Its most important isotope is americium-241 (half-life 432.7 years), which is produced by the beta-decay of plutonium-241. Americium-241 is used commercially in applications such as smoke detectors, thickness gauges, and fluid level gauges. Recommended Nuclear Decay Data Am-241 . Decay Mode: α. Half-Life: (157850 ± 240) d [2] 2013-01-24 Americium (95 Am) is an artificial element, and thus a standard atomic weight cannot be given.

The radiation from the decay of americium-241 and its Americium is a man made radioactive isotope, and is commonly found in smoke detectors. The source is an alpha emitter, and in the decay process it also kicks out a gamma at 59.6KeV.

The longer spent nuclear fuel waits before reprocessing, the more 241 Pu decays to americium-241, which is nonfissile (although fissionable by fast neutrons) and an alpha emitter with a halflife of 432 years; 241 Am is a major contributor to the radioactivity of nuclear waste on a scale of hundreds or thousands of years.

Americium-241 is an unstable isotope. As americium decays, it releases radiation and forms “daughter” elements. The first decay product of americium-241 is neptunium-237, which also decays and forms other daughter A smoke detector containing an americium-241 ionization chamber accumulates a significant amount of neptunium-237 as its americium decays; the following elements are also present in it, at least transiently, as decay products of the neptunium: actinium, astatine, bismuth, francium, lead, polonium, protactinium, radium, thallium, thorium and 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 years. (The isotope americium-243 also decays by α emission and is longer-lived at 7370 years, but it is obtained Favorite Answer There are only 4 decay series that exist.
