Vs. Guselnikov et al., RECOVERY OF RADIOACTIVE THALLIUM ISOTOPES FROM LEAD AND BISMUTH TARGETS IRRADIATED BY 1-GEV PROTONS, Radiochemistry, 37(2), 1995, pp. 159-162
A simple highly efficient procedure has been developed for recovery of
thallium radioisotopes from lead and bismuth targets irradiated by 1-
GeV protons. The procedure is based on the use of extraction chromatog
raphy. The cross-sections have been determined for formation of Pb-200
, Pb-201, Pb-202m, and Pb-203 radioisotopes in targets from lead with
natural isotopic composition, irradiated by 1-GeV protons.
