Radioactive tracers are related to medicine, but they are used in several other fields. . It goes by several names, including radio-pharmaceuticals, radiotracer, and radioactive label. Radioactive tracers are chemical compounds that have radioactive atoms.
These atoms make it easier to be detected, as well as easier to be measured. These tracers are important in many imaging systems of the medical field, including PET scans. They are also used to research elements found in cells and biochemcial reactions.
Another purpose of these tracers is to track how fluids flow in gas. Examples of these tracers include carbon, oxygen, fluorine, iodine, and gallium.
