My daughter has been diagnoised with Thyroid Caner.  My question is  she will be receiving radioactive iodine and she will not be able to be around people for 7 days?  Why is this and why you are not admitted into a hospital where you will be in a controled environment?
Yes madam it is usually safe. Ur daughter should not be pregnant, otherwise severe malformations in child. Few side effects may be there, but benefits are more. Radioactive iodine emits radiations that produce effect as well as side effects. These radiations may harm nearby person, so patient is isolated till whole Chat Doctor.  As such hospitalization is not necessary because the vital parameters need not monitoring. Few hospitals have separate radiation rooms, so they allow admission.
