The correct statement is: The short-lived positron-emitting isotopes are produced by a cyclotron immediately before use.A cyclotron is a type of particle accelerator that is used to produce high-energy particles, including short-lived positron-emitting isotopes. These isotopes are often used in medical applications, such as in positron emission tomography (PET) scans, where they emit gamma rays that can be detected to create images of the body. The isotopes are typically produced immediately before use to ensure their short-lived nature, which minimizes the time between their production and their use in medical procedures.
