Abstract

The production of201 Tl is described. Natural thallium is irradiated with protons and the induced201Pb is separated from the target by liquid-liquid extraction with diethyldithiocarbamic acid in chloroform.201Tl is separated from the mother activity (201Pb) by liquid-liquid extraction with the same reagent. The decontamination of the final product (carrier free201TlCl) is ≥5·106 from the thallium of the target and>5×104 from lead isotopes.
