Separation of 95 Y 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 95 Y, which half-life is 10.3 min. With the best conditions studied in this paper, 95 Y was separated successfully from complicated fission products under the mini-reactor in the China Institute of Atomic Energy. Decontamination factors to other nuclides except 94 Y are higher than 2 × 10 3 .
