USE OF NEUTRON-ACTIVATION ANALYSIS FOR THE DETERMINATION OF CESIUM INPD ELECTRODES ON PT AND AU MATRICES

A method of neutron activation analysis (NAA) for the determination of Cs inside a thin Pd electrode deposited on a Pt or Au matrix is repor ted. This simple and rapid method involves a post-irradiation radioche mical separation of Cs from high activities of interfering radionuclid es. The separated Cs was determined by high resolution gamma-ray spect rometry. The method allows the determination of Cs without a time-cons uming cooling period. The radiochemical procedure (RNAA) is found to b e relatively highly precise sensitive, rapid and simple. Pre-irradiati ve chemical separation of Cs is likely to be reasonable.
