There are currently two AHS cyclotrons in Edmonton that produce radiopharmaceuticals for medical use located at: the Cross Cancer Institute and the Medical Isotope and Cyclotron Facility (MICF) at U of A South Campus. These cyclotrons are similar devices but can produce different radioisotopes, offering a more diverse suite of radiopharmaceuticals for medical diagnosis and research. The two cyclotrons in Edmonton have the ability to back each other up during shut-downs or maintenance.
