摘要：

A rapid separation system based on SISAK technique was established to isolate La-142 successfully from fission products. SISAK technique is often applied in the separation of nuclides with the half-life of seconds or minutes. Here it was used to separate the parent nuclide of La-142, which the half-life is in the magnitude of several seconds. According to the separation procedure designed in the paper, the activity of La-142 acquired is more than 10(4) Bq and the decontamination factors for most gamma-emitters are higher than 10(3).
