摘要：

Growing interest in the research of radium chemistry, its use as target material in nuclear reaction studies and preparation of calibration sources leads to higher demand for Ra-226 in readily available soluble form. Aged radium needle sources containing very insoluble radium-barium sulphate may serve as source material of Ra-226 and its decay products (e.g. Pb-210). We describe here several methods for [Ra-226]BaSO4 dissolution including microwave assisted reactions and compare their efficiency in model experiments.
