Most americium is produced by uranium or plutonium being bombarded with neutrons in nuclear reactors – one tonne of spent nuclear fuel contains about 100 grams of americium. It is widely used in commercial ionization chamber smoke detectors, as well as in neutron sources and industrial gauges.

How is americium produced?
Americium (chemical symbol Am) is a man-made radioactive metal that is solid under normal conditions. Americium is produced when plutonium absorbs neutrons in nuclear reactors or during nuclear weapons tests. Americium-241 is the most common form of Americium.
Is americium natural or synthetic?
americium (Am), synthetic chemical element (atomic number 95) of the actinoid series of the periodic table. Unknown in nature, americium (as the isotope americium-241) was artificially produced from plutonium-239 (atomic number 94) in 1944 by American chemists Glenn T.
What household device uses the synthetic chemical element americium?
The two major types of household smoke detectors are ionization smoke detectors and optical smoke detectors. Most common household ionization smoke detectors use Americium-241 in the form of Americium Dioxide as its source of the ionizing radiation that the smoke detector needs to work.
How is americium an element?
Americium is a synthetic radioactive chemical element with the symbol Am and atomic number 95. It is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas.
What are 3 uses of americium?
Americium is a portable source of gamma-rays and alpha particles for a variety of medical and industrial uses such as radiography and spectroscopy, helping to create flat glass by gauging its thickness.
What are three uses for americium?
Americium has some uses: it is used in some smoke detectors, as portable gamma ray source in radiography, to help to create flat glass. However this isotope is extremely expensive to produce in usable quantities.
How many isotopes does curium have?
Fourteen isotopes of curium are now known ranging in mass from 237 to 251.
Where is curium found in the world?
Curium does not occur naturally; it is typically produced artificially in nuclear reactors through successive neutron captures by plutonium and americium isotopes.
How many isotopes does americium have?
About 19 isotopes and 8 nuclear isomers are known for americium. There are two long-lived alpha-emitters, 241Am and 243Am with half-lives of 432.2 and 7,370 years, respectively, and the nuclear isomer 242Am has a half-life of 141 years.
What happens if you touch americium?
Exposure to extremely high levels of americium, as has been reported in some animal studies, has resulted in damage to organs such as the lungs, liver, kidneys, and thyroid. It is rare, however, that a person would be exposed to amounts of americium large enough to cause harmful effects in these organs.
