QSA Global, Inc. manufactures Americium-Beryllium (AmBe) sealed neutron sources for industrial gauging and analysis applications worldwide. Our AmBe sealed sources are double encapsulated in stainless steel components and designed to withstand harsh industrial environments.

Americium-241 (241 Am, 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.

Am-241/Be neutron sources for geological prospecting, moisture gauging, activation analysis, nuclear research, and for applications in oil well logging, contain a homogenous mixture of Am-241 and beryllium metal powder. Double-encapsulated stainless steel source; stable, homogeneous active element. ISO rating: C66545.

The neutron energy spectrum of an alloyed Am 241-Be(α, n) source has been determined with a proton recoil spectrometer. The spectrum shows fairly broad maxima at 3.5 and 5 MeV and extends up to 11.5 MeV.
