Note: The calculation of radioactivity in minerals is based on certain assumptions. The nature of the decay chain of plutonium-241 (discussed above) is such that the disposal history of a particular site and the chemistry of the disposed wastes can impact the degree of separation that can occur between plutonium and americium-241.
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. the 4N series, the 4N+1 series, 4N+2 and 4N+3 series. Divide 241 by 4 and you get 1 remainder.

Americium-241 is also suitable for calibration of gamma-ray spectrometers in the low-energy range, since its spectrum consists of nearly a single peak and negligible Compton continuum (at least three orders of magnitude lower intensity). Americium-241 gamma rays were also used to provide passive diagnosis of thyroid function. Some of the other isotopes have been detected in nature, originating from trace quantities of 237 Np produced by the (n,2n) knockout reaction in primordial 238 U. 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
Americium-241 decays by alpha emission, with a by-product of gamma rays.

In some kind of smoke detectors, you can meet radionuclides from this series. Ionization smoke detectors usually use a radioisotope, typically americium-241, to ionize air and to detect smoke.
