Four different neutron sources were studied: (i) 241Am/Be, (ii) 252Cf, (iii) 241Am/B and (iv) DT neutron generator. Normalized neutron spectra for four sources are shown in Fig. 2.

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. The neutron source used was a sealed 241Am-Be(α,n) source (model AMN22, serial number AMN1000/1096) owned by the NPL, which had a nominal activity of 37 GBq (1 Ci). It is in an X3 capsule (outer length 31 mm, outer diameter 22.4 mm) a type currently manufactured by QSA Global. The source was chosen for its long half-life and stable decay process, and also because it is 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)(114m)In, (115)In(n,n'gamma)(115m)In and (58)Ni(n,p)(58)Co. Safe, cost-effective and homemade design of diminutive Am–Be neutron source is obtained by combining an alpha source as an active component and a disk of light metal as a target. The neutron energy spectrum of an alloyed source was determined with a proton recoil spectrometer.

Abstract. 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)(114m)In, (115)In(n,n'gamma)(115m)In and (58)Ni(n,p)(58)Co.

Am/Be source, fig. (2) shows the stainless steel capsule types while table (4) gives its dimensions. Table (5) gives the activity, emission neutron n/s, capsule type and its code for this isotopic neutron source (taken from ref. 3). •28- The neutron energy spectrum of the following sources were measured using a fast neutron spectrometer with the NE-213 liquid scintillator: 252Cf, Am-Be and D(d,n)3He reaction from a 3 MeV Pelletron accelerator in Tokyo Institute of Technology. The measured proton recoil pulse height data of 252Cf, Am-Be and D(d,n)3He were unfolded using the mathematical program to obtain the neutron energy Am-Be isotopic neutron sources were used.
