Americium-241 is a radioactive isotope and used in smoke detectors to ionize the air (gives air molecules a charge). This allows a small current t flow between two contacts placed in the air chamber. When smoke particles enter the chamber, they attach themselves to the ionized molecules (by electrostatic attraction) effectively making them bigger and slowing the current. The detector then goes off when the current slows.
Americium become to be largely used in smoke detectors after 1970.
Americium (isotope 241) is the most common radioactive 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.

Smoke detectors are devices that detect smoke. They are used as warning devices in houses to warn people of fire.

americinium is used in smoke detectors to check for smoke
The first smoke detectors are based on optical principles - photoelectric detectors.
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/
It can be used for smoke detectors
Yes, americium is used as ionizing source in smoke detectors.
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.
