205-Pb
I just received the following e mail from Brasilia, perhaps she can get any
help from Radsafers. Please contact her directly. Thanks for the attention

Dear Rozental,
To develop my research work at the University of Brasilia, in the area of U-Pb
Geochronology Methodology, using mass spectrometer, I need ~2 microg of
205-Pb, lead artificial isotope. 205-Pb is a synthetic isotope of great
utility in U-Pb Geochronology. The production path utilizes an enriched
(99.6%) 206-Pb target and
optimizes (p,2n) reactions to form 205-Bi which decays with a 15.3 day
half-life to 205-Pb. The 205-Pb isotope is produced by 24-27 Mev proton
irradiation using cyclotron facilities, using a proton current of ~130 microA.
Do you know who can help me to obtain that radionuclide?
