- Abstract
In this work details of safe radium source disassembly which were previously used in brachytherapy are described and different methods for conversion of RaSO into aqueous solution are reviewed. The method of choice included three cycles of RaSO heating in 1.5 M NaCO up to 85 °C, cooling and subsequent removal of supernatant. X-ray diffraction study showed that the method allows the synthesis of, presumably, amorphous RaCO, which can be dissolved in mineral acid. Gamma spectrometric measurements showed that most of the initial RaSO was converted into solution and that 7 ± 1 % of the initial Pb was co-precipitated with RaCO.
