A radionuclide will then be injected or taken orally. This makes it possible for the camera to detect certain organs and their functions. The amount of radiation to which the patient is exposed is minimal and of no significant danger. The radionuclide or tracer material is eliminated from the body in a day or two. Complications or side effects are rare.
