“…A need was identified [201] to extend and complete the cross section measurements of 203 Tl(p,p2n) 201 Tl, 203 Tl(p,pn) 202 Tl and 205 Tl(p,3n) 203ml m2m3 Pb processes. Zaitseva et al [202] reported the excitation functions for formation of **>*>< *>2pb with 25.7 to 39.7 MeV protons on 47.9% isotopically enriched 204 Pb. The maximum cross section for formation of 201 Pb was 700 ±100 mb at a flat maximum ranging from 33 to 37 MeV.…”

The present status and future directions of research and development on radionuclide generator technology are reported. The recent interest to develop double-neutron capture reactions for production of in vivo generators; neutron rich nuclides for radioimmunotherapeutic pharmaceuticals; and advances with ultrashort lived generators is highlighted. Emphasis is focused on: production of the parent radionuclide; the selection and the evaluation of support materials and eluents with respect to the resultant radiochemical yield of the daughter, and the breakthrough of the radionuclide parent; and, the uses of radionuclide generators in radiopharmaceutical chemistry, biomedical and industrial applications. The 62 Zn -62 Cu, ^Ni -""Cu, ,03m Rh -• ,03 Rh, ,88 W -• ,88 Re and the 225 Ac -22, Fr -2l3 Bi generators are predicted to be emphasized for future development.

“…Many methods, such as precipitation, coprecipitation, ion exchange, solvent extraction, and their combinations, have been proposed for the purpose (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16). The highest tolerable concentration of inactive thallium in radiopharmaceutical preparation is 2 or 5 mg·dm~3, defined by the United States and European Pharmacopoeia, respectively (17,18).…”

Experimentally obtained extraction isotherms of the system thallium-sulfuric acid-sodium chloride-butyl acetate are presented. The influence of the sulfuric acid and chloride anion concentrations on the extraction equilibria of thallium was investigated. An increase in the acidity of the aqueous phase results in steeper extraction isotherms, and the amount of thallium extracted generally increases. The influence of chloride anions on the equilibrium is more complex. It was found that the extraction equilibria is not influenced by the chloride ion concentration, provided that the Cl/Tl ratio in the aqueous phase is~4. If this ratio is less than 4," the concentration of chloride anions significantly influences the extraction isotherms. The results obtained are discussed in terms of the composition of the complex in the organic phase. An apparent reaction constant equation is proposed for the prediction of the extraction equilibria.
