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. The energy of each gamma ray photon is 511 MeV‚ the rest mass of the electron‚ so presumably the positron looses some energy prior to annihilation
