241Am is a "kinder and gentler" isotope than 238Pu to access since it's sourced from reprocessing nuclear waste from power generation and doesn't have to be "made to order" in a special reactor. Fig. 1. 241 Am α -particle source mounted in the holder/collimator assembly used to define a beam of α -particles.

For offsite, the highest maximum dose is due to 241Am (6.18 mSv y-1), which is more than 22 times the maximum doses from 137Cs and 252Cf. History (the Americas) Americium was the fourth transuranic element to be discovered; theisotope 241Am was identified by Seaborg, James, Morgan, and Ghiorso late in 1944 at thewartime Metallurgical Laboratory of the University of Chicago as the result of successiveneutron capture reactions by plutonium isotopes in a nuclear reactor.

The certified values of 5.696 (11)·10-9 mol g-1 and 0.136138 (54) were assigned for the amount content of 243Am and the n(241Am)/n(243Am) amount ratio, respectively. Abstract. The neutron energy distribution of the IRSN standard 241Am–Be(α,n) source was measured using a proton recoil liquid scintillator, BC501A, >1.65 MeV recommended spectra for 241Am-B and 241Am-F, respectively.

241Am (Americium) 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. Americium-241 Please visit the Americium element page for information specific to the chemical element of the periodic table. Radionuclide Basics: Americium-241 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.
