title: Radionuclide impurities in [¹⁸F]F⁻ and [¹⁸F]FDG for positron emission tomography.
abstract: The paper describes radionuclide impurities (γ-emitters and (3)H) in proton irradiated (18)O enriched water from an Nb target vessel with Nb entrance window, their distribution in different synthesis steps and finally in the PET radiopharmaceuticals [(18)F]Fluoride and [(18)F]FDG.
