Gallium and Germanium Isotopes

Ga-67 is produced in cyclotrons (Eq. (8.26)).

Ga-68 can be obtained by reprocessing of spent fuel elements since it is a fission product.

Ge-68 is used in Ge-68/Ga-68 generators. The complexes of Ga-68 have medical applications.

8.6.11 Arsenic-76 (As-76)

As-76 is produced by the 75As(n, Y)76As nuclear reaction. When an organic arsenic compound is irradiated, an inorganic radioactive arsenic isotope is obtained as a result of the Szilard—Chalmers reaction. The inorganic arsenic can be separated by chemical procedures, so As-76 is carrier free.
