A common issue in nuclear medicine is the short half-life of materials used for tests like PET or CT scans. The materials must be manufactured nearby so that they can be transported to a hospital quickly enough to be used for a patient when needed. It can be a tremendous advantage for a hospital to be near a laboratory capable of manufacturing rare isotopes. A good example of this is the F-18 isotope used for PET scans. It has a half-life of about 110 minutes. If a 50.0 mg sample of F-18 leaves the laboratory at 8:00 am, how many milligrams of F-18 remains in the sample when it arrives at the hospital at 1:30 pm?
