Abstract

The corrosive behaviour of caesium has been attributed in part to the presence of a non-metallic impurity such as oxygen. A photon-activation method for determining oxygen and carbon in caesium is described. Scintillation coincidence-counting and pulseheight discrimination are used to count the gamma-ray activity resulting from annihilation of the positrons emitted. Variation of beam energy has been investigated in order to obtain optimum irradiation conditions. In the samples analysed and under the conditions used, less than 100 ppm of oxygen and carbon can be detected. Results are compared with those from other methods.
