Primary and Secondary Source of Neutrons
Sb-Be Source – Antimony-Beryllium Source. Sb-Be neutron source is a typical external neutron source used in commercial nuclear reactors. It is usually loaded into fuel assemblies near the periphery of the core because the source-range excore detectors are installed outside the pressure vessel.Sb-Be source is a two-component source and, prior to …

Lead processing
After this antimony-containing secondary lead is refined, it is largely resold to battery manufacturers. Secondary lead containing tin is most often reused in the manufacture of solder, bearing metals, and other lead-tin alloys. Calcium-lead alloys can also be made from recycled lead. Antimony is removed by oxygen injection, and, after copper ...

antimony, and nickel. The antimony content can be reduced to about 0.02 percent by bubbling air through the molten lead. Residual antimony can be removed by adding sodium nitrate and sodium hydroxide to the bath and skimming off the resulting dross. Dry drossing consists of adding sawdust to the agitated mass of molten metal.

Sb-Be Source
Sb-Be source is a two-component source and, prior to irradiation, contains natural antimony (57.4% of 121 Sb and 42.6% of 123 Sb) and natural beryllium (100% of 9 Be). The first component is a source of strong gamma rays, while the second is a neutron emitter element. Thus the Sb-Be source is based on (γ,n) reaction (i.e., it emits photoneutrons).
