Production of no-carrier-added ¹²³I via heavy-ion activation of natural antimony oxide

Keywords: Heavy-ion activation, Antimony oxide, 123I, TOA, HDEHP

Activation of natural Sb₂O₃ with 48 MeV ⁷Li³⁺ beam results in the formation of no-carrier-added ¹²³I in the matrix along with the radionuclides ^123,125Xe and ¹²²Sb. The ¹²³I yield amounts to about 400 kBq/μAh and the radionuclidic impurity of ¹²⁴I to ∼1.2% of ¹²³I. Attempts to separate no-carrier-added iodine from bulk antimony target involved liquid-liquid extraction with TOA and HDEHP as well as precipitation of Sb₂S₃ with thioacetamide. The precipitation technique was found to be the most effective for quantitative separation of ¹²³I from the bulk antimony oxide target.
