Why would a doctor most likely restrict a patient’s contact with other people while the patient receives internal radiation?

With some forms of internal radiation treatment, radioactive material can be present in the patient’s bodily fluids. It may leave the body through urine, saliva, or sweat and expose other people, so limiting close contact helps protect them. The correct choice is “Radioactive material can leave the patient’s body through saliva, sweat, and urine.”
