Neutron spectra of 241 Am 9 Be (α,n) sources have been calculated by using the most recent data on angular distributions. The contribution from the multibody break-up reaction 9 Be (α,αn) 8 Be has also been incorporated by using the measured angular distributions of this reaction at various energies.

The neutron emission probability of the 241 Am-Be neutron source at thermal energies had been measured using indium, gold, and manganese foils as monitors for thermal neutrons. Am(Be) this is currently 391 pSv cm 2. Values of neutron fluence to dose equivalent conversion factors in this international standard are taken from ICRP publication 21. These values refer to irradiation by a unidirectional broad beam of mono-energetic neutrons and are evaluated at the maxima of the depth-dose equivalent curves.

Neutron spectra of 241 Am 9 Be (α,n) sources have been calculated by using the most recent data on angular distributions. The contribution from the multibody break-up reaction 9 Be (α,αn) 8 Be has also been incorporated by using the measured angular distributions of this reaction at various energies. An Am/Be neutron source, installed recently at the Rajshahi University, is described. Neutron flux mapping was done using the nuclear reactions (197)Au (n,gamma) (198)Au, (113)In (n,gamma) 241Am–Be(α,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 241Am–Be source was measured in the energy region above 1.65 MeV using a BC501A proton-recoil liquid scintillator. A neutron source is any device that emits neutrons, irrespective of the mechanism used to produce the neutrons.
