AMERICIUM 241!
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.
One use is in smoke detectors to warn of fire.
A synthetic element that is used in smoke detectors is
Americium become to be largely used in smoke detectors after 1970.

A synthetic element that is used in smoke detectors is
Americium (element 95 on the periodic table)
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.
Americium become to be largely used in smoke detectors after 1970.
Smoke detectors are devices that detect smoke. They are used as warning devices in houses to warn people of fire.
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.
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.
