The separation procedure for the mixture of radiohygienically important radionuclides using a set of ion exchange columns
with inorganic ion exchangers and seminautomatic SA—7100 separation equipment has been elaborated. Conditions required for
the selective separation of representative radionuclides of corrosion and fission products are given. Quantitative and selective
separation, verified by gamma spectrometry, has been performed in one run within 30 min.
