The neutron energy spectrum of the JRC 241Am-Li(alpha,n) radionuclide source has been measured at the PTB in Germany using various spectrometry systems, such as Bonner spheres, proton recoil counters and NE213 liquid scintillators. Energy Response: Gamma(X) rays : ≤ ± 20% (50keV to 6MeV, 137Cs reference) Neutron : ≤ ± 50% (250keV to 4.5MeV, 241Am-Be reference) Angular Response: Gamma(X) rays : ≤ ± 20% (Up to ±60degree vertical and horizontal, 137Cs) ≤ ± 50% (Up to ±60degree vertical and horizontal, 241Am) ≤ ± 30% (All around horizontal, 137Cs, free air The energy loss that is due to bremsstrahlung radiation is proportional to Z2 and increases linearly with energy. The conclusion is that at high energy the energy loss resulting from radiation is predominant. The radiation length is defined as the path length of the absorber in which tlie eleetron emerges with l/e of its initial energy.

The full-energy peak (FEP) efficiency, e P (E), can be expressed as the product of the geometrical component, e G , and the intrinsic efficiency, depending on the energy, e I (E) (Moens et al., 1981):P ðEÞ ¼ I ðEÞ G .(1)The geometrical efficiency is defined as the solid angle limited by the source and the detector collimator divided by 4p sr. Gamma ray spectra of strong 241Am sources may reveal information about the source composition as there may be other radioactive nuclides such as progeny and radioactive impurities present. In this work the possibility to use gamma spectrometry to identify inherent signatures in 241Am sources in order to differentiate sources from each other, is investigated.
