Why are special safety precautions required in nuclear medicine?

• A. They require no precautions
• B. They are safe indoors
• C. Radionuclides continuously emit radiation after administration
• D. They only emit during storage

Answer: (C)

Radiopharmaceuticals used in nuclear medicine are radioactive and keep emitting ionizing radiation after they’re given to the patient. This means the patient becomes a source of radiation for a period dictated by the radionuclide’s decay, and radiation can be present in body fluids and waste as well. Because of that, safety measures are needed to protect health-care workers, other patients, and visitors. Practically, this leads to applying time, distance, and shielding strategies, using proper containment and monitoring, and following procedures for handling, storage, and disposal. The idea isn’t that there are no precautions or that radiation only comes from storage; it’s that radiation continues to be emitted after administration, requiring ongoing precautions.
