Use of Fluorine 18 in Nuclear Medicine Fluorine 18 is a positron emitter with a half life of 109.77 minutes. It is used in PET scans. Decay mode: 9F18 ( 8O18 + +1e0 (1.656 MeV). Oxygen 18 is stable. The positron travels only a few millimetres in the human body before it meets an electron‚ when both are annihilated producing two gamma ray photons.
