Study of Rapid Radiochemical Separation of 90Rb from Fission Product

摘要

<正>90Rb is a high yield and short-lived fission product,and it is a sensitive monitor at low burnup.The decay data of 90Rb are important,however the uncertainty of the decay data of 90Rb tends to be large,such as the half-life data（58±5）s（with an uncertainty of 3.2%）from ENSDF.In order to get the half-life measured more accurately,a carrier-free 90Rb sample of
