Medical Uses: Americium-241; Californium-252. Authors; Authors and affiliations. Glenn T. Seaborg. 16 Feb 2011 The isotope of americium used in smoke detectors is americium-241, which decays by α emission to neptunium-237 with a half-life of 432.2 Preparation and Uses of Am241 Gamma Sources .
Applications Ionization-type smoke detector. Americium-241 is the only synthetic isotope to have found its way into the household, Neutron source.

Smoke alarm. The alpha particles pass between the two charged Am-241 sources are used for a variety of industrial gauging purposes.

Uses. 241Am has been used as a portalbe source for gamma radiography.
Americium-241 is also used to measure the thickness of materials. For instance, a small piece of americium-241 can be placed above a conveyor belt carrying newly made glass. A Geiger counter, a device for counting alpha radiation, is placed below the conveyor belt.

Americium-241 (241Am) is used in very small quantities in household ionization smoke detectors. Americium is similar to plutonium (Pu) in many ways. While the public accepts the use of minute quantities of 241Am in smoke detectors in their homes, the public reaction to transporting any quantity of 239Pu under suitable controls is very different.
