Radioactive iodine therapy requires precautions to prevent spread to others, typically including which of the following?

• A. No restrictions after discharge
• B. Isolation for the recommended period
• C. Wearing a mask at all times
• D. Frequent swimming sessions

Answer: (B)

After radioactive iodine therapy, the patient emits radiation that can expose others. To minimize that exposure, isolation for the prescribed period is used, until the level of radioactivity decays to safe levels per facility policy. This approach directly reduces the chance of close contact and sharing living space while the patient remains significantly radioactive. The other options don’t protect others: there are usually some restrictions after discharge, wearing a mask isn’t the standard method for preventing spread of radioactivity, and swimming would expose others to radioactive material.
