element americium used in?
One use is in smoke detectors to warn of fire.
When hydrogen reacts with the active metals it?
A synthetic element that is used in smoke detectors is
Is technetium a synthetic element used in smoke detectors?
Americium is the radioactive element used in ionization type smoke detectors. It is a by-product of the nuclear power industry. In the device, it is present as the oxide, which is rather chemically inert and has a high melting point. As a small capsule enclosed in metal foil. Your exposure to radiation from an ionization smoke detector is smaller than your exposure received by sleeping alongside your partner who is converting K40 into Ar40.
Which actinide is used in some smoke detectors?
Americium (element 95 on the periodic table)
