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 short-lived positron-emitting isotopes for medical and scientific applications. These isotopes are produced on-demand and have a very short half-life, typically ranging from seconds to minutes. This allows them to be used immediately after production, minimizing the time between their production and their application.The other statements are incorrect. Barium is not produced by a cyclotron immediately before use, and iodine-containing solutions are not produced by a cyclotron either.
