Question about PET scans (Positron emission tomography)

[QUOTE="PeterDonis, post: 6200433, member: 197831"] I think you mean there is [I]not[/I] much ionization, because the positron emitted in the nuclear reaction will most likely meet up with the electron that now no longer has an atomic orbital because oxygen has one less atomic electron than fluorine. To a first approximation this should produce zero ionization; the complete reaction is fluorine + 9 electrons -> oxygen + 8 electrons + positron + spare electron -> oxygen + 8 electrons (i.e., a neutral oxygen atom) + gamma rays.
