Carbon-11 or 11 C is a radioactive isotope of carbon that decays to boron-11. This decay mainly occurs due to positron emission, with around 0.19–0.23% of decays instead occurring by electron capture. [6] [7] It has a half-life of 20.3402(53) min. 11 C → 11 B + e + + ν e + 0.96 MeV 11 C + e − → 11 B + ν e + 1.98 MeV

3 kwi 2019 · The Bottom Line. Carbon-11 is an accelerator-produced, positron-emitting radionuclide. Its physical half-life of 20.4 min is sufficiently long to allow for multistep syntheses while short enough to enable multiple PET scans of the same individual on the same day.
