Americium

Domain	Definitions
Chemistry	Chemical element:atomic number 95. Source: European Union. (references)
Health	A completely man-made radioactive actinide with atomic symbol Am, atomic number 95, and atomic weight 243. Its valence can range from +3 to +6. Because of its nonmagnetic ground state, it is an excellent superconductor. It is also used in bone mineral analysis and as a radiation source for radiotherapy. (references)

Specialty Definition: Americium

Americium is a chemical element in the periodic table with the symbol Am and atomic number 95. All isotopes of this man-made element are radioactive. It belongs to the group of the actinides. It was named for the Americass, by analogy with Europium.

Americium was the fourth transuranic element to be discovered; the isotope 241Am was identified by Glenn T. Seaborg, James, Morgan, and Albert Ghiorso late in 1944 at the wartime Metallurgical Laboratory of the University of Chicago as the result of successive neutron capture reactions by plutonium isotopes in a nuclear reactor. The luster of freshly prepared americium metal is white and more silvery than plutonium or neptunium prepared in the same manner. It appears to be more malleable than uranium or neptunium and tarnishes slowly in dry air at room temperature. Americium must be handled with great care to avoid personal contamination. The alpha activity from 241Am is about three times that of radium. When gram quantities of 241Am are handled, the intense gamma activity makes exposure a serious problem. 241Am has been used as a portable source for gamma radiography. Small amounts of Americium-241 has also been used as a radioactive glass thickness gauge for the flat glass industry and as a source of ionization for smoke detectors.
