carbon-11 (11C)

a radioisotope of carbon with a half-life of 20 minutes. It is produced by a cyclotron and emits positrons. Compare carbon-14.

carbon-11

A positron-emiting radioisotope of carbon, which is produced in a cyclotron, has a T1/2 of 20.38 minutes, decays 100% by positron emission to 11B, and is used in PET scanning.
