Various parameters that affect photon and neutron yields and energy distributions were investigated. (241)Am-Be(alpha,n) neutron sources provide one of the most commonly used neutron fields for routine calibration of neutron sensitive devices. The neutron energy distribution of the IRSN standard (241)Am-Be source was measured in the energy region above 1.65 MeV using a BC501A proton-recoil liquid s … Separation and Activity Determination of 239+240Pu, 241Am and Curium (242 and 244Cm) alpha spectrum. In this work it was used tracers, 238Pu, 243Am, 241Am decays to an isotope of neptunium (237Np), emitting an alpha particle with an energy of approximately 5.5 MeV and gamma rays, with the majority having an energy of 60 keV. 237Np has a half-life of 2.14 million years, and also decays by alpha emission (4.9 MeV). Because of its long half-life, 237Np is less hazardous than Alpha and conversion electron spectroscopy of 238,239Pu and 241Am and alpha-conversion electron coincidence measurements Figure 1.

Americium-241 (241Am, Am-241) is an isotope of americium. 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.

The following spectrum of 241Am, was submitted by Peter Daley, recorded with a GS-1100A and a 2" Alpha Spectra NaI detector. Excellent resolution and a very typical 241Am shape. Recognising isotopes by the shape of their spectra is an art and takes practice, which is why we are building this database of spectra.
