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.

The NRF31 features digital display and audible alarm. Within Europe 241Am is considered a promising alternative heat source for radioisotope thermoelectric generators (RTGs) and radioisotope heating units (RHUs). As a daughter product of 241Pu decay, 241Am exists in 1000 kgs quantities within the UK civil plutonium stockpile.

Backscatter method. Make first a hole with the help of guide plate and insert the test probe. MC Portaprobe operates by emitting radiation from two safety-sealed radioactive sources: cesium-137, a gamma emitter for density measurement, and americium-241:beryllium, a neutron emitter for moisture measurement. Americium (95 Am) is an artificial element, and thus a standard atomic weight cannot be given.
