Americium's longest-lived isotope, americium-243, has a half-life of 7367(23) years. It decays into neptunium-239 through alpha decay. Americium has a few practical uses: as a monitor for radioactive contamination and as a tracer for radiochemical

Standardization of 239Pu using isotopic ratios obtained through alpha spectrometry and mass spectrometry

January 10, 2026

Author(s)

Adam Pearce, Madeleine Bodine, Ronald Colle, Richard Essex, Lizbeth Laureano-Perez, Jerome LaRosa, Leticia Pibida, Mark Tyra

The standardization of a new 239Pu radioactivity solution with considerable impurity was investigated. The massic activity of 239Pu was obtained through 4πα liquid scintillation (LS) counting with correction for significant amounts of other plutonium
