CardioGen-82 is a radionuclide generator that produces Rb-82 chloride injection; the Rb-82 emits the radiation detected in a PET scan.
Rb-82 is a medical isotope with a short half-life (75 seconds), and is derived from strontium-82 (Sr-82), which has a half-life of 25 days.
Rb-82 is collected from the generator column by injecting a solution of normal saline through the column. Under normal conditions, only the Rb-82 is released into the solution, while the strontium remains attached to the column.
