Does having iodine 131 affect the house you live in?

Iodine 131 may affect the environment of the house where the patient lives.
After iodine 131 treatment, there may be radioactive substances in the patient’s body, and these substances can be discharged with the patient’s sweat, urine and other body fluids, so it may affect the living environment. For safety reasons, you can sleep in a separate room with your family members for a short period of time after the treatment, and return to normal life only after the radioactive substances in your body have been metabolized.
In addition, avoid contact with infants, young children, pregnant women and other people for one month after treatment, and suggest separate treatment for clothes contaminated by sweat and urine.
Patients who have undergone Iodine 131 treatment can consult a professional doctor for related precautions.
