abstract = {The basic parameters related to radiochemical separation of
iodine from tellurium and antimony by anion-exchange
chromatography using the resin Amberlyst A26 were studied.
The separation yield of 124I amounted to $96\%$ and the
decontamination factor from 121Te and 122Sb was > 104. The
method was applied to the production of 124I via the
123Sb(α, 3n) reaction. In an irradiation of 110 mg of
natSb2O3 (thickness ∼ 0.08 g/cm2) with 38 MeV
α-particles at 1.2 μA beam current for 4 h,
corresponding to the beam energy range of
Eα = 37 → 27 MeV, the batch yield of 124I
obtained was 12.42 MBq and the 125I and 126I impurities
amounted to $3.8\%$ and $0.7\%,$ respectively. The
experimental batch yield of 124I amounted to $80\%$ of the
theoretically calculated value but the level of the
radionuclidic impurities were in agreement with the
theoretical values. About $96\%$ of the radioiodine was in
the form of iodide and the inactive impurities (Te, Sb, Sn)
were below the permissible level. Due to the relatively high
level of radionuclidic impurity the 124I produced would
possibly be useful only for restricted local consumption or
for animal experiments.},
