Cadmium tubes can be used to shield neutron activation (flux) wires from thermal neutrons and also to manufacture reduction coils used in nitrate/nitrite analysis

​

High-purity cadmium tubes are now available with dimensions of 0.05" (id) x 0.09" (od). We stock sizes 12", 24" and 36" lengths, but can readily cut your order of cadmium tubing to any length
