| Abstract: |
We have proposed to produce a 229Th/225Ac generator by neutron irradiation of the 228Ra target, which is a decay product from 232Th. The solutions containing 232Th and 228Ra were obtained through the thermal chemical conversion method to dissolve the ThO2. Then, the separation of 228Ra from thorium solutions through co-precipitation with magnesium was studied. It was confirmed that radium is coprecipitated by this method. It was also confirmed that the precipitated magnesium carbonate can be easily converted to magnesium oxide. The decontamination of thorium from precipitated radium was investigated, and it was found that a rough decontamination of thorium was achieved by co-precipitation methods. The decontamination of thorium depends on the chemical conversion conditions and the dissolution methods used. [ABSTRACT FROM AUTHOR] |
