solutions from whkh 241Am and 237U have been removed. If too much 241Am is present, its 60-keV gamma ray overwhelms all other peaks in the region. Usually, the 40-keV region is useful for 15 to 30 days after a separation of americium and uranium. A typical spectrum from a high-burnup reprocessing plant solution

241am alpha spectrum

Like all isotopes of americium, it is radioactive, with a half-life of 432.2 years. 241 Am is the most common isotope of americium as well as the most prevalent isotope of americium in nuclear waste.
