By irradiation of a tin target (antimony content, less than 8 x 10/sup - 4/%) with 15 Mev protons (120 mu amp hr), about 1 mC of Sb/sup 120/ was produced, with a specific activity more than 30 mu C per mu g of antimony. The radioactive antimony was either separated by extraction with amylacetate from more than 6 N hydrochloric acid containing tin(IV) or by cation exchange in a 0.4% tartaric acid solution of pH 0.6 to 1.6 containing tin(II). Sb/sup 120/ is electrolytically deposited on an evaporated film of silver or copper from a 1 to 3 N hydrochloric acid solution containing 1% hydroxylamine hydrochloride with a yield of 70% within 3 hr. Care should be taken to avoid hydrolytic aging of antimony in diluted hydrochloric acid, which vitiates the extraction, the ion exchange, and the electrolysis. (auth)
