摘要
Abstract
In order to get the decay data of 90 Rb measured more accurately ,a sample of 90 Rb of radiochemical purity has to be prepared .A separation method was established based on twice delay separation method ,in which the high isotope abundance can be extracted from new produced fission product .First of all ,the gaseous fission product 90 Kr was extracted from the irradiated target by a deflation procedure ,and then through a washing procedure ,the 90Rb generated by 90Kr decay was collected .A system for rapid extracting 90 Kr was also developed .Finally ,a carrier‐free 90 Rb product of high specific activity was obtained .The total recovery of 90 Rb is about 20% .The decontami‐nation factor of the main impurities is about 103 .T he w hole procedure costs in 2.5 min .关键词
