241Am is an isotope of the element Americium. It undergoes alpha decay (it releases 2 protons and 2 neutrons as a Helium nucleus) and creates Neptunium (Np).

241 Am is the most common isotope of americium as well as the most prevalent isotope of americium in nuclear waste. 241Am is produced during irradiation of uranium, which goes through neutron capture during irradiation to 241Pu, which is one of the isotopes that degrades the usefulness of weapons-grade 239Pu. It decays in a very short time (14 day half-life) into 241Am, which is not useful as weapons-grade material, but is still useful in nuclear reactors. Also, 241Am gamma rays can be effectively shielded by thin layers of high atomic number materials (HVL is 1/8th mm of lead) placed on the applicator or inside some body cavities (for example, hypaque in bladder, barium sulphate in rectum).

Safety Data Various OSU researchers have gauges manufactured by Troxler or CPN which use 241Am-Be neutron sources in the measurement of soil moisture content. The source consists of a compressed mixture of americium powder and beryllium powder, doubly encapsulated in welded stainless steel, with a neutron detector and associated electronics in a combination shield and housing.
