The Preparation of Carrier-Free Radium-228 Using Cation Exchange Columns

The need for a radium tracer of reasonable half-life, low cost and ready availability, led us to the preparation of carrier-free radium-228 from thorium nitrate known not to have been separated from its daughter products for at least 12 years. Solvent extraction and cation exchange techniques were u...

Zusammenfassung:The need for a radium tracer of reasonable half-life, low cost and ready availability, led us to the preparation of carrier-free radium-228 from thorium nitrate known not to have been separated from its daughter products for at least 12 years. Solvent extraction and cation exchange techniques were used. The preparation is rapid and the characterisation of the end product by radiometric methods is straightforward.
