Production of pilot batches 223 Ra and 227 Th of medical purpose

The pilot batches of ThCl and RaCl were separated from Ас. Th was separated by anion exchange chromatography on the sorbent BioRad AG-1x8 100-200 mesh from 8 М HNO . After Th storage accumulated Ra was separated from Th using two chromatography columns: on sorbent BioRad AG-1x8 100-200 mesh from 8 М...

Description
Summary:The pilot batches of ThCl and RaCl were separated from Ас. Th was separated by anion exchange chromatography on the sorbent BioRad AG-1x8 100-200 mesh from 8 М HNO . After Th storage accumulated Ra was separated from Th using two chromatography columns: on sorbent BioRad AG-1x8 100-200 mesh from 8 М HNO followed by eluate evaporation, by dissolving of dry residue in 0.02 М EDTA with рН 4.5 and sorption on cation exchanger BioRad AG-50x8 200-400 mesh. The samples obtained were analyzed by gamma-, alpha- and atomic emission spectrometry methods. Long-living Ас content in Ra and Th was determined by a preliminary chemical separation.
