Separation Of Y-95 From Fission Products By Sisak And Extraction Chromatography Technique

Radioactivity measurement of short-lived nuclides is the basis of decay data measurement, which requires rapid separation and purification of the interested nuclides from complicated fission products. A rapid separation system based on SISAK and extraction chromatography technique was established to isolate Y-95, which half-life is 10.3 min. With the best conditions studied in this paper, Y-95 was separated successfully from complicated fission products under the mini-reactor in the China Institute of Atomic Energy. Decontamination factors to other nuclides except Y-94 are higher than 2 x 10(3).
