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.
Americium (pronounced /ˌæməˈrɪsiəm/) is a synthetic element that has the symbol Am, the atomic number 95, and is used in smoke detectors.
Americium (isotope 241) is the most common radioactive element used 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.

One use is in smoke detectors to warn of fire.
Americium (element 95 on the periodic table)
Americium is a synthetic element that has the symbol Am and atomic number 95. A radioactive metallic element, americium is an actinide that was obtained in 1944 by Glenn T. Seaborg who was bombarding plutonium with neutrons and was the fourth transuranic element to be discovered. It was named for the Americas, by analogy with europium. Americium is widely used in commercial ionization-chamber smoke detectors as well as in neutron sources and industrial gauges.
